Battery Tips

1. When charging your battery, keep it at a temperature among 5 ℃ - 40 ℃ .
Temperature out of the limit may cause battery leakage or damage.

2. When charging a battery attached to a radio, turn the radio off to ensure a full charge.

3. Do not return fully charged batteries to the charger for an “extra boost”. This action
will significantly reduce battery life.

4. Do not return a battery to the charger before the battery power runs low. This action
will significantly reduce battery life. Never take the charger as a stand for your radio.

5. Never charge a battery that is wet. Please dry it with soft cloth prior to charge.

6. The battery will eventually wear out. When the operating time (talk-time and standby
time) is noticeably shorter than normal performance, it is time to buy a new battery.

To Prolong Battery Life

1. Battery performance will be greatly decreased at a temperature below 0℃. A spare
battery is necessary in cold weather. The cold battery unable to work in this situation
may work under room temperature, so keep it for later use.

2. The dust on the battery contact may cause the battery cannot work or charge. Please
use clean dry cloth to wipe it before attaching the battery to the radio.

Battery Storage

1. Fully charge a battery before you store it for a long time, to avoid battery damage due
to over-discharge.

2. Recharge a battery after several months’ storage (Li-Ion & Li-polymer batteries: 6
months), to avoid battery capacity reduction due to over-discharge.

3. Store your battery in a cool, dry place under room temperature, to reduce
self-discharge.

CTCSS/CDCSS

Set up talkgroups with unique CDCSS/CTCSS to prevent unwanted conversations on the
same frequency.
If CTCSS/CDCSS is set on the current channel, CTCSS/CDCSS match is required for the
radio to unmute to an incoming signal. If CTCSS/CCSS is not set, the radio can receive
calls from all users operating on the same frequency. Your dealer may set
CTCSS/CDCSS for some channels.
This feature does not mean that your conversation will not be heard by others. Radios that
set with the same CTCSS/CDCSS, or no CTCSS/CDCSS, can receive from you.

Battery Save

This feature, when no signal is received or no operation is made, can lower battery
consumption.
Once the radio detects no activity on the channel and no operation performed (no key
