Chapter 2. Charging the Battery

Charging the Battery Pack
The Li-ion battery pack is not charged at the factory; please charge it before use. Charging the battery pack for the first time after purchase or extended storage (more than 2 months) may not bring the battery pack to its normal maximum operating capacity. The best operation will require fully charging/ discharging the battery two or three times before the operating capacity will reach its best performance. The battery pack life may be depleted when its operating time decreases even though it has been fully and correctly charged. If this is the case, replace the battery pack.

Charger Supplied
Please use the specified charger provided by our company. Other models may cause explosions and personal injury. After installing the battery pack, and if the radio displays a low battery with a voice prompt, please charge the battery.

Use Caution with the Li-ion Battery

• Do not short the battery terminals or throw the battery into a fire. Never attempt to remove the casing from the battery pack, as our company cannot be held responsible for any accident caused by modifying the battery
• The ambient temperature should be between 5℃-40℃ (40˚F – 105˚F) while charging the Charging outside this range may not fully charge the battery.
• Please turn off the radio before inserting it into the It may otherwise interfere with correct charging.
• To avoid interfering with the charging cycle, please do not cut off the power or remove the battery during charging until the green light is battery
• Do not recharge the battery pack if it is fully charged. This may shorten the life of the battery pack or damage the battery
• Do not charge the battery or the radio if it is Dry it before charging to avoid damage.

WARNING: When keys, ornamental chains, or other electric metals contact the battery terminal, the battery may become damaged or injure a human. If the battery terminals are short-circuited it will generate a lot of heat. Take care when carrying and using the battery. Remember to put the battery or radio into an insulated container. Do not put it into a metal container.

How to Charge

• Plug the AC adaptor into the AC outlet, and then plug the cable of the AC adaptor into the DC jack located on the back of the charger. The indicator light blinks orange and is then ready to charge a battery.
• Plug the battery or the radio into the charger. Make sure the battery terminals are in contact with the charging terminals. The indicator light turns to red— charging begins.
• It takes approximately 2-5 hours to fully charge the battery. When the lamp lights green, the charging is completed. Remove the battery or the radio unit with its battery from a socket.

When charging a radio (with battery) the indicating lamp will not turn green to show the fully charged status if the radio is powered on. Only when the radio is switched off will the lamp indicate normal operation. The radio consumes energy when it is powered on, and the charger cannot detect the correct battery voltage when the battery has been fully charged. So the charger will charge the battery in constant voltage mode and fail to indicate correctly when the battery has been fully charged.

LED Indicator

NOTE: Trouble means the battery is too warm, the battery is short- circuited or the charger is short-circuited.

How to Store the Battery

1. If the battery needs to be stored, keep it in the status of 80% discharged

Chapter 5. Basic Operations

Power on the radio

• Turning the unit on
  To turn the unit on, simply rotate the Volume/Power knob clockwise until you hear a “click”. If your radio powers on correctly there should be an audible double beep after about one second and the display will show a message or flash the LCD depending on settings for about one second. Then it will display a frequency or channel. If the Voice prompt is enabled, the voice will announce “frequency mode” or “channel mode”.

• Turning the unit off
  Turn the Volume/Power knob counterclockwise until you hear a “click”. The unit is now off.

Adjusting the volume
To turn up the volume, turn the volume/power knob clockwise. To turn the volume down, turn the Volume/Power knob counterclockwise. Be careful not to turn it too far, as you may inadvertently turn your radio off. By using the monitor function, enabled from the [FM broadcast/Monitor] key below the PTT, you can more easily adjust your volume by adjusting it to the un-squelched static.

Main Band/Sub Band Select
In standby mode, press the [A/B] key to switch between A (upper) and B (lower) displays. The frequency or channel on the selected display becomes the active listening and transmitting frequency or channel. To save frequencies to channel memory you must be on the A display.

VFO/Channel Switch
Press the [VFO/MR] key to switch between VFO and channel display.

• In channel mode (MR), the channel number will be displayed on the right.
• In frequency mode (VFO), the ‘VFO’ will be displayed on the right.

Frequency (VFO) mode
In Frequency (VFO) mode you can navigate up and down the band by using the keys. Each press will increment or decrement your frequency according to the frequency step you’ve set your transceiver to. You can also input frequencies directly on your numeric keypad with kilohertz accuracy. The following example assumes the use of a 12.5 kHz frequency step.

Example. Entering the frequency 436.61250 MHz on display A

1. In standby mode, press the [VFO/MR] key to the frequency (VFO) mode.
2. Enter [4][3][6][6][1][2][5] [0] on the numeric keypad.

WARNING! Just because you can program in a channel does not mean you’re automatically authorized to use that frequency. Transmitting on frequencies you’re not authorized to operate on is illegal and in most jurisdictions a serious offense. However, it is legal in most jurisdictions to listen. Contact your local regulatory body for further information on what laws, rules and regulations apply to your area.

Channel (MR) Mode and Channel Selection

There are two modes of operation:

• Frequency (VFO) mode, and
• Channel or Memory (MR) mode.

For everyday use, Channel (MR) mode is going to be a whole lot more practical than Frequency (VFO) mode. However, Frequency (VFO) mode is very handy for experimentation out in the field. Frequency (VFO) mode is also used for programming channels into memory. In Channel (MR) mode you can navigate up and down the channel by using the keys or the encoder. Ultimately which mode you end up using will depend entirely on your use case. Press the [VFO/MR] key to switch the radio between VFO and Channel mode, and select Channel mode.

• Operation 1: Press the navigation key to select the channel.
• Operation 2: Input the channel numbers by the keyboard. For example, if you want to switch to channel 12, input [0][1][2] a total of 3 digits, and it will switch to channel 12.

When the voice prompt function is enabled, the corresponding channel will be broadcast by voice.

Making a call

NOTE : Press the [A/B] key to switch the main channel to the other channel if there are 2 channels shown on the display. In standby mode, press the [VFO/MR] key to switch between frequency (VFO) mode and channel (MR) mode.

• Channel mode call : After selecting a channel, hold down the [PTT] key to initiate a call to the current channel. Speak into the microphone with a normal tone. When making a call, the red LED is on.
• Frequency mode call: Press the [VFO/MR] key to switch to the frequency mode, input the working frequency within the allowable frequency range, and press and hold the [PTT] key to transmit on the current frequency. Speak into the microphone with a normal tone. When making a call, the red LED is on.
• Receive a call: When you release the [PTT] key, you can answer it without any action.
  When receiving a call, the green LED is on.

NOTE : To ensure the best reception volume, keep the distance between the microphone and the mouth at the time of transmission from 2.5 cm to 5 cm.

7. To exit out of the menu at any time, press the key.
8. All further examples and procedures in this manual will use the numerical menu shortcuts.

Scanning
The Radios feature a built-in scanner for the VHF and UHF bands. When in Frequency (VFO) mode it will scan in steps according to your set frequency step. In Channel (MR) mode it will scan your channels. At approximately three frequencies per second, it’s not the fastest scanner in the world, but it is nonetheless a useful feature to have at times.

Dual Watch is inhibited while scanning
To enable the scanner, press and hold the key for about two seconds. Press and hold the key to exit scanning mode.

Scanning modes
The scanner is configurable to one of three ways of operation: Time, carrier, or search, each of which is explained in further detail in their respective section below.

Setting scanner mode

1. Press the key to enter the menu.
2. Enter [2] [1] on your numeric keypad to come to scanner mode.
3. Press the k ey to select.
4. Use the keys to select scanning mode.
5. Press the key to confirm and save.
6. Press the key to exit the menu.

Time operation
In Time Operation (TO) mode, the scanner stops when it detects a signal, and after a factory preset time out, it resumes scanning.

Carrier operation
In Carrier Operation (CO) mode, the scanner stops when it detects a signal, and after a factory preset time with no signal it resumes scanning.

Search operation
In Search Operation (SE) mode, the scanner stops when it detects a signal. To resume scanning you must press and hold the key again.

Frequency scanning
This function can scan the frequency.

• In frequency mode, press the key for more than 2 seconds. The radio will start scanning the frequency according to the set frequency step.

• Press the key and the scan of DCS codes will start.

NOTES : The function cannot be activated when the radio is set in Channel mode. The Scan will start only when the receiving band detects a signal.

Manual Programming (Channels Memory)
Memory channels are an easy way to store commonly used frequencies so that they can easily be retrieved at a later date. The radios feature 999 memory channels that each can hold: Receive and transmit frequencies, transmit power, group signaling information, bandwidth, ANI/ PTT-ID settings, and a six- character alphanumeric identifier or channel name 1.

Frequency Mode vs. Channel Mode
In standby mode, press the [VFO/MR] key to switch between frequency (VFO) mode and channel (MR) mode.

These two modes have different functions and are often confused.

• Frequency Mode (VFO): Used for a temporary frequency assignment, such as a test frequency or quick field programming if permitted.
• Channel Mode (MR): Used for selecting preprogrammed channels.

Ex 1. Programming a Channel Repeater Offset with CTCSS Tone

EXAMPLE New memory in Channel 10: RX = 432.55000 MHz TX = 437.55000 MHz (This is a (+ 5) Offset) TX CTCSS tone 123.0

• Press the key to switch between menus.

• Press the [VFO/MR] key to set the radio to VFO mode, and the VFO icon is displayed on the right.

• [3][1] [1] [0] Deletes Prior Data in the channel (Ex. 10)

• [1][2] 123.0 Selects desired TX encode tone

• Enter RX frequency (Ex. 43255000)

• [3][0] [1][0] Enter the desired channel (Ex 10)
  RX has been added

• Enter TX frequency (Ex. 43755000)

• [3][0] [1][0] Enter the same channel (Ex 10)
  TX has been added

• Press the [VFO/MR] key to return to the MR mode and the channel number will reappear.

Ex 2. Programming a Simplex Channel with CTCSS tone

EXAMPLE New memory in Channel 10: RX = 432.6625 MHz TX CTCSS tone 123.0

• Press the key to switch between menus.

• Press the [VFO/MR] key to set the radio to VFO mode, and the VFO icon is displayed on the right.

• [3][1] [1] [0] Deletes Prior Data in the channel (Ex. 10)

• [1][2] 123.0 Select desired TX encode tone (Ex 123 CTCSS)
  Use to select the Upper display

• Enter RX frequency (Ex. 43266250)

• [3][0] ****[1][0] Enter the desired channel (Ex 10)
  A channel has been added

• Press the [VFO/MR] key to return to the MR mode and the channel number will reappear.

Repeaters Programming
The following instructions assume that you know what transmit and receive frequencies your repeater employs, and that you’re authorized to use it.

• Press the [VFO/MR] key to set the radio to VFO mode, and the VFO icon is displayed on the right.
• Use the numeric keypad to enter the repeater’s output (your receiving) frequency.
• Press the key to enter the menu.
• Enter [2][9] on the numeric keypad to get to the frequency offset.
• Press the key to select.
• Use the numerical keypad to enter the specified frequency offset. See the section called “29 OFFSET – Frequency shift amount” for details.
• Press the key to confirm and save.
• Enter [2][8] on the numeric keypad to get to the offset direction.
• Use the key  to select + (positive) or – (negative) offset.
• Press the key to confirm and save.
• Optional:
  • Save to memory, see the section called “Manual programming” for details.
  • Set up CTCSS; see the section called “CTCSS” for details.
  • Press the key to exit the menu. If everything goes well, you should be able to make a test call through the repeater.

NOTE : If you’re experiencing problems making a connection to the repeater, check your settings and/or go through the procedure again. Certain Amateur Radio repeaters (especially in Europe) use a 1750Hz tone burst to open up the repeater. To see how this is done with the radios, see the section called “1750Hz Tone-burst”. If you’re still unable to make a connection, contact the person in charge of the radio system with your employer or your local amateur radio club, as the case may be. If you for some reason want to listen to the repeater’s input frequency instead, press key momentarily and you’ll reverse your transmit and receive frequencies. This is indicated in the LCD on the radio with an R in the top row, next to the + and – for the offset direction.

VOX
This function allows hands-free conversations: just speak in the direction of the microphone and the communication will be automatically activated.

• In standby mode, press + 7. The screen will display “VOX”.
• Press the key to enter the function. Press the keys to turn off the VOX function or to select the VOX level (1-10), then press a key to confirm.
• To return to the standby mode press key.

NOTE : level 1 is the least sensitive while level 9 is the most sensitive. When the radio is in Scan or FM Radio mode, the VOX is not enabled.

Dual Watch
In certain situations, the ability to monitor two channels at once can be a valuable asset. This can be achieved in one of two ways. You can either have one receiver in your radio and flip-flop between two frequencies at a fixed interval (known as Dual Watch), or you can equip a radio with two receivers (known as Dual Receive or Dual VFO). The former method is cheaper to implement and far more common than the latter. The Radios feature Dual Watch functionality (single receiver) with the ability to lock the transmit frequency to one of the two channels it monitors.

Enabling or disabling Dual Watch mode

1. Press the key to enter the menu.
2.  Enter 7 on the numeric keypad to get to Dual Watch.
3. Press the key to select.
4. Use the keys to enable or disable.
5. Press the key to confirm.
6. Press the key to exit the menu.

Stopwatch timer

• In standby mode, press + 44. The screen displays “STOP WATCH”.
• Press to enter the function. Press the keys to enable (ON) the function, then press the key for confirmation.
• To return to the standby mode press key.

Using the stopwatch timer:
When this function is ON, press a key to start counting; Press the key again to re-start counting. To exit the function, stop the counting first, and then press the key.

DTMF
DTMF is an in-band signaling method using dual sinusoidal signals for any given code. Originally developed for telephony systems, it has proved a very versatile tool in many other areas. In two-way radio systems, DTMF is most commonly used for automation systems and remote control. A common example would be in amateur radio repeaters where some repeaters are activated by sending out a DTMF sequence (usually a simple single-digit sequence).

DTMF frequencies and corresponding codes

| 1209Hz| 1336Hz| 1477Hz| 1633Hz
---|---|---|---|---
697Hz| 1| 2| 3| A
770Hz| 4| 5| 6| B
852Hz| 7| 8| 9| C
941Hz| ***| 0| #| D**

The radios have a full implementation of DTMF, including the A, B, C, and D codes.

The numerical keys, as well as the , and, keys, correspond to the matching DTMF codes as you would expect. The A, B, C, and D codes are located in the , and keys respectively. To send DTMF codes, press the key(s) corresponding to the message you want to send while holding down the PTT key. If you have the keypad lock enabled on your radio, you can still send DTMF tones the regular way without having to unlock your radio.
