Initial Use

New batteries are shipped uncharged from the factory.

Charge a new battery for 5 hours before initial use. The

maximum battery capacity and performance is achieved

after three full charge/discharge cycles. If you notice the

battery power runs low, please recharge the battery.

Applicable Battery Packs

To reduce the risk of injury, charge only the battery speci-

fied by the ma nufa ctur er. Other b atte ries m ay burst,

causing bodily injury and damage.

Caution:

1. To avoid risk of personal injury, do not dispose of bat-

teries in re!

2. Dispose of batteries according to local regulations (e.g.

recycling). Do not dispose as household waste.

3. Never attempt to disassemble the battery.

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 cut off the power supply or remove the battery

when charging a battery.

4. Never charge a battery that is wet. Please dry it with a

soft cloth prior to charge.

5. The battery will eventually wear out. When the operat-

ing time (talk-time and standby time) is noticeabl y

shorter than normal, 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 (Ni-

MH & Ni-Cd batteries: 3 months; Li-Ion & Li-polymer

batteries: 6 months), to avoid reducing battery capacity

due to over-discharge.

3. When storing your battery, keep it in a cool and dry place

under room temperature, to reduce self-discharge.

required. Once beyond the communication range, the

radio will automatically sound alert.

Scan

Each channel can be set with one scan list, and each

list contains up to 32 channels. Scan lists on different

channels can be the same or different. Scan proceeds

according to the scan list assigned to a channel where

scan starts.

◆

Scan Type

1. Normal Scan

Allows users to scan the activity on each channel with

squelch mode match in the scan list.

2. Vote Scan

It applies to multi-frequency simulcast systems, which

is suitable for places with abundant frequency resource.

In this system, the repeater allows for wide coverage.

A typical multi-frequency simulcast system comprises a

set of scattered base stations that are transmitting at the

same frequency. And the radios in this system are typically

congured to transmit at the same frequency and receive

at different frequencies. The radio scans the frequencies

of these base stations and selects the closest base station

to communicate through voting algorithm.

◆

Scan Start

The radio will sound a programmable alert when scan

starts. During scanning, the LCD will display “ ” and the

LED flashes green. The corresponding channel number
