Battery Informationy/Antenna and Other Accessories
Charging the Battery
The battery is not charged in factory, charge it before use. When first charging the battery after
purchase or extended storage (more than 2 months), battery capacity is lower than its normal capacity.
Repeating the charge/discharge cycle two or three times, its capacity will recover to normal.
Notes:
Do not continue charging the battery if it is already fully charged and take the battery away from the
charger, otherwise, the battery life will be shortened or damage may be caused.
Turn the radio power OFF before charging. Using the radio while charging its battery will interfere
with correct charging.
When the battery operation time decreases even though it is fully and correctly charged, that means
the battery life is over, please replace it with a new battery.
Do not complete the battery terminals (short circuit ) or dispose of the battery by fire.
Never disassemble the battery cover.

Place the battery or the radio with a battery into the charger.
* Make sure the battery is well connected with the charger
connectors.
* When rapid charging starts, red LED glows; when
charging is complete, green LED glows.

Rapid Charger
General
1. Smart IC controls charge/discharge process, automatically adjusting its current according to the
battery state.
2. Performance is stable, not susceptible by the environment.
With multi-protections, preventive from over-charge.
3. Charge/discharge process is indicated with corresponding LED colors and states.
Features
For battery: 7.2V Ni-Cd & Ni-Mh rechargeable battery
Operation temperature: 0℃-48℃
Fast charge current: 720mA+-5%
Top-off charge current: 90mA
Pulse-Trickle charge current: 25mA

Discharge current: 350mA
Discharge termination voltage: 6.0V
Operation:
Charge: Connect the charger to the power source, and place battery in the charger cup, making sure
they connect well. Red LED flashes for 3 seconds and then solidly glows, now the charge enters the
fast charge phase. When the charging is over, green LED glows.
Discharge:In order to avoid battery burning and memory effect, this charger is designed with
discharge feature. Discharge procedure is the following:
Place the battery in the cup, and red LED glows. Press the discharge button, red LED flashes, and now
discharge begins. Charge begins at the end of discharge.
Notes:
HYT adaptor is recommended to use to avoid damage to the charger circuit.
Do not operate in high temperature or corrosive conditions.
Do not pull/plug the adaptor or the battery in the charge process to avoid interfering with the charge
phases.
The battery is recommended to take out after the green LED glows for 120 minutes for the protection
of the battery chemical materials.
To eliminate battery memory effect, Ni-Cd battery is recommended to discharge twice per month.
Additional Remarks:
It’s a normal phenomenon that the red LED flashes without the discharge button pressed after the
battery is placed in the cup. This is a protection in the condition of too low battery voltage or too high
temperature, and now the pulse-trickle current is 25mA. When the voltage or temperature recovers to
normal level, red LED stops flashing, and fast charge begins.

Auxiliary Functionsy Functions
Time-out Timer
Time-out Timer is used to prevent one from using the same channel for a long time and to prevent the
radio from damage due to continuous transmission.
If the transmission exceeds preset time (it’s set by your dealer, max. time is 10 minutes),
transmission will be stopped and a beep will sound. To stop the alert tone, release PTT. Press PTT
again to transmit.
Battery Save
This function minimizes the amount of power used when no signal is being received and no operation
is being performed (no key is being pressed, and no switch is being turned).
When there is no activity on the channel and no operation is performed for 25 seconds, Battery Save is
turned ON. When a signal is received or an operation is performed, Battery Save is turned OFF.
Low Battery Warning
Low Battery Warning alerts you to recharge or replace the battery..
During transmission, when the battery voltage goes below a preset value, red LED will flash. When
the alert tone sounds, the radio stops transmitting. Please replace or recharge the battery.
Monitor
Press and hold "MONI" key to monitor activities on the current channel. This operation is especially
useful for adjusting volume level or receiving a weak signal.
The green LED glows while the "MONI" key is held down.
CTCSS & CDCSS
CTCSS/CDCSS allows you to ignore unwanted calls from other parties using the same channel.
When CTCSS/CDCSS is set, the user can only receive the calls on the same channel with same
CTCSS/CDCSS.
Note: Although using CTCSS/CDCSS enables you to avoid hearing unwanted calls, it does not
mean your calls will be private.
TTS (Two-Tone Signaling)
TTS is used to open or close the squelch. It includes Two-Tone call and group call, which is
programmed by the dealer.
Receive
If a signal containing the correct tones is received, the squelch is opened and you can hear the call, and

the following events happen:
◇Orange LED flashes in standby mode; green LED glows in receive mode; red LED glows in
transmit mode.
◇If Tone for TTS has been programmed, an alert tone will sound when the correct tones are
received.
◇If Tanspond for TTS has been programmed, a tone for acknowledgement will be returned to the
caller.
◇Press MONI key again to close the squelch, the speaker is muted.
Transmit
◇Holding down PTT and MONI keys simultaneously will transmit preset tones .
◇Red LED solidly glows in transmitting.
◇The radio will keep transmitting until the tones are completely sent. When the tones are sent, the
squelch is opened, and now, if no signal is received, orange LED will flash.
◇Pressing MONI key again will close the squelch, and the speaker is muted.
Channel Scan (This feature is programmed by your dealer)
Turn Channel selector to the position “S”, the radio will automatically detect those channels which
have been programmed as scan items in channel 1-15 (your dealer can set any channel as scan item or
non-scan item). When any activity is detected on one channel, the radio will stop on the active channel
for communications.
Priority channel scan
Any programmed channel may be set as the priority channel. The radio will detect the priority channel
periodically while stopping on a non-priority channel. When there is any activity on the priority
channel, the radio will turn to the priority channel for communications.
Scan Revert channel
The Scan Revert Channel feature sends you to the right channel while initiating a call during channel
scan. Press [PTT], the radio stops scanning and transmits on the revert channel.
Revert channel can be programmed by your dealer.
Busy Channel Lockout
If the channel you choose is set by your dealer as "busy channel lockout", and this channel is being
used by other users, press PTT, the radio generates a beep and will not transmit the signal. To stop the
beep, release PTT. When this channel is free, press PTT to transmit.
