DUAL WATCH KEY (DW)
The Dual Watch function is a 2 Channel scan feature where
the GX600A switches between Channel 16 and any other
selected channel. This allows you to monitor a working
or club channel while still being able to receive important
broadcasts on Channel 16.
To use the Dual Watch function, select your preferred
working channel – either by using the or keys – or by
selecting one of the stored CHAN A or CHAN B memories
- then briefly press the DW key. A high beep with be
heard and ‘DW’ will appear on the display. The GX600A
will now monitor the selected channel AND Channel 16
by alternating equally between them. Only the working
channel number is shown on the display when
Dual Watching.
To cancel Dual Watching, briefly press the DW key again.
