2. [ SQUELCH ] :
Rotate the squelch control ( 1 ) SQUELCH slowly clockwise until the background
noise just disappears while any incoming signal will be heard. The squelch con-
trol should only be turned up enough to stop the background noise on an unused
channel. Turning the control further clockwise will increasingly suppress interfer-
ing signals as well as weak stations. The setting should be made on an unused
channel.
3. CHANNEL SELECTION [ CHANNEL ] :
Select the desired channel 1 - 40 with the channel selector switch ( 4 )
CHANNEL. The display ( 3 ) shows the actual channel. The CH9 function CH9
must not be activated which is indicated by a flashing "9" in the display. In paral-
lel the channels can be controlled by the built in UP/DOWN buttons of the micro-
phone. The channel numbers step in a ring like system UP from 40 to 1 and
DOWN from 1 to 40 and opposite. It is also possible to show the actual fre-
quency ( in MHz ) in the display instead of the channel numbers by pressing the
button ( 15 ) FRQ. This has no influence on the following described functions. By
pressing the button ( 15 ) FRQ a second time the channel number will appear in
the display again.
Radio operation is only possible with the counter station at coinciding channel
numbers or channel frequencies. By pressing the instant channel key ( 16 ) CH9
channel 9 can be selected for transmit and receive immediately. A flashing " 9 "
will appear in the display. No channel selection is possible now. Pressing CH9
again will cancel this function and the unit returns to the previous selected chan-
nel.
4. LAST CHANNEL RECALL [ LCR ] :
By activating button ( 13 ) LCR the transceiver will tune to that channel where
the last transmission was made. Now the actual channel is stored as the last
channel. Pressing the key ( 13 ) LCR again will make the unit return to the actual
channel.
5. OCCUPIED CHANNEL SEARCH ( SCAN ) [ SC ] :
Before selecting the SCAN function set the squelch control ( 1 ) SQUELCH ac-
cording to Para "2" because this function does not work with unmuted receiver.
Depress the key ( 12 ) SC now. In the display appears [ SC ] and the channels
are stepping upwards. SCAN stops on the first occupied channel, where a signal
can trigger the squelch threshold. It continues after 10 seconds when the signal
falls below the squelch threshold. Depressing the key ( 12 ) SC again or any
other, except ( 15 ) FRQ, will stop the SCAN function.
