Equipment
The list of equipment contained in Table 2 includes all of the standard test
equipment required for servicing two-way portable radios, as well as several
unique items designed specifically for servicing this family of radios. The
“Characteristics” column is included so that equivalent equipment may be
substituted; however, when no information is provided in this column, the
specific Motorola model listed is either a unique item or no substitution is
recommended.
Service Aids Refer to Table 3, “Service Aids,” for a listing and description of the service aids
designed specifically for servicing this family of radios. These kits and/or parts
are available from the Motorola Parts Division offices listed in the
“Replacement Parts Ordering” section located on the inside back cover of this
manual. While all of these items are available from Motorola, most are
standard shop equipment items, and any equivalent item capable of the same
performance may be substituted for the item listed.
