Switch the radio set off, then insert the plug of the headset into the speaker/microphone jack.
Switch the radio on again. The VOX headset (whisper VOX) is now ready for use.
CTCSS/CDCSS (factory setting: channels 9 - 15 with CTCSS/CDCSS, see table p.16)
The radio set is equipped with two pilot tone processes (CTCSS and CDCSS) that permit to
address specific individual radio sets or groups or to receive only calls from the latter.
Important notes: Make sure that you and your partner station(s) use the same pilot tone process
and the same CTCSS tone or the same digital code!
Channel scan (channel 16)
The automatic channel scan permits to find active channels quickly. It scans independently all
of the 15 channels and stops as soon as a signal exceeds the squelch threshold.
To start the channel scan, adjust the channel selector to channel 16 (announcement: scanning
ON), the red status LED flashes. If a signal is received on the adjusted channel, the green status
LED lights up, the radio set remains adjusted to the corresponding channel until the signal finishes.
Afterwards, the scan starts again, the red status LED flashes again.
For switching off the channel scan, adjust the channel selector to another channel (e.g. channel 15),
the announcement scanning OFF  15 sounds.

VOX function/phonetic transmission
Two operating modes are available:
Whisper VOX (factory setting: ON) when using a headset which is available as optional accessories
and VOX function for the internal microphone. (The VOX function enables transmission without
pressing the PTT button: Voices/noises that hit the microphone thus switch on the transmitter of
the radio set.)
Note: Only one of the two VOX functions can be activated: if you want to use the VOX for the
internal microphone you have to deactivate the whisper VOX via the software which is available
as optional accessories.
VOX sensitivity (factory setting: level 1)
Nine sensitivity levels are available (level 1: highest sensitivity, level 9: lowest sensitivity).
VOX dwell time (factory setting: 2 sec.)
This function permits to define the time over which the transmitter is still active after the end of
the announcement (0.3 to 5.0 sec.).
Scrambler
Speech scrambling prevents that your transmission can be tapped without further auxiliaries by
unauthorized persons.
Note: Enable this feature for all devices involved.
