7. Enter a new offset channel with the keypad.

Note: You can only input within a range of 380-759.

8.Press E.

The display changes for entering the next base frequency.

9.To exit from this mode, press MENU repeatedly.

Note: • If the system is not tracking properly, you may need 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.

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 the second (of a maximum of three) base/space/offset combinations. Since almost all systems only use one set, press MENU to exit the programming mode and return

to scanning.

Toggling the Status Bit

On Type II trunking systems there is a method by which specialised types of communications utilise unique talkgroup numbers. An emergency call will occur on a unique talkgroup from its primary assignment, for example. Because the UBC780XLT 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.
