wise and adjust it to a comfortable listening level. If the transceiver is on a clear
channel and not muted by the squelch function a noise should be heard from the
speaker now. The back illumination of the display
( 3 )
and the front panel will
light up. When the unit is switched on the first time or after being disconnected
for a longer period the first channel will be channel
9
in
FM
mode. The display
will show
[ 9, FM and SRF ]
. If the power source is not disconnected after
switching off, the settings and functions will be stored ( memory backup ). All cor-
rect entries will be confirmed by a receipt tone.
2. Squelch function [ SQUELCH ] :
Rotate the squelch control
( 1 ) [ SQUELCH ]
slowly clockwise until the back-
ground noise just disappears while any incoming signal will be heard. The
squelch control should only be turned up enough to stop the background noise
on an unused channel. Turning the control further clockwise will increasingly
suppress interfering 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
must not be activated which will be indicated by a flashing
9
in the display. In
parallel the channels can be controlled by the built-in
UP/DOWN
buttons of the
microphone. The channel numbers step in a ring like system UP from 40 to 1
and DOWN from 1 to 40.
It is also possible to show the actual frequency ( in MHz ) in the display instead
of the channel numbers by pressing the button
( 15 ) [ FRQ ]
. This has no influ-
ence 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 and modulations. 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
( 16 )
[ CH9 ]
again will cancel this function and the unit returns to the previous se-
lected channel.
4. Modulation selection [ A/F ] :
By pushing the key
( 13 ) [ A/F ]
the transceiver will toggle between AM and FM
mode. The actual modulation type is indicated by the symbols
[ FM, AM ]
in the
display
( 3 )
.
With the
TEAM SelCom 4040
all 40 channels can be selected both in AM and
in FM mode. In FM mode the transmit output power is 4 W and in AM mode it is
1 W.
