OPERATION
■
On/Off
To switch on/off the radio turn the volume switch [VOL]
clockwise / counterclockwise over the threshold.
■ Channel selection
Use the channel selector keys and at the microphone
or at the radio for channel selection. The actual channel
number is displayed on the LCD.
■
Transmitting
For signal transmission, press and hold the PTT key at
the microphone. The TX symbol appears in the LCD.
For best quality, speak normally at a distance of 5–10
cm (2 - 4 inches). Speaking too loud will cause distor-
tion and makes the signal difficult to understand. While
the set is in the transmit mode there is no key entry
possible and the receiver is muted. On completion of
the transmission release the PTT key and the radio will
switch back to receiving mode.
■
Squelch
The radio is equipped with an automatic (ASQ) and a
manual squelch (SQ). Both can be adjusted. The strong
background noise, which occurs always on free chan-
nels, can be suppressed by the squelch function, which
has an automatic and a manual mode.
By turning the squelch control
[SQ/ASQ] slowly clock-
wise you will find a position where the noise disappe-
ars. The squelch control should only be turned up far
enough to mute background noise on a signal-free
channel. Turning the control further clockwise will in-
creasingly suppress stronger interfering signals as well
as weak stations.
The automatic squelch
[ASQ] uses a preset average
value. It can be activated by turning the squelch control
counterclockwise all the way to the end. The automatic
squelch mode is indicated by the ASQ symbol
(ASQ)
in the LCD.
