INTRODUCTION
The WJ PCS Repeaters are designed to operate for extended periods of time with minimum routine
maintenance. Inspection and performance tests should be conducted at regular intervals consistent
with the facility's normal scheduling and after troubleshooting. No routine adjustments are required.
Troubleshooting and performance tests can be most effectively carried out if the technician first
familiarizes himself with the operating instructions and circuit descriptions.

PREVENTIVE MAINTENANCE PROCEDURES
The R19XX repeaters are designed to operate for extended periods of time with minimum
maintenance. Normally, the only preventive maintenance tasks to consider are:
a.
Cleaning the unit.
b.
Inspecting the outside of the unit for physically worn, damaged, loose, or overheated
parts.
c.
Performing a performance check of the unit.
If the equipment is used in an environment where a great deal of dust, high temperature, or high
humidity is present, the frequency of the checks should be increased.
