In order to have an audible distinction between receptions on the active
and the standby frequency, it is possible to receive the receptions from
the standby frequency with a lower volume. Please refer to chapter 2.4.5
for information onto this feature “dual watch volume reduction”.
Quick approach:
•
Select or enter a standby frequency which shall be additionally
monitored.
•
Set SQL with the
SET
key and the
rotary knob to a value
of at least 02.
•
Activate dual watch with
DW
(DW is shown)
•
As soon as no reception is determined on the active frequency, the
mutual monitoring between active and standby frequency starts.
•
In order to deactivate dual watch: press
DW
once more or change
the frequency.
SQL has to be set to 02 at least, as without proper squelch
functionality the radio would not be able to detect whether on
the active frequency a reception takes place.
Don’t forget to interchange the active and standby
frequencies, before answering a call on the standby
frequency.
Using dual-watch requires switching between the active and
the standby frequency. Therefore it may happen that calls
on the active frequency cannot be monitored completely. As
the result we recommend not to use dual-watch in airspaces
where listening watch is required.
