6.Press e and select OFS for entering the offset channel. Then use the keypad to enter a new offset channel, then press E. Then press HOLD/RESUME. The scanner returns to the previous screen.

Notes

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

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.

toggling the status bit

On Type II trunking systems, there is a method by which specialized types of communications use unique talk group numbers. An emergency call will occur on a unique talk group from its primary assignment, for example. Because the scanner defaults to status-bit on mode, you never need to worry about missing these transmissions. If you have programmed talk group 33264 into scan list memory, for example, and there is an emergency call within that 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 I trunking system.

1.Select the trunking programming mode and the bank you want to change.

2.Press e or d to select E1, E2-800, E2-Hi or E2-UHF, then press E.

3.Press e or d to select S-bit, then press E.

4.Press e or d to select Sbt ON or Sbt OFF, then press E. The scanner returns to status bit list item.
