Maintenance
GENERAL
The unit contains no electronic components that can be serviced or
replaced by the user. Repairs should not be attempted by the user.
Warning
Disconnect AC/DC power before performing maintenance.
Although dangerous voltage levels are not exposed, discon-
necting power will ensure an electric shock hazard is not
present.
FUSE
If the AC power fuse or the external power input fuse fails, replace it
with one of equal rating. Repeated failure indicates a more serious
problem. If this happens, refer to the section on maintenance.
MAINTENANCE
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 compo-
nent in a bad communications link.
