Advanced functions
(can be programmed via PC)
CTCSS / CDCSS (analog mode only)
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 note:
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!

tables see page 18
PTT ID (analog mode only)
[factory setting: OFF]
A programmed DTMF tone sequence is used to control e.g. relays, repeaters or to signal an
incoming call.
Note:
Each channel can be assigned individually.
ID Code (digital mode, only)
[factory setting: OFF]
The ID code permits
to call specific individual radio sets (single call) or several radio sets (group
call).
Note:
Each channel can be assigned individually.
Busy channel lockout
[factory setting: OFF]
For reducing interferences during radio communication, a transmit lockout can be activated which
blocks the transmission when the channel is busy. When pressing the push-to-talk button, a beep
sounds, the status LED flashes green and the radio set does not start transmitting. The beep
finishes when the push-to-talk button is released.
When the green status LED is not illuminated anymore, the channel is again free and transmission
can be started.
VOX function/phonetic transmission
This function permits to send without activating the transmit key: Voices/noises that hit the
microphone thus switch on the transmitter of the radio set.
VOX sensitivity
[factory setting: level 6)
Nine sensitivity levels are available (level 1: lowest sensitivity, level 9: highest sensitivity).
VOX dwell time
[factory setting: 1 sec.]
This function permits to define the time over which the transmitter is still active after the end of
the announcement (0.1 to 2.0 sec.).
TOT automatic transmitter cutoff
[factory setting: 180 sec.]
A permanent transmission on one channel can lead to damages on the radio set. In case the
push-to-talk button on the radio set is actuated unintentionally (e.g. when transporting the device
in a toolbox), the function
T
ime
O
ut
T
imer avoids an unwanted permanent transmission. If the
duration of a transmission exceeds a specified time (30 - 600 sec.), a warning signal sounds and
the transmission is automatically interrupted. The warning signal finishes as soon as the push-
to-talk button is released. Afterwards, transmission can be started again by pressing the push-to-
talk button.
Adjusting the squelch
[factory setting: level 6]
For adjusting the squelch, 9 levels are available (level 1: very low signal strength (noise), level
9: high signal strength).
