Dual Watch - Yaesu VR-500 Operating Manual

Dual Watch

The Dual Watch feature allows you to monitor two frequencies, with the radio rapidly
switching between the two channels, looking for activity. As with scanning operation, the
VR-500 will halt when one of the channels becomes occupied by a signal strong enough to
open the Squelch.
The Dual Watch system includes special memories which can store up to ten pairs of Dual
Watch frequencies. These memories are pre-programmed at the factory, but can quickly be
programmed by you for monitoring of your favorite frequencies on a priority basis.
To activate Dual Watch:
•
Press the [7(DW)] key while pressing the [FUNC] key. The radio will begin Dual
Watch operation.
‚
Once you have initiated Dual Watch operation, press the key corresponding to the
Dual Watch Memory as shown below. Dual Watch will cause
the radio to switch back and forth (rapidly) between the Pre-
Programmable Frequency pair selected (for example, if you
press [8], Dual Watch will switch every 0.2 second be-
tween144.000 MHz and 430.000 MHz.

Dual Watch will halt when the VR-500 receives a signal strong enough to break through
the Squelch threshold. The radio will then hold on that frequency according to the
setting of the "RESUME" mode, described previously.
„
To stop Dual Watch manually, just rotate the DIAL knob one click. If you like, you can
then tune manually back and forth between the two Dual Watch memories by rotating
the DIAL knob.

Press the [CLR(P.SET)] key to cancel Dual Watch operation and return to the previ-
ous operating mode (VFO or Memory).
