System Overview

• The Tire Pressure & Temperature Monitoring System comes with a monitor that can handle up to 22 wheels with pressure up to 210 PSI. The sensors are lightweight and do not affect tire balance. They have easy-to-change replaceable CR1632 batteries.
• The system offers a method of separately monitoring either the towing vehicle or the towed vehicle. This allows you to monitor the towing vehicle without a towed vehicle or the towed vehicle when driving away from the towing vehicle.
• The monitor automatically scrolls through each wheel, measuring tire pressure and temperature, and displays the readings on the monitor. Alarms can be preset by the operator to provide visible and audible warnings for rapid air pressure loss, high or low pressures, and high temperature. The alarms and monitoring are sent wirelessly in real-time to the cab, allowing the operator to monitor tires that are out of their vision. The audible alarm eliminates the need to watch the monitor continually.

SYSTEM COMPONENTS

SYSTEM OVERVIEW

• The system comes with a monitor that can handle 22 wheels with pressure up to 210 PSI. The sensors are light weighted and do not affect the tire balance and have easy to change replaceable CR1632 batteries. The system offers a method of dropping either the towing vehicle or the towed vehicle separately. This allows you to monitor the towing vehicle without a towed or the towed when
  driving away from the towing vehicle.

• The monitor scrolls automatically through each wheel measuring tire pressure and temperature, displaying it on the monitor. Alarms can be preset by the operator so visible and audible alarms can warn the driver of a catastrophic failure (rapid air pressure loss), high or low pressures and high temperature. The alarm and monitoring are sent wireless in real time to that cab allowing the operator to monitor tires that are out of their vision. The audible alarm eliminates the needs to watch the monitor continually.

• Tire Pressure can be displayed in PSI or BAR and temperature in Fahrenheit (℉) or Celsius (℃). Pressure alerts can be set to a different pressure setting for each axle, so additional towed trailers or vehicles are no problem. An optional booster can be purchased from your dealer or your local distributor if you have signal loss due to distance, structural or electronic interference.

• Tire monitor has a rechargeable lithium Ion battery, Sensors come with either the Anti-theft security feature or Flow-through feature. The monitor comes with a Type-C charging cable.

GENERAL INFORMATION

• A tire professional or your vehicle owner’s manual should be used to determined the proper tire pressure for your vehicle. Recommended operating tire pressures should be set when the ambient temperature is low or cold.

• Dramatic changes in tire pressure can occur because of; increased or decreased ambient temperature, tire contact surface temperature, wheel and axle loads, sun shining on a side, etc. These and other conditions should be taken into consideration when setting initial tire operating pressures.

• This system cannot warn you of side wall failures; however, it can supply you with irregular pressures and temperature information that may help to prevent
  this. If the monitor is shut off overnight simply switch the monitor back on before departure and your real time tire pressures and temperatures will be updated typically appear on the screen within 5 to 10 minutes. Even if the monitor is in the sleep mode the system is always monitoring and will alarm should any pressure settings or temperatures be out of your set parameters.

• The Schrader Valve (core inside the valve stem) should be the correct size, be in good condition and be able to be depressed fully to allow the release of air to the sensor so it can operate. Some valve stem extensions may cause inaccurate readings if they don not enable the sensor to work correctly, metal bodied
  stems, or T-Valve type is recommended for best performance. Should you have difficulty with a pressure sensor not working properly, we recommend that you contact a professional to ensure the tire stem and Schrader Valve are installed and operating properly. If using internal tire sealants or balancing compounds / beads, check with the manufacturer to ensure they are compatible with TPMS systems or that you have filtered valve cores installed. Over a period, tires may lose pressure naturally, through the tire itself or for other reasons such as rim leakage, etc.

• After installing the sensors on a tire valve stem, it is recommended to perform a soapy water test using 1/4 dish soap and 3/4 water. Spray the soapy solution on the valve stem and sensor area to ensure the sensor is seated all the way. If air bubbles are seen in any of these areas, the tire may deflate. The wheel sensors are weatherproof and can be run in the rain.

Consult a tire professional if any of these areas prove to be a problem.

• Purchasers of this product should not solely rely on this tire pressure monitoring system for safety and should check the condition and pressure of their vehicle’s tires on a regular basis as described by the manufacturer of the vehicle or tire manufacturer. Please note, this TPMS system works on an RF system, as with many RF tire systems this system can occasionally suffer from interference depending on the location of the system; thus, causing the system to be in accurate or not operate at all. Tire pressures and temperatures are not the only things that can affect tire safety; we suggest daily visual inspections and periodic checks by tire professionals.

START YOUR NEW SYSTEM SETTINGS (ALERT PARAMETERS)

1. Unpack all the components of your TPMS system and ensure it is complete.
2. Take the number kit from the accessory pack and number all your sensors as indicated below. (Tips: After put the stickers to the sensors, take some clear nail polish and paint over the number. It will keep the sticker on the sensors for much longer time in wet weather conditions.)
3. Program the alarm parameters using STEP 1 setting your system alarm parameters.
4. Program each sensor to the monitor using METHOD 1 tabletop page 7 programming sensors to the monitor

STEP 1: SETTING YOUR SYSTEMS ALARM PARAMETERS
Refer to the diagram on the last page of this manual where you wrote the“ HIGH and LOW” pressure for each axle.

1. 1. Next to each axle write down what your tire pressure is by axle and calculate what your alarm setting will be.

2. High-Pressure setting will be (20% above axel tire pressure).
3. L ow-Pressure setting will be (10% below axel tire pressure).
   Example: Front Axle Tire Pressure is: 100 PSI
   High-Pressure Alarm Setting will be :120 PSI (100 PSI x 1.2 (or 120%) = 120 PSI
   Low-Pressure Alarm Setting will be : 90 PSI (100 PSI x 0.9 (or 90%) =90 PSI
   These are industry standards for the initial set-up. Some adjustment may be needed on your first trip. For the temperature, it is recommended leaving it at the factory default if 158 degrees ℉.

STEP 2: Choosing Pressure and Temperature Unit of Measure:
PRESS and HOLD the SET button until you hear the beep. You will see PSI flashing on the middle of the screen. Press the SET button again and you can change to BAR by press the + or – Key to scroll between the two. When the one you want to use appears on the screen, press and release the SET button. (Pressing and releasing the SET button in this mode is like saying yes to what the screen is showing you.) Press the SET button again and“ ℉” will be flashing. Press + or – to change to
℃ if you need.

The next time that you press the SET button, the front axel will be flashing and the words“ HIGH PRESSURE” will be displayed. Follow the instructions below.

STEP 3: Choosing per Axle High and Low Parameters:
Using the set key scroll to your first axle“ High” pressure. Use the plus or minus to set your HIGH PRESSURE. When you reach your desired pressure display, release the SET button again and“ LOW PRESSURE” will be displayed. Use the plus or minus key to set your low pressure. Press the SET button again and the next axle will flash“ HIGH PRESSURE”. Make you’re adjustments the same way as for the first axel. Skip any axles that you are not using and just keep hitting the SET button until you go to the axle that you want to see. When you have finished setting your parameters PRESS and HOLD the SET button until the monitor beeps and you are back to display mode. Keep in mind that the monitor will time out in 40 seconds. So, write down your settings before you start.

PROGRAMMING SENSORS TO THE MONITOR
Method 1 – Tabletop Programming (this is the easiest way)

1. PRESS and HOLD button to turn on the monitor. Place the monitor flat on the table in front of you. Then place your numbered sensors on the table about a foot away from the monitor.

2. Press and hold the CODE button on the lower right side down until you hear the monitor beeps and all the 26 tires show up with number 1 tire blinking. After programming, only those tires that you program will show on the monitor. Place the monitor flat on the table and and then place your number 1 sensor on the table make sure that the sensor is touching the base of the monitor next to the CODE button. You will see“ FFF FFF” on the screen. All F’s means that, the
   sensor is not programmed yet. Then press and release the CODE button on time quickly. The monitor will beep, and a random code will be displayed. Press the
   plus button to go to the next tire and do the same for each tire that you have and so on.

3.  When you have programmed the last sensor, press the CODE button down until the monitor sets off the alarm. Then turn off the monitor then turn it on again to make sure the tires are programmed in the right position.

4. Install your sensors to the valve stems in the order that you programmed them. Give the monitor 5 to 10 minutes depending on the number of
   sensors that you have. Once the sensors are synced you will not have to re- sync unless you turn off the monitor. You will not lose any data if you turn off the monitor. But you will have to wait for the system to re-sync when you turn off the monitor back on. You can leave the monitor turned on by the monitor’s battery power. Then monitor internal battery will run for about 60 hours or 30 days between charges

NOTE:
If you get an ID LF ERROR (low frequency), error code, hit the sensor hard on the table or turn the sensor upside down to wake it up and repeat the operations above. If you still get the ID LF ERROR, press the CODE button and release, pause and then press the CODE button and release again. If it still gives ID LF then
check the battery voltage with a voltmeter. The voltage on a fresh battery should be 3.2V. If it is at or below 2.8V replace the battery with a fresh one.
Make sure that the battery is installed in the proper orientation as shown in this manual.

Method 2 – Air Inflation Activation

1. PRESS and HOLD button to turn on the monitor.
2. Place the sensors on the tires as numbered on your diagram but not under air pressure yet.
3. Press and hold CODE button until you hear the monitor beep. At this time, you will see all 26 tires on the monitor screen and the right front (#1 passenger side) tire should be flashing. Use the + or – button to move to the tire you want to program. Place the monitor within 3 inches of the sensors and screw the
   sensor all the way on. Wait a few seconds and the monitor will beep and a random code will be displayed. If it does not, press and release the CODE button
   once. Once coded press the plus button to go to the next tire (#2 driver’s side) and repeat the steps. Use the plus key to go to the next tire and repeat. Skip any tire that is not on your rig.

YOUR SYSTEM IS NOW SET-UP AND READY FOR USE MONITOR DISPLAY IN OPERATING MODE:-

• After the sensors have all been programmed and the system is in operating mode, the display will automatically scroll through each monitored tire one by one. The tire being transmitted will flash on the screen, and the pressure and temperature for that wheel will be displayed on the monitor. When the monitor
  is initially turned on, it may take up to 5 to 10 minutes for the monitor and sensors to sync up before the pressure and temperature will show on the
  monitor. Wait for all the tires to read before driving. After this time if you see one sensor is till not transmitting the pressure and temperature, you may want
  to reprogram the sensor. On an initial set up, it the tire still fails to indicate a pressure and temperature remove the sensor and back the Schrader Valve
  (valve core) out approximately 1/8 to 1/4 turn and re-install the sensor. This will ensure there is enough contact and air pressure to the sensor.

NOTES and RECOMMENDATIONS:
There will be an audible single“ chirp” and the tire will flash if the monitor has not received a reading from that tire after 30 minutes. If you are still receiving PSI and temperature readings from the sensors, then the chirp is an indication of low battery on that sensor. You can also manually scroll through the tires one by one by pressing the + or – button. If you manually select a tire the monitor will show its readings for 10 seconds. The monitor solar panel works as the light sensor. When you see the solar power charging icon is shown on the top left side of the screen, it means there is enough light for solar panel to turn on the charging, the backlight will be turned off to saving battery power. If there is dark enough the backlight will automatically turn on if you could not see the solar power icon on the screen. The monitor comes with a built-in motion sensor; it will go to sleep (energy saver mode) if there is no movement of the vehicle detected for approximately that the monitor is shut off when the system is not in use, or you are staying in the vehicle overnight. When external power is applied to the monitor it will override the manual on/off switch on the left side. You will get a longer service life from your monitor’s internal battery, if you disconnect the external power source and allow the battery to deplete through normal operations ever  couple week’s naturally.

Factory Defaults

• The factory default settings are as follows:
• High Pressure 175 PSI (12.1 BAR),
• Low Pressure 35 PSI (2.4 BAR),
• Temperature 158℉ degrees (70℃).

RESTORE PARAMETERS to FACTORY DEFAULTS:
Turn off the monitor; press the SET button and activate the monitor at the same time. The RED light will flash, and factory settings will be restored. To delete a sensor ID see page 12.

MONITOR INSTALLATION

Your system comes with two mounting options: a plastic tower with suction cup mount for window or dash, low profile mount for dash. Some people prefer to use Velcro or the small bean bags used for cell phones on their dash.
Mount it onto the window screen or left side window using the suction cup provided ensuring you do not obstruct the driver’s vision of the road. Plug the power adaptor into the cigarette lighter or auxiliary power outlet and connect the power cable to the monitor. Ensure the pin is aligned straight when inserting it into the right side of the monitor. When hard wiring it is recommending using a“ keyed” power source.

1. Take out the lock nut out from accessories pack and screw it onto tire valve.
2. Install the sensor onto tire valve and tighten it by hand.
3. Use the wrench provided to screw the lock nut onto the sensor anticlockwise.

NOTE: Please switch on your display before sensor installation .

1. Install the sensor onto tire valve
2. Tighten the sensor onto tire valve clockwise
3. Tighten the lock nut onto the sensor anticlockwise

DELETING SENSOR ID

1. In operating mode, press and hold CODE button until the monitor beeps and all 26 tires are showing. Press the + or – button to select the desired tire.
2. Press and hold the SET button for 3 seconds. A double beep sound will be issued, and you will see“ FFF FFF” after the sensor code is deleted successfully. Use the + or – key to go to the next tire that you want to delete. To return to operating mode, press and hold CODE button until you hear the monitor beep.

• OTHER FUNCTIONS Typical scrolling Display During normal operation, the monitor scrolls through and shows the tires one by one for approximately 6 seconds. A single audible
  chirp will be issued if the monitor does not receive one of the sensors data for more than 30 minutes. You can manually scroll through and select the tire by
  pressing the + or – button.

• Backlight and Motion Sensor

  • The monitor has a built-in light and motion sensor. The backlight turns on when it detects the vehicle is in motion and when it is dark enough, or you may wave your hand in front the monitor to activate it. Press any button on the monitor to turn on the backlight manually. The monitor will enter sleep mode to conserve battery life if the motion sensor does not detect motion for 15 minutes. It will come back to operating mode when it detects the vehicle is moving again or other motion.

• Temporarily Remove Towing Vehicle or Towed/ Trailer Image from Screen

  • To drop the image of the towing vehicle from the screen press and release the SET and + key at the same time. To display it back on the screen press and release the SET and + button at the same time again. (This will allow you to use the system in your towed when not connected to the coach.)

• To drop the image of the towed vehicle/trailer from the screen press and release SET and – button at the same time. To display it back on the screen, press and
  release the SET and – button at the same time again.

Charging the Monitor
The lithium-ion battery inside the monitor, when fully charged can run for up to 60 hours between charges. When the battery symbol bars are gone, a recharge is required.
OUT OF PARAMETER ALERTS
The system cycles from tire to tire every 6 seconds. If there is a meaningful change in pressure or temperature in this cycle it will transmit to the monitor.
If not, it will maintain the reading and transmit a full update every 5 minutes. This is to conserve the sensor battery. If any reading goes out of the real-time alert; you will notice three things:

1. An audible alarm.
2. A flashing screen backlight in red.
3. The corresponding tire on the monitor will flash, and a text message of what is wrong will appear on the screen.
4. Press any button on the display and the alarm will stop. However, the red light ill not be turned off until the correct pressure and temperature settings are restored to within range.

   NOTE : Replace a new waterproof O-ring from the accessory pack if it’s broken
   When you open the sensor note the thin black wire, it is the sensors antenna.
   Do not break it. Broken antenna wire caused by replacing battery.

Flow Through Sensor Battery Replacement
When you hear the low battery beep, the next time you park the vehicle watch the monitor. Every time the monitor comes to that sensor the monitor will beep. Install CR1632 battery operates at -20℃ to 80℃. These can be purchased at many hardware stores, Radio Shack or large Walmart online at either eBay, Amazon or purchase from your local TPMS dealer. Use the hex/Allen wrench provided to remove the anti-theft screw and take of the sensor. Then use a small Phillip screw driver to take the cap marked “Easy Tire” off. Under the cap is the battery. Remove it and replace it with a new CR1632 battery. Depending on how long the battery was low you may have to reprogram the sensor

1. Open the sensor cap anti-clockwise.
2. Replace a new CR1632 battery and make sure positive pole upside.
3. Check the waterproof 0 -ring, replace a new one B if it is broken

• REPEATER / SIGNAL BOOSTER (OPTIONAL PART)
  • Recreational Vehicles, Tow Vehicles, Trailers and Tractor Trailer The Repeater/Booster is designed to amplify the signal from your TPMS system sensors. In situations where length, structure or electronic interference prevents your monitor from receiving a signal, the Repeater/ Booster amplifies the sensors transmitting distance. Some Diesel Pushers experience difficulties do to the number of electronic components in the engine compartment. As well as where sensors are shielded by bodywork etc. causing sensor signal strength to be reduced and where extremely cold temperatures may reduce sensor battery power. The optional signal Repeater/ Booster can be ordered separately and is available at your local dealer or distributor. The hard- wired booster should have 12V DC power when the vehicle is moving.
• REPEATER / BOOSTER SINGNAL INDICATION
  • Repeater / booster signal indicator (P) will be displayed on monitor screen when repeater is connected with power supply (12~24V) and received   signals from sensors. If there is no signals from sensors over 15mins, the signal indicator will be off.
• PLACEMENT INSTRUCTIONS
  • A booster/ signal repeater (should be ordered separately) could be used for trailer exchange. It is required to install a booster for each trailer. For towing truck it is recommended to install the booster at the rear part of the vehicle. For trailers, it is recommended to install the booster in front of each trailer.

Hint : Most people Install them Into their aft compartment or closet In the coach and wire It Into the compartment or closet light. By placing It on the coach you receive the advantage of the Repeater Booster even when your tow vehicle Is not connected. INSTALLATION INSTRUCTIONS Be sure to wire the Repeater Into a 12V power source that will be “on” during vehicle operation. The Repeater will be on as soon as It Is connected to power. The red light stays] on when power Is connected

• The center button that lights up also serves as a reset button. INSTALLATION OF THE REPEATER ONLY REQUIRES IT BEING CON NEC TED TOA 12V POWER SOURCE AND GROUND-WHEN THE RED LIGHT COMES ON IT IS FUNCTIONING.
• REPEATER/BOOSTER ALERTS
  • High/Low Pressure and Fast Leak Alerts When the sensor detects high/low-pressure abnormalities and rapid leaks, It will send an alert to the Repeater/Booster immediately. The audible alarm will be on together with the flashing red light. Press any button on the monitor to turn off the alarm. However, the flashing red light will continue until the image Is resolved. The system Is set-to alarm If you lose more than 7.25 psi In a minute.
• High-Temperature Alert
  The monitor has a fixed temperature alarm at 158 dig F/70deg C. The sensors sand the temperature readings to the monitor. If the temperature la above 158 dig F/70deg c, an audible alarm will be on together with the flashing red light. Presa any button to turn off the audible alert. The red light will remain on until the Issue Is resolved.
