If a signal is received on Channel 16, Dualwatch/Tri-watch pauses on Channel 16 until the signal disappears.

If a signal is received on the call channel during Tri-watch, Tri-watch becomes Dualwatch until the signal disappears.

To transmit on the selected channel during Dualwatch/Tri- watch, push and hold [PTT].

Operation

qSelect Dualwatch or Tri-watch in Set mode. (p. 56) w Rotate [DIAL] to select the desired operating channel.

e Push [CH/WX•DUAL•U/I/C] for 1 sec. to start Dualwatch or Tri-watch.

DUAL 16” appears during Dualwatch; “TRI 16” appears dur- ing Tri-watch.

A beep tone sounds when a signal is received on Channel 16. r To cancel Dualwatch/Tri-watch, push [CH/WX•DUAL•U/I/C]

again.
