* Motorola Depot Servicing only
Reference designators with an asterisk indicate compo-
nents which are not fieldreplaceable 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.
