wPush [DW•TRI] momentarily to start dualwatch; push [DW•TRI] for 1 sec. to start tri-watch.

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

-Beep tones sound 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 [DW•TRI] again.
