WORKING CHANNEL MEMORIES
The GX750 has two dedicated priority channel memories that allow you to store and recall two
often-used channels. These memories are accessed using keys labelled
PR1
and
PR2
.
PR1
is
also used as the priority channel for the Triple Watch function (see feature description later in
this manual).
Storing Priority Memories (PR1/PR2)
To store a channel in the PR1 or PR2 memory, select the required channel using the channel
control, then press and hold the
PR1
or
PR2
key. The channel number will flash then a high
beep will be heard as the channel is stored.
Recalling Priority Memories (PR1/PR2)
Briefly press the
PR1
or
PR2
key. The radio will switch immediately to the channel stored in that
memory and ‘PR1’ or ‘PR2’ is displayed. If the radio was scanning the scan will be cancelled.
DUAL WATCH KEY (DW)
The Dual Watch function is a two-channel scan feature where the GX750 switches between
channel 16 and any other selected channel. This feature allows you to monitor a working or club
channel while still being able to receive important broadcasts on channel 16.
