channels. When a signal is detected on one of the channels, scanning
stops and it is possible to listen the communications on that channel.
Press PTT to transmit on this channel. If there is no transmission
or detected signal on that channel within 5 seconds(time to resume
scanning can be programmed by PC software), radio will resume
scanning. When the DW function is enabled, the DW icon appears on
the LCD. To exit the DW function, press the DW key or the PTT key.
The scan Type above is the SQ mode under SCA Selection in

RF POWER (Outer Dual Concentric)
61
Adjustment of the output power is for AM and FM mode only. Reducing
the power is allowed when communicating with a person who has no
RF GAIN. The normal position of this function is set to maximum, fully
clockwise.
BAND SELECTOR
71
Rotate this switch to select A, B, C, D, E, F band of operation
MODE(PA/CW/AM/FM/USB/LSB)

LSB or USB. Your modulation mode has to correspond with the one
of your correspondent. The mode selector changes the mode of
operation of both transmitter and receiver simultaneously.
Frequency Modulation/FM: for nearby communications on a flat
open field.
Amplitude Modulation/AM: Communication on a field with relief and
obstacles in middle distance (the most used).
Upper and Lower Side Band/USB-LSB: Used for long distance
communications (according to the propagation conditions).
This is frequency tuning knob which can be set as different modes
(refer to CLA Specifications in Functions Menu for more details).
PUSH

This switch is used to control intervals of echo sound
RG GAIN ( Inner Dual Concentric)
51
This switch is for adjusting sensitivity during reception. For long
distance communications RF GAIN should be set to maximum. RF
GAIN can be reduced to avoid distortion, when your correspondent is
close by and when he does not have RF POWER. The normal setting
of this function is on maximum (fully clockwise).
CLARIFIER

it is desired that the control be adjusted only to the point where the
receiver background noise or ambient background noise is eliminated.
Turn fully anticlockwise then slowly clockwise until the receiver noise
disappears. Any signal to be received must now be slightly stronger
than the average received noise. Further clockwise rotation will
increase the threshold level which a signal must overcome in order to
be heard. Only strong signals will be heard at a maximum clockwise
setting.
ECHO(Inner Dual Concentric)
