Reference designators with an asterisk indicate
components which 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 Section 1.
Boards are not orderable using the 84-prefixed
number.
