Safety Precautions

To use this product safely, please read this IFU carefully and understand it. Please be sure to follow the instructions in this manual.
To avoid a disaster when using this product, you must know in advance the factors that may be dangerous. However, it is difficult to predict all potential dangers.
Therefore, warnings about security are defined and described in this manual.

WARNING!

If you do not follow the instructions in this symbol, you are warned that there is a risk of property damage, injury, or death. Because it is especially important, it is described below as “safety precautions and warnings”

Safety Warnings

WARNING! This product features a layer of soft air floating beneath the patient’s body. Therefore, do not use it when patients need to undergo cardiac resuscitation.
WARNING! Use this product with your doctor or specialist when using this product. In addition, if the body feels abnormal during use, or the symptoms are worse, or there is a risk of accident, stop using it immediately and consult an expert.
WARNING! When you move to a stand position or get out of the cushion, be sure to ask someone else for assistance, otherwise there is a danger of falling.
WARNING! Smoking is not allowed on the cushion and may cause a fire.
WARNING! Please do not bundle the air outlet or press it under the cushion. When the blower tube is bent or compressed, air may not enter the air mattress and may not achieve the desired results.
WARNING! Do not use the air pump in a damp place. Do not use in or around water or urine, which may result in electric shock or malfunction. Avoid direct sunlight.
In hot and humid places, keep it away from the wall or above 55cm to avoid moisture retention.
WARNING! Please do not remove the screw of the air pump to open the casing and repair it yourself; it may cause electric shock or malfunction.
In addition, the modification of the air pump without our consent may pose a serious safety hazard. Never let customers modify the air pump.
WARNING! If you do not use the air pump for a long time or need to clean the air pump, be sure to unplug the power cord from the outlet. If not it may cause accidents, electric shocks, and malfunctions.
WARNING! Please do not pull on the power cord of the air pump, do not damage the power cord, and do not clip the power cord to the door. When removing the plug from the socket, be sure to hold the power plug and pull it out to avoid electrical accidents and fire.

User instructions

Step 01 Place the cushion on the chair

N.B. Actual cushion may look different to that shown in the image
Step 02:

Hang the hooks of the air pump on the chair frame or put on a nearby platform if the chair is not moving
Connect the air pipes using the quick connector to the side of the pump
N.B. Actual pump may look different from the above image

Step 03

Turn On the power
Adjust the Pressure
Adjust the Function

Power: Press this button to turn the pump on and off.
Pressure: Press this button to cycle through the 3 pressure settings
- LOW = 20mmHg
- MEDIUM = 40mmHg
- HIGH = 60mmHg
Static: Press this button to cycle through the Static & Alternate settings:
- The default setting is 6 min alternating cycle. You can select to put the pump into a static function for 10 min or 20 min.
- After the selected time has elapsed, the pump automatically defaults to 6 min alternating cycle
Battery Indicator: This shows the level of charge currently in the battery.
- When all 4 lights are illuminated green, the battery is fully charged.
- As power is used, the number of lights illuminated reduces.
- When there is only 1 light left, it is time to charge the battery.
Charging Indicator: When the power adapter provided with the pump is connected to the pump and a suitable power supply, the charging indicator symbol is illuminated green.

As the battery charges the lights on the battery symbol illuminate gradually from no lights to 4 lights and then all lights extinguish and the sequence starts again until the battery is fully charged.
When the battery is fully charged, all 4 lights on the battery symbol remain illuminated constantly.
Once the battery is fully charged remove the power adapter from the pump, although there is a safety feature to prevent overcharging.
Step 04: Terminate the operation of the device
When you do not need to use the device, turn off the power to save the charge in the battery.

---|---|---|---

NOTE 1 At 80 MHz and 800 MHz. the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcasts and TV broadcasts cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the model P08M is used exceeds the applicable RF compliance level above, the model P08M should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the model P08M.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between portable and mobile RF communications equipment and the model P08M
The model P08M is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the model P08M can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the model P08M is recommended below, according to the maximum output power of the communications equipment.
