7. Supplementary Features
7.1 VOX
When the voice detected by the microphone reaches the value to trigger the transmission, the radio automatically
transmits the voice without the
PTT
key pressed. The VOX Gain feature preprogrammed by your dealer is used to
control the sensitivity of microphone transmission.
Press the preprogrammed
VOX
key to enable this feature.
7.2 Scan
The Scan feature allows you to listen to activities on other channels, keeping track of your team members.
Press the preprogrammed
Scan
key to enable this feature.
With this feature enabled, the radio scans according to the scan list preset for the current channel. The LED
indicator flashes orange slowly. When detecting activities on a channel, the radio stays on the channel and the
LED indicator glows green.
7.3 Squelch Level
The squelch level refers to the squelch threshold required for the speaker of the radio to be turned on. The higher
squelch level requires stronger signal.
Press the preprogrammed
Adjust Squelch Level
key to adjust the squelch level.
7.4 Scrambler
The Scrambler feature allows the radio to invert the frequency spectrum of transmitted audio signals. Only the
receiving radio with the same Scrambler settings can restore the audio signals. This prevents eavesdropping and
ensures communication privacy.
Press the preprogrammed
Scrambler
key to enable this feature.
7.5 Monitor
The Monitor feature allows the radio to receive more signals including weak signals, and helps you to recognize
weak voices in the speaker.
Press the preprogrammed
Monitor
key to switch between monitor squelch mode and receive squelch mode.
