door
Close the battery door
WARNING There is a danger in which incorrectly placing the battery can cause an explosion. Always make
sure the radio is switched off before installing or changing the battery. Replace only with the same or
equipment type. Use ONLY with lithium 4.2V 1050mAH rechargeable battery. Contact your local retailer for
more information.
When the battery power is low, Red LED will flash, please charge it or replace it with a new one.
To charge the battery

1.
2.
3.
4.
Plug the adaptor output into the socket on the back side of charger.
Plug the adaptor in the main.
The Desktop charger can charge both the radio and a separated battery.
LED indicates the charging condition: one for radio unit, and another for separated battery.
If there is no battery in cradle, LED is RED. While Radio unit or battery is placed into the cradle, the
LED will becomeGreen. After charging fully, the LED will become RED.
NOTE
1. To maintain the battery life of your radio it is recommended that you only charge the battery when needed.
Overcharging the battery will reduce performance.
2. Ensure that the unit is turned off before charging.
3. Remove batteries before storing your radio for extended periods. Batteries corrode over time and may
cause permanent damage to your radio.
4.Please use the specified power adaptor within the same rating.
2. INSTALLING THE BELT CLIP
Rotate the clip to be suitable for Horizontal or Vertical mounting on the belt.

Page 6 of 10
4. RESET
Remove the battery pack for two minutes and insert it again. Any preferred setting will be cleared, the radio
will be in initial condition with default values.
5. TALK TO ANOTHER TRANSCEIVER
1. To make a call, press and hold PTT button, then speak into the microphone using your
normal speaking voice.
While transmitting, LED becomes RED.
2. When finished speaking, release the PTT button to allow other radios to respond.The radio will
automatically switch to receive mode.
Once you have received voices from other radio(s), LED will become constant Green, otherwise green LED
will flash in intervals.
NOTE You can only communicate with another transceiver that is on the same channel and using the same
CTCSS/DCS code as your radio.
NOTE For best transmission speak about 3-4 cm away from the microphone and after pressing PTT button,
leave a short pause before speaking.
NOTE When the battery voltage becomes too low, transmitting stops and red LED flashes. Please refer to
auxiliary function “Low Battery Warning”.
6. SELECT A CHANNEL OR CTCSS/DCS
The transmitter and receiver must be on the same channel using the same CTCSS code in order for you to
communicate with another party.
This feature allows you to utilize a less often-used range of CTCSS codes within a main channel to avoid
congestion on the main channel and filter out unwanted noise and static. There are 38 CTCSS codes for each
main channel.
IMPORTANT: The channels must be programmed, using the PC software provided, before using the
device / transmitter for the first time. Only then will the user be able to choose between the available
channels.
To select channels
Press CH+ or CH- to change channels.
To check transmitter and receiver are using the same channel:
Press PTT button. The other party should hear a distortion noise.
NOTE The noise can be loud. Please place earphone a certain distance away from ear when checking to
avoid discomfort.
NOTE By pressing CH+ or CH- button once, a voice prompt will indicate which channel is currently being
used, e.g., “one, two,…”.
By pressing CH+ or CH- button again, you will Increase or Decrease the channel. Voice prompts will
indicate the new channel set.
NOTE To communicate with other units that do not have CTCSS code capability, switch your unit to the same
channel and set the CTCSS code to“0”.

AUXILIARY FUNCTIONS
TIME-OUT TIMER (TOT)
Time-out Timer is to prevent the use of the same channel for too long and the radio from energy waste due to
continued transmission.
If the radio continuously transmits signals for a period over the preset limit (set by your dealer, max time is 5
minutes), the transceiver will stop transmitting and a beep will sound. To stop the tone, release the PTT button.
Press the PTT button again to resume transmission.
Battery Save
This function minimizes the amount of power used when a signal is not being received and no operations are
being performed (no keys are being pressed).
While the channel is not busy and no operation performed for 10 seconds, Battery Save turns ON. When a
signal is received or an operation is performed, Battery Save turns OFF.
LOW BATTERY WARNING
Low Battery Warning alerts you when the battery needs to be recharged.
While transmitting, if power of the battery goes below a pre-determined value, the red light will flash, a tone
sound, and the radio will stop transmitting. Please replace or recharge the battery.
MONITOR
The squelch circuit on the radio automatically mutes the speaker when there are no signals, eliminating
background noise. Press and hold "CH UP" key to manually deactivate the squelch mechanism. This
operation is especially useful for adjusting volume level or receiving a weak signal.
CTCSS & DCS
Some channels may have pre-programmed CTCSS/DCS tones. A CTCSS/DCS tone is a sub-audible signal,
which allows you to ignore (not hear) calls from other parties using the same channel.
When you receive a signal that has a tone different from the one set up in your radio, you will not hear the
signal. Likewise, signals that you transmit will only be heard by parties whose CTCSS/DCS tone matches the
tone set up in your radio.
NOTE Although using channels set up with CTCSS/DCS tones enable you to avoid hearing those unwanted
calls, it does not mean your calls will be private.
