… back to Volume
The return to the default display (VOL) is carried out by a long press of
SET or happens automatically after 10 seconds of inactivity.
The chosen setting can be adjusted by the
VOL/SEL
rotary knob.
2.5.1 VOL
– Volume
The radio returns automatically to the volume setting, when a value has
been set with the VOL/SEL turn knob.
Turning the
VOL/SEL
knob adjusts the volume of received radio signals.
The higher the value, the louder the reception of radio signals.
Range 1
– 20
2.5.2 SQL
– Squelch (noise barrier)
In the Squelch Menu SQL the squelch level can be adjusted with the
help of the
VOL/SEL
rotary knob. (Note: This is not related in any way to
the intercom functionality.)
This is a threshold that has to be exceeded by radio signal levels from
other transmitters in order to activate the reception circuitry. The higher
the number, the stronger the radio signals have to be in order to be
received.
The VOL setting controls the volume of received radio
signals only, not the volume of the intercom or the external
audio input
– these are set separately with INT and EXT.
