Battery information

Caution
In order to avoid damage to the battery, only use the charger provided. The supplied charger is an ‘intelligent’ charger and has automatic and over- protect functions built in. Do not short-circuit the battery pack or dispose of in fire. The optimal charging temperature is between 10°C ° and 35 C. When charging in temperatures below 10° C there may be a leakage of electrolyte which will damage the battery. If charging above 35°C, battery performance will be reduced.

Battery Charging
Connect the AC adaptor to the charger. The red LED will light up. Place the battery or the radio with battery attached into the charger (check that the battery is properly in place). The red light will begin to flash – indicating that charging is in progress. The LED will turn green when the battery is fully charged. (see illustration 1)

Function and Operation

Basic Settting
Radio ID
Each radio can be assigned with an ID number, which is useful and can be identified by other users to place an individual call/group call or to send text info etc. ID Range: 1-16776415.
Noted: This function is valid only in digital mode.

Language Selection
Users can select English or Chinese as display language and voice prompt language.

SQ (Squelch Level)
Squelch level can be programmed from level O to level 9, receiving sensitivity is the lowest when set in level 9.

Battery Save
If this function is programmed by your dealer, the transceiver will automatically switch to battery save mode when there is no receiving and no operation for more than 10 seconds. When the transceiver receives an incoming signal or is used to transmit, the battery save mode switch off automatically. Battery Save can be programmed
ON/OFF by PC software programming.

Time-out Timer (TOT)
The purpose of the Time-out-Timer is to prevent any caller from using a channel for an extended period and avoid any damage caused by long time transmission. Once a continuous transmission exceeds the preset time(programmable by dealer), the transceiver will automatically stop transmitting and emit a warning tone until the PTT is released. Time-out Timer range: 30-600s, steps: 30s, default: 180s

VOX Function
VOX can be programmed ON/OFF by PC software programming or activated/disabled by a pre-programmed key, VOX ON allow users to place a voice-activated hands- free call on the pre-programmed channels. Whenever the microphone detects voice, the transceiver will automatically transmit and stop transmitting when voice disappear, or pre-programmed TOT time expires.
VOX Level Range: 0-9
VOX Delay Time: 1-4s

Alert Tone Settings

1. Power ON Tone: ON/OFF selective, the transceiver will emit tone “Deng Deng Deng .. ” when switched ON/OFF;
2. Lower Battery Alert Tone: ON/OFF selective, transceiver will emit alert tone “Deng Di Deng .. ” if the power is lower than preset value, users should charge the battery or replace with a new battery in time, or the transceiver will stop transmitting if users continue using it.
3. Keypad Tone: ON/OFF selective.
4. Digital Calling Tone: ON/OFF selective, in digital mode transceiver will emit an alert tone “Deng” automatically once after PTT pressed, this is used to alert its in digital mode and also transmitting is ongoing.
5. Channel Voice Prompt Tone: ON/OFF selective.

Channel Information

1. Zone Name
   Users can input new name for zone 1 and zone 2, the name can be programmed as number, symbol, English letter and Chinese character up to 9 digits.
   Users can press the corresponding button to add zone, delete zone and switch between zones.

2. Channel Name
   Users can input new name for each channel, the name can be programmed as number, symbol, English letter and Chinese character up to 9 digits.

3. General Part
   RX/TX Frequency: Users is able to input/change RX/TX frequency for each channel, and the frequency must be consistent with the frequency step rule and within frequency range.
   Working Mode: Digital/analog mode is selective for each channel. Output Power: High/Low power selective for each channel. Transmitting Limit
   Always Allow: Transmitting is always allowed.

   There are maximum 128 transmitting contacts for users to select, each transmitting contact can be programmed as individual call, group call or all call.
   Dual Capacity Direct Mode (DCDM)
   Dual Capacity Direct Mode (DCDM) feature supports two simultaneous subscriber transmissions within a 12.5 kHz channel bandwidth for Direct Mode transmissions. The radios within the same group must use the same timeslot so that the group using timeslot 1 does not interfere with the group using timeslot. When a 12.5 kHz RF channel is configured for dual capacity direct mode, both timeslots are available for independent and simultaneous radio call conversations.
   RX Group List: This option is to configurate receiving channel list to the current channel. When matched calling group ID from the list detected, the receiving transceiver will open the speaker to receive audio. Noted: This function is valid only in digital mode.
   Voice Encryption: This function allows user to program voice encryption code to the current channel, conversation is allowed between radios only when same encryption code are programmed.
   Code range: OFF, 0 – 65535.Time Slot Selection: This function is used for dual capacity direct mode(DCDM) and working through repeater, each digital channel can be configurate with time slot 1 or time slot 2.

5. Analog Part
