* Motorola Depot Servicing only
Reference designators with an asterisk indicate
components that are not field-replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.
†
Replacement boards must be ordered from
RPSO (formerly CCSD and/or AAD) using the
number shown in the model charts in Chapters 4
- 13. Boards are not orderable using the 84-
prefixed number.
