BULLETIN # 993
MODEL: TH-27A
SUBJECT: LOW TRANSMIT POWER

We have noticed some variation in the output power provided by Toshiba 
S-AV22A power modules with a production code of "1I". Modules with this 
production code might exhibit low or no transmitter output power. This 
procedure will correct this problem .


Parts Required:

0.01 uF axial lead capacitor---------------------- C91-0769-05


Procedure: 

1. Remove chip capacitors C17 and C18 from the TX-RX Unit (X57-3640-11.) 

2. Install the new axial lead capacitor as shown in the accompanying diagram. 
   The new C18 is connected from the board edge on one side and to the pad 
   the "old" C18 on the other side. The cap should lay along the board edge. 

Note: Deleting C17 and C18 alone will not correct this symptom. The new C18 
will be used to stabilize circuit performance. Deleting C17 alone will not 
cure the symptom.

Time required for this modification is 30 minutes or less.
