FUSE
MAINTENANCE
Warning: Disconnect power before performing maintenance.
Although dangerous voltage levels are not exposed,
disconnecting power will ensure no electric shock hazard is
present.
The unit contains no internal electronic components that can
be serviced or replaced by the user. Repairs should not be
attempted by the user.
If a fuse fails, replace it with one of equal rating. Repeated
failure indicates a more serious problem.
The unit provides maintenance free service. Periodically it is
necessary to remove dust that has collected on internal
components. Remove dust with a soft bristle brush and low
pressure air or vacuum. Before attempting diagnostic tests,
check that all connectors and plugs are firmly inserted. The test
procedures will identify the faulty component in a bad
communications link.
If the unit appears faulty, contact your Motorola
representative. Do not return the unit without prior
instructions.
