DUALWATCH/TRI-WATCH SIMULATION

Call channel

DualwatchTri-watch

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].

If no signal is received, the transceiver enters the power saving condition for 0.5 sec. after checking the operating channel every cycle.

Operation

qSelect the desired operating channel.

wPush [SCN•DUAL] to start dualwatch or tri-watch (depend- ing on SET mode setting).

“DUAL” blinks during dualwatch; “TRI” blinks during tri-watch.

A beep tone sounds when a signal is received on Channel 16.

Tri-watch becomes dualwatch when receiving a signal on the call

channel.

eTo cancel dualwatch/tri-watch, push [SCN•DUAL] again.

[Example]: Operating tri-watch on INT channel 07.

Push for 1 sec.
