4.2 Operating Instructions
Turn ON the transceiver with the right toggle switch (lever up "ON").
Select the desired operating frequency by rotating the increment/decrement knobs
either clockwise or counterclockwise. A clockwise rotation will increment the previous
frequency while a counterclockwise rotation will decrement the previous frequency.
The larger inside knob will change the MHz-portion, the smaller outside knob will
change the kHz-portion. At one band-edge (000 or 975 kHz) the following 25 kHz
change will wrap around to the other band-edge.
FSG 71M:
To select the desired operating frequency rotate the channel selector fully clockwise.
To tune the radio to a stored operating frequency rotate the channel selector switch to
the desired channel no. (1 to 10). The receiver is always tuned to the frequency
appearing in the display.
Set the left toggle switch to "Squelch OFF"-position (lever down) to override the
automatic squelch and rotate the "VOL" knob for desired listening level on the noise
being produced by the receiver. Set the left toggle switch to "SQ" (lever up) to activate
the automatic squelch.
A warm-up period is not required. However, at temperatures of -20°C, the LC display
needs approx. 1 sec. until it is fully visible when frequency is changed.
For transmit operation select the desired frequency, depress the push-to-talk button
and speak into the microphone. The microphone must be kept close to the lips in order
to cancel noise like from the engine etc. Enunciate clearly at a constant loudness.
During transmit operation, the yellow LED "TX"-indicator will light on the front panel,
signaling that the push-to-talk button is depressed.
During receive operation rotate the "VOL" knob for desired volume.
IMPORTANT!
•
If radio is battery powered frequent transmitting and loud receiver
volume reduce available operating time.
