5) SWR/CAL:
Used for the calibration of the SWR meter (see «Adjustment of SWR» page 27,
§ 5).
6) TONE:
This function is used to adjust the tone during reception. Turn on to activate
the function.
7) BAND SELECTOR:
Unused key on this version.
8) RF POWER:
When you turn this knob fully clockwise the RF power (norm peak 4 watts) is at
maximum. You should reduce transmission power when the communication
is close to someone who does not have RF GAIN.
The normal setting of this knob is on maximum (fully clockwise).
9) ASC (Automatic Squelch Control) and ROGER BEEP:
a) ASC (Automatic Squelch Control)
Both functions ASC and ROGER BEEP will be activated pulling (9) switch see
page 27, point 2).
b) ROGER BEEP
When you finish speaking and you release the «push-to-talk» switch to allow
your correspondent to speak, a «beep» sounds. Radio CB is what is known as
a «simplex» method of communication, that is to say, that you cannot listen
and speak at the same time (as you can, for example, with the telephone).
It was custom to say «roger» to indicate to your correspondent that you’d
finished speaking and that it was his turn to talk. The word «roger» has now
been replaced with a beep, hence its name, «Roger Beep».
10) CHANNEL SELECTOR ROTARY KNOB:
Turning this knob allows you to choose a channel (1-40) for transmitting and
receiving.
11) RX/TX:
RX indicator (green) lights when the receiver is in operation and TX indicator
(red) lights when the transmitter is in operation.
12) HI/LOW:
Unused key on this version.
13) DISPLAY:
The display shows the current channel. The bargraph shows the level of
reception, the emitted level of power and the measured standing wave ratio.
14) MODE:
Use this key to select AM or FM. The modulation mode must correspond with
that of the person with whom you communicate.
A/ Amplitude Modulation (AM) is for communications in areas where there
are obstacles and over medium distances.
B/ Frequency Modulation (FM) is for nearby communications in flat, open
areas. It gives better quality of communication (squelch adjustment needs
more finesse).
