OTHER FUNCTIONS

■ Dualwatch operation

The Dualwatch operation alternately monitors the active
frequency and standby frequency at certain intervals, while
no signal is detected on either frequency.
If a signal is detected on the active frequency, the
transceiver changes to the active frequency and ignores
the standby frequency until the signal disappears. On the
other hand, if the valid signal is detected on the standby
frequency, the transceiver changes to the standby frequency
and ignores the active frequency.
q Push [DUAL] to enter Dualwatch operation.
• "DUAL" is displayed above the active frequency.
• When a signal is received, "RX" is displayed on the active
or standby frequency. The transceiver ignores the other
frequency.
w Push [DUAL] again to exit Dualwatch operation.
• "DUAL" disappears.

■ Priority watch

If a signal is detected on the standby frequency while
Dualwatch operation with the Priority watch is enabled
(p. 21), the transceiver changes to the standby frequency
and monitors the active frequency at the same time.
q Push [DUAL] to enter Dualwatch operation.
• "DUAL" is displayed above the active frequency.
• When receiving a signal on the standby frequency, the standby
frequency ' s "RX" blinks. However, the transceiver continues to
monitor the active frequency.
