SCAN
Short press to enter ALL SCAN mode.
ALL SCAN sequentially scans all channels for activity.
When a signal is received, scanning stops at that channel and the BUSY icon
appears on the screen. If the signal ceases for more than 5 seconds, the
scan automatically resumes.
Turn the channel knob to temporarily skip over (lock out) a busy channel
and resume the scan. The direction turned determines if the scan goes
up or down the channel numbers (ie 'forward' or 'reverse'). If it is still busy
when the scan completes a full cycle, it will stop again at this channel. Note
that it is not possible to skip over the priority channel.
Press ENT to permanently skip over the channel. The SKIP icon will show on
the LCD for this channel.
To cancel a skipped channel, select the channel while in normal mode
(non-scan mode) then press the ENT key - the SKIP icon will disappear.
Repowering the radio also restores all skipped channels.
Press SCAN or EXIT while scanning is active to stop at the current channel
and return to normal operation.
Long press SCAN from normal operation to enter the SCAN menu.

Long press to set the current channel as the watch channel.
When a short press is made on the TRI key, the radio will either switch to
DUAL or TRI watch mode depending on whether a watch channel has
been setup.
Without a watch channel the radio will go to DUAL WATCH, where the
channels 'watched' are the current channel and the priority channel (the
distress channel, CH16 for most countries).
With a watch channel selected, TRI WATCH is enabled, where the channels
'watched' are the current channel the 'watch' channel, and the priority
channel (the distress channel, CH16 for most countries).
If the radio is set to 'Country: USA', two priority channels are watched -
Channel 9 and Channel 16.
