Parts Replacement and Substitution

When damaged parts are replaced, identical parts should be used. If the identical replacement part
is not locally available, check the parts list for the proper Motorola part number and order the part
from the nearest Motorola Radio Products and Solution Organization listed in the "SUPPORT
CENTRES" section of this manual.
