Warning
Disconnect power before performing maintenance.
Although dangerous voltage levels are not exposed, discon-
necting power will ensure an electric shock hazard is not
present.
GENERAL
The modem contains no internal electronic components that can be
serviced or replaced by the user. Repairs should not be attempted by the
user.
FUSE
If a fuse fails, replace it with one of equal rating. Repeated failure indi-
cates a more serious problem.
MAINTENANCE
The modem provides maintenance free service. Periodically it is neces-
sary 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 compo-
nent in a bad communications link.
If the unit appears faulty, contact the Motorola Field Service Depart-
ment at 1-800-221-4380 for service and assistance. Do not return the
unit without prior instructions.
