Used to connect audio accessories.
Mini USB Port
Used to connect accessories such as programming cable, cloning cable and
switching power.
Initial Use
New batteries from the factory are not fully charged, so be sure to charge a new
battery for at least 5 hours before initial use. Three full charge-discharge cycles
would optimize the capacity and performance of your battery. When battery
power runs low, it is time to recharge or to replace the battery.
Applicable Battery Packs
Please only use the battery specified by the manufacturer. Other batteries may
burst, causing bodily injury and property damage.
Caution:
1. Do not dispose of the battery in fire!
2. Recycling and disposal of the battery shall comply with your local regulations.
3. Never attempt to dismantle the battery.

2. To avoid battery capacity reduction due to over-discharge, recharge a
battery after storing it for a certain period of time: 6 months for Li-Ion & Li-
polymer batteries.
3. Store your battery in a cool and dry environment at room temperature to
reduce self-discharge.
Charging the Battery
When the Status Indicator flashes red, and an alert tone sounds at intervals of
ten seconds indicating the battery power runs low, please charge the battery
immediately. Only use the charger specified by the manufacturer. The Charge
Indicator will indicate the charging progress.
Please follow steps below to charge the radio with switching power:
1. Plug the AC connector of the switching power into an AC outlet socket.
2. Plug the Mini USB connector of the switching power into the Mini USB port
at one side of the radio unit.
3. Make sure that the battery is in good contact with the switching power. The
charging process begins when the Charge Indicator at one side of the radio
unit glows orange.
4. When charging is completed, the Charge Indicator glows green. Then you
may remove the radio.
Status Charge Indicator of the Radio

Fully charged Solidly glows green
Battery Information
1. Charge the battery at a temperature among 5¡æ-40¡æ. Violation of the said
limit may cause battery leakage or even damage.
2. When charging the battery that is attached to a radio, turn the radio off to
ensure a full charge.
3. Never charge a wet battery or a wet radio with battery attached. Please dry
it with a soft cloth prior to charge.
4. The battery will eventually wear out. When the operating time of a fully
charged battery is noticeably shorter than its normal performance, you
need to buy a new one. Please replace it ASAP.
5. If the product shuts off automatically due to low battery, please charge the
battery soon, or the battery could suffer damage.
6. If you plan not to use the radio for a long time, please remove the battery
from it to avoid any unexpected damage.
7. Do not charge fully charged batteries for an ¡°extra boost¡±. This action
will significantly reduce battery life.
8. Do not insert the radio or battery into the charger when it doesn¡¯t need to
be charged, because continuous charging will shorten the battery life. Note:
Never use a charger to hold the radio.
To Prolong Battery Life
1. Battery performance will decrease greatly at a temperature below 0¡æ.
Therefore, a spare battery is necessary in cold weather. However, the
replaced battery that fails to function at a low temperature may work at
room temperature, so keep it in place for later use.
2. The dust on the battery contact may make the battery work or charge
abnormally. Please use a clean and dry cloth to wipe the contacts before
charging or attaching the battery to the radio.
Battery Storage
1. If you plan to store a battery for a long time, please fully charge it first to
avoid battery damage due to over-discharge.

zTalk Back
This option defines whether users can talk back on the channel where scanning
pauses.
Checked: When the radio is staying on a scanned channel, it transmits on the
scanned channel; when the radio is not staying on a scanned channel, it
transmits on a preset channel.
Unchecked: The radio transmits on the preset channel.

Note:
1. If you intend to switch between VOX and PTT functions, unplug the earpiece,
toggle the switch to VOX or PTT and plug the earpiece again.
2. After the above operations are completed, the radio takes approximately 2-
3 seconds to perform auto-detection until it operates normally. During the
detection process, do not handle the earpiece; otherwise, it may malfunc-
tion due to detection errors.
3. If the earpiece functions abnormally, please pull and plug it again as
instructed above.
4. You may select VOX levels according to the operating environment. Too
much noise and too high VOX level may cause the radio to transmit
continuously.
5. Use only the VOX earpiece specified by the manufacturer, and properly
plug it into the jack; otherwise, the VOX function may not work.
