Triple Watch Function
Pressing and holding the monitor button activates the Triple watch
function. The Triple Watch feature allows for monitoring of 2 or 3
channels, including the currently selected channel and the channels
stored in TRI 1 and TRI 2.
In order to store these channels, they are set on the radio in the same
way you would set normal channels with any additional features set
(CTCSS/DCS/Duplex). This channel is then selected in TRI 1 or TRI 2 via
the menu function. If only one additional channel is required then select
“off” in TRI 2.
Once Watch is activated, by pressing and holding the Monitor button,
the TRI 1 and TRI 2 channels are checked in the following sequence:
Main channel is checked for 0.7 of a second, then TRI 1 for 0.15
seconds, TRI 2 for 0.15 seconds and then back to the Main channel.
The sequence is repeated until turned off, or until a signal is detected.
If there is a signal present on TRI 1 or TRI 2, the radio will wait on that
channel. For 5 seconds after the signal is no longer present, the user
can push and hold the monitor button to activate that as the normal
channel, otherwise the Watch will continue in its normal sequence.
Watch can be disabled by pushing and holding the monitor button.
