Features and Operations
Power Level
Description
Power Level allows you to set the TX power level. High power can extend
the signal coverage, enabling you to communicate with farther radios.
Generally, we recommend you to adopt low power for battery saving.
Operation
Press the programmed
Adjust Power Level
key to toggle the power
level between high and low. When you switch to high power, a high-
pitched tone sounds; when you switch to low power, a low-pitched tone
follows.
Covert Mode
Description
Covert Mode allows you to disable all the visible or audible indications
programmed by your dealer, such as the LED indicator, vibration and
tones, for communication in covert situations. This feature is mainly used
in special missions.
If an audio accessory is connected to the radio, the
radio will output the voice and alert tones via the audio
accessory when the Covert Mode is enabled.
Operation
Press the programmed
Covert Mode
key to enable or disable this
feature.
Note
Time-out Timer (TOT)
Description
This feature is to prevent any user from occupying a channel for an
extended period and to avoid radio damages due to overheat.
Operation
If the TX time (60s preset by dealer) expires, the radio will automatically
terminate transmission and keep beeping. To stop beeping, please
release the
PTT
key. You must wait for a certain time period (preset by
your dealer) before you can hold down the
PTT
key to transmit again.
Busy Channel Lockout
Description
Busy Channel Lockout can prevent radio user from interfering other
transmitting radio users on the same channel.
Operation
When the channel is busy, the radio will beep when you hold down the
PTT key to transmit, indicating the channel is busy. You can hold down
the
PTT
key to transmit when the channel is free.
