To terminate the triple watch, touch the [TW STOP]
button.
The channels for triple watch are stopped and the
transceiver starts receiving. (The example at right
shows when triple watch is stopped on channel 10.)
The triple watch is also terminated when off-hook or
PTT ON is detected or a channel is set in the DSC
transmission menu.
- During the triple watch, the radiotelephone watches channel 16 and two other
channels and the channels cycle in order with a dwell time of 0.14/0.43/0.43
seconds.
- If the squelch is opened on channel 16, the triple watch pauses and the watch
continues on channel 16. If squelch is closed again, the dual watch resumes 2
seconds later.
- If a signal is detected and the squelch is opened on one of the other two channels
in the triple watch, the dwell time changes to a cycle of 0.14/1.86 seconds and the
watch continues (other channels are not scanned and watched). If squelch then
remains continuously closed (until the end of the triple watch cycle time), the
triple watch resumes as normal. Furthermore, if in this state a signal is detected
on channel 16, then channel 16 is watched continuously as described above.
