WORKING CHANNEL MEMORIES
The GX600 has two dedicated ‘working channel’ memories
called Channel A and Channel B. These allow you to
store and recall two often-used working channels. These
memories are accessed using keys labeled
CHAN A
and
CHAN B
. Channel A is also used as the priority channel
for the Triple Watch function (see feature description later
in this manual). These channel memories also allow faster
channel switching across the band than would normally be
possible using the or keys. E.g from CH16 to CH67.
Channel A
To store a frequency in Channel A, select the required
channel using the or keys, then press and hold the
CHAN A
key for 1.5 seconds. The channel number will flash
