The bargraph shows the level of reception and the level of power emitted.
7) CH 19/9:
Channels 9 AM and 19 AM are automatically selected when you depress this
key.
Activate Channel 19 AM by depressing the key once. "EMG" appears in the
display. A second depression of this key activates Channel 9 AM and "EMG"
remains in the display. To return to the previous configuration re-depress the
same key and "EMG" disappears from the display.
8) SCAN:
This function allows you to "scan" all the channels. Scanning stops when a
signal is detected. By depressing the Scan key when a signal is detected
scanning starts again from the next channel Five seconds after the end of the
signal, scanning continues. By going into transmission mode you may
communicate with your correspondent and your CB leaves the scanning
mode.
This function is activated by depressing the SCAN key and "SCAN" appears
in the display. Scanning starts after you have adjusted the squelch level. To
cancel, depress the same key, "SCAN" disappears from the display and the
set returns to the previous configuration.
9) 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).
10)DW (Dual Watch):
This function lets you watch over Channels 9 AM and 19 AM and the channel
you are using. The set goes to and from the two channels (approximately 0,5
second per channel) and stops on the one where a signal is detected
(reception level defined by squelch). Dual Watch restarts five seconds after
the end of the signal, unless you go into transmission.
Press the DW key to watch over Channel 19 AM and the channel you are using.
"DW" appears in the display. Press the key a second time to activate a watch
over Channel 9 and the channel you are using. "DW" remains in the display.
To cancel, press the same key. "DW" disappears from the display.
11)MIC GAIN:
Is for regulating microphone sensitivity, when using a microphone other than
the one supplied with your PRESIDENT HERBERT ASC. (pre-amplified).
The normal setting of this knob is fully clockwise.
12)HI-CUT:
Cuts out high frequency interference. Its use depends on reception conditions.
Depress the key to use this function, "HC" appears in the display. To cancel,
press the same key, "HC" disappears from the display.
13)SWR:
This function allows you, when in transmission, to take an SWR reading. This is
carried out when a change is made to the antenna or its connections. If the
SWR reading is above 1.8 it is necessary to re-adjust the SWR.
Go into transmission mode, and depress SWR. "SWR "appears in the display.
The SWR value can be seen on the lower scale of the bargraph. To cancel this
function, press SWR again and "SWR" disappears from the display.
14)PA (Public Address):
An external loud speaker can be connected to your PRESIDENT HERBERT ASC
by the jack plug situated on the back panel PA.SP ( E ). By pressing the PA key,
the message transmitted into the microphone will be directed towards the
external speaker and be amplified. Hold the microphone far enough away
from this loud speaker so as to avoid the Larsen effect (accoustic feedback).
