TS-940S AVR Unit Capacitor Change                 4-8-86


In those areas of the country that are subject to large poer line voltage
fluctuations, excessive voltage may be applied to capacitor C12 on the AVR
Unit (X43-1500-00).  These voltage fluctuations might exceed the capacitor
breakdown voltage.  Replacing capacitor C12 with a capacitor having a
higher breakdown voltage will help prevent this potential problem.

Procedure:

On the AVR Unit change C12 from a 6800 uF capacitor to a 5600 uF 25V
capacitor (C90-2037-05).

Time required for this modification is 1 hour or less.
