SECTION 6 - MAINTENANCE

INTRODUCTION

The frequency control slave requires minimal maintenance.
The following maintenance schedule will ensure troublefree
service.

NOTE: Only qualified personnel should perform maintenance.

MAINTENANCE

The FCS maintenance schedule is shown in Table 

6-1

. Perform

these tasks at the specified intervals. 

REPAIR/REPLACEMENT PROCEDURES

The frequency control slave is designed for long, troublefree
service. There are no parts on the FCS that the user can ser-
vice. If a failure occurs, refer to 

Section 5

 for information to

restore operation.
