Issue and Resolution 
Issue 
A small number of reverse transmitters used in the GS7000, GainMaker, and 694X 
Nodes with specific date codes (identified above) may contain a defective capacitor.   
In units where this component fails, transmitters may stop sending an upstream RF 
signal, although the light is still present. 
Resolution 
If you have a transmitter that displays this symptom and contains a capacitor with a 
date code of 916, 917, or 919 (As shown in illustration #4), the transmitter(s) should 
be returned to our repair facility for replacement. 
It has been our experience that all failures caused by this capacitor have occurred 
within a few hours of installation and power-up.  Transmitters that have not failed 
within hours (up to a week after installation) are not failing beyond that time frame.  
Not all capacitors in the noted transmitter date code range are defective. 
If you have uninstalled (warehoused) transmitters (within the affected part number 
list and date codes) or nodes containing these potentially affected transmitters in 
your warehouse, use this bulletin as a guide for how to inspect these units for 
defective capacitors.   DO NOT ATTEMPT TO OPEN THE TRANSMITTER.   
If the inspection yields a defective capacitor, the unit should be returned for service.
