Basic Operation

7.1

Power on

The On/Off switch is combined with the volume control. To switch on, turn that
control slightly clockwise until it has clicked. To switch off, turn the volume control full
counter clockwise until it has clicked again.
7.2

Volume

Set the volume to your convenience by the VOL control. If the receiver is muted, set
this control to medium and adjust the volume when you receive a signal.
7.3

Squelch

Set the squelch, so that the noise is just not audible. In this position the squelch
opens even for weak signals and is in the most sensitive position. When opening the
squelch beyond this point to the right (clockwise), the signals must be stronger to
come through.
To check for very weak stations the receiver muting can be temporarily disabled by
pressing the MON key. This function is independent from the squelch control and
activated ASQ function.
7.4

ASQ

This automatic squelch function does not need any adjustment and works fully
automatic at maximum sensitivity. It opens at any signal which is good enough to be
understood. Turn the ASQ/PA selector into position 'ASQ'. However, the ASQ
function is limited to normal receiving conditions on the CB band. In case of nuisance
by overreaching far distant stations or if you like to suppress weaker stations, it may
be better to use the standard squelch instead of the ASQ. To disable this function
turn the ASQ/PA selector into position 'Normal'.
7.5

Channel selection

Rotate this knob to select the operating channel. Alternatively the channel can be
selected by the up and down keys on the microphone.
7.6

Select Operation Mode

Press the MODE key to cycle around AM, FM, USB and LSB modes. The selected
mode is shown on the display. They mean:
AM Amplitude modulation A3 with full carrier
FM Narrowband frequency modulation (max. 2.0 kHz range)
USB Single side band modulation, upper side band (Upper Side Band)
