to try a new Base Frequency or Offset Channel or
you may be missing frequencies from the system.

• You can set up to three Base, Spacing and Offsets
for Motorola VHF/UHF trunked systems.
13. The Offset Channel for the first set should be CH380 (just
press MENU/BACK to confirm this as the default).
14. After you have pressed MENU/BACK to confirm CH380,
the display will change to allow you to set the second (of a
maximum of three) Base/Space/Offset combinations.
Since almost all systems only use one set, press

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
BC250D 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.
