Key Assignment

Power-on Key Setting
The power-on key can be re-assigned to any of the following functions by programming.
Customers can select it by short pressing.
Kindly note: If long press around 3seconds, the radio would power ON or OFF.

• NONE
• Channel Scan
• Channel Lock
• Battery Indicator
• Squelch OFF
• VOX ON/OFF
• Channel Broadcast

None: None operation functions
Squelch OFF: When the squelch is turned on, no matter how setup, the speaker can be forcibly turned on in this mode to listen to any sounds on the channel. If there is no audio signal on the channel, listen to the background noise; if there is an audio signal, listen to the audio. Press the [Squelch OFF] key to cancel the squelch function.
Channel Scan: A listening method used to hear calls on all channels. Press the key programmed as [Channel Scan] , the radio will scan the channel numbers in the queue one by one on time. While scanning, the green light flashes. When a signal is received on a certain channel and the signaling type matches, the status indicator light stays green. Press this key again to exit scanning.
VOX ON/OFF: Press the key programmed as [VOX ON/OFF] to turn on or off the VOX. The VOX is invalid without plugging into headphones. If VOX is turned on, there is no need to press the call button, as long as the microphone of the radio detects a voice, it will automatically start transmitting to achieve VOX calls.
Channel Lock: Press the key programmed as [Channel Lock] to lock the current channel.
Channel Broadcast: Press the key programmed as [Channel Broadcast] to broadcast the current channel number.
Battery Indicator: When need to know the remaining power of the radio, press the programmed [Battery Indicator] button, and the status indicator light will indicate the battery power through different colors. Press thi s key again to exit the battery indicator function. Status indicators of different colors indicate different battery storage capacities: 70%-100% blue light is on, 50%-70% red and blue lights are on at the same time, and 30%-50% red light is on.

Basic Operations

Power ON/OFF

1. Power ON: Press and hold the power button for 2 seconds, two voice alerts “beep, beep” will be heard, the radio will flash blue light to indicate power on.
2. Power OFF: Press and hold the power button for 2 seconds, two voice alerts “beep, beep” will be heard, the radio with flash red and blue lights to indicate power off.

Volume Adjustment

1. Short press the [VOL+/ CH+] key to increase the volume level;
2. Short press the [VOL-/ CH-] key to decrease the volume level.

Channel Selection
If you enable the voice broadcaset function, the radio will broadcast the current corresponding channel number.
Long press the [VOL+/ CH+] key to increase the channel from CH1 to CH16; long press the [VOL-/ CH-] key to decrease the channel from CH16 to CH1.

Receiving
When radios receive any signal, the LED indicator will turn green, you can hear the calling.

Note: If the transceivers has set at higher squelch level, it may fail to heard the calling. If the LED indicator turns green but can not hear the calling, that means the signal is with matching carrier but dis-matching CTCSS/DCS.

Transmitting
Hold PTT to start transmitting. Please hold the microphone approximately 2.5~5.0cm from your mouth, and the speak into microphone in your normal voice to get the best timbre.
Note: The LED indicator will turn red when transmitting, release PTT to standby or receive callings.

Function and Operation

CTCSS/DCS
Allow the user to select a specific CTCSS/DCS code per channel via programming software.
If CTCSS/DCS has been set on the current channel, CTCSS/ DCS match is required for radio to unmute to an incoming signal.
If CTCSS/ DCS is not set, the radio can receive calls from all users operating on the same frequency.
Your dealer may program the current channel with CTCSS/DCS, to prevent unwanted conversation on the same frequency.
This feature does not mean that your conversation will not be heard by others. Radios with the same CTCSS/DCS can receive calls from you.

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: 30-240s, steps: 30s, default: 180s.

TOT Re-Key Time
When this function is activated, transmission will be prohibited until TOT Re- Key Time expires, even if you have pressed the PTT key.
Range: 0~60S.
Default: 0

TOT Reset Time
If the time interval between two transmissions is less than the TOT Reset Time, they will be deemed as a continuous transmission.
When this function is activated, the TOT continuous even after PTT is released unless the TOT Reset Time has expired.

Busy Channels Lockout (BCL)
When the BCL function is enabled, the transceiver will not transmit on a channel that is already in use, to avoid disturbing other transceiver using the same frequency, Press the PTT on the busy channels, the radio will sound an alert tone and turn back to the receive mode.
Carrier: If BCL is set on the current channel, press the PTT key while the channel is already in use, and the radio will sound beeps without transmission.
CTCSS/DCS: If CTCSS/DCS and BCL are set on the current channel, press the PTT key while the channel is already in use, and the radio will sound beeps without transmission.

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.

Low Battery Alert
The RED LED flashes and the radio sounds “Please change the battery” every 30seconds, to alert the user to recharge the battery or replace it with a fresh one when the battery power runs low.

Dual Standby Channel
Once the radio turns on dual standby function, it can receive other signal from another dual standby channel on the current channel. After receiving the signal from the dual standby channel, it will transmit at the received standby channel frequency within 5 seconds. If none operation after more than 5 seconds, it will transmit at the current channel frequency again.
Note: Turnning ON or OFF the dual standby function or designating second standby channel is editable through programming software
