As long as a radio call is received, the REPLAY function is deactivated.
This also means that the squelch setting must not be zero.
2.9 DUAL WATCH Operation
The ATR833-II comprises one receiver; therefore “dual watch”
(simultaneously monitoring two frequencies) is implemented by
alternating automatically between the active and the standby frequency.
With dual watch mode active, basically the standby frequency is tuned in,
shortly interrupted in regular intervals by tuning in the active frequency
for a fraction of a second.
Every then detected radio signal on the active frequency has priority, and
pauses the dual watch monitoring of the standby frequency, as long as
the reception/transmission continues on the active frequency.
Transmissions are always done one the active frequency.
The dual watch mode is activated by pressing DW, and indicated by a
changing the “SBY” label for the standby frequency to “DW”.
