systems.
10.The offset channel for the first set should be CH380 (just press
E to confirm this as the
default).
11. After you have pressed
E to confirm CH380, the display will change to allow you to set

systems only use one set, press

scanning.
Toggling the Status Bit
On Type II trunking systems there is a method by which specialized types of
communications utilize unique talkgroup numbers. An emergency call will occur on a unique
talkgroup from its primary assignment, for example. Because the BC780XLT defaults to
Status-Bit On mode, you never need to worry about missing these transmissions. If you
have programmed talkgroup 33264 into Scan List memory, for example, and there is an
emergency call within the group, you will hear it on 33264.
The only time you may wish to turn Status Bits off is if you're trying to figure out the proper
fleet map of a Type 1 trunking system. To turn Status Bits off, enter into the menu mode and
select
TRUNK DATA - BANK NO. - STATUS BIT. (This feature does not apply to EDACS
and LTR operation within the scanner.) Then use
HOLD/▲ or LIMIT/▼ to change the setting
(on to off) and press
E to program your change.
