7-4 Adjustments 8525B/8528 Technical Service Manual
Issue 6 Publication No: 15-02036
Used Indication
Channel numbers will normally be accepted on pressing the Enter pad.
However, if a channel with the entered number has previously been
programmed and the over-write link is not installed, the display will show
USEd. The channel number can be either:
1. changed by entry of a new number on the number pads, or
2. accepted and the previously programmed frequencies over-written by a
second operation of the Enter pad.
Full Indication
When all ninety-nine P channels have been programmed, on pressing the
Enter pad to accept another channel, the display will show Full. A further
press of the Enter pad will over-write the nominated channel. Alternatively
some redundant channels can be deleted and then re-used. If the over-write
protection link is installed, this must first be removed before channels can be
deleted.
Too Hi, Too Lo Indications
If an attempt is made to program a channel with either a Tx or Rx frequency
outside the range of the transceiver, an error message will be displayed. The
error can be corrected by simply entering a new number on the number pads.
