Automatic transmission time boundary
The transmission time is limited each time to a time between 10 seconds and 990
seconds. After this time, the radio automatically changes to receive – before a
short indicator tot – time out timer is the automatic transmission turn off. Release
the transmission button! If one presses the transmission button again, the radio is
switched to transmit and the time surveillance begins again. This function is not
just used as a gabbling lock, but also for if the transmission button is inadvertent-
ly jammed and the equipment is continually on transmission. In both cases, bat-
tery power is saved and is ready to receive again after the given time. When run-
ning this function is turned off.
- For a turned off radio, hold the FUNC button and simultaneously switch
the radio on.
- Hold the FUNC button and simultaneously select the menu tot using the
UP L or DOWN M button.
- Release the FUNC button!
- Install the desired time in 10 second intervals using the UP L or DOWN M
button (can be repeated by a longer press or pressing oFF)
- Press the PTT button slightly to lock.
Transmission locking for an active channel
Since one can only be heard when transmitting to a free channel, the transmission
button can be locked when receiving a station (ind. BUSY).
This also avoids the inadvertent distortion of other stations.
When running this function is switched off.
- For switched off radio equipment, hold the FUNC button and simultaneously
switch on the radio.
- Keep the FUNC button pressed and simultaneously select the menu bCLO using
the UP L or DOWN M button – indicator oF for the turned off transmission
locking or on for active transmission locking.
- Release the FUNC button and install the desired function on or off using the
UP L or DOWN M button.
- Press the PTT button to lock.
Advice: If the transmission button is pressed by the switched on locking device
and occupied channel, the radio will not switch to transmission (ind. bSY LOC on
the display) and the radio remains on reception. The abbreviation bCLO stands
for "busy channel lock out " (locking device for an occupied channel).

Transmission time delay

For the correct changing of low noise barrier, a short time delay after releasing the
transmission button can be useful. The radio equipment offers the opportunity of
a delay of 0.2 seconds or a switching off.
- For turned off radio equipment, hold the FUNC button and simultaneously
switch the radio on.
