BULLETIN # 1038
MODEL: TH-78A
SUBJECT: Microprocessor Change 

Symptom: Due to a recent rule change by the FCC it is no longer possible 
to supply transceviers, or provide replacement microprocessors that would 
allow a transceiver to receive in the 800 MHz band.

Corrective Action: The microprocessor program of IC5 has been modified to 
prevent 800 MHz band reception. Production has been changed beginning with 
serial number lot 510XXXX. Units produced after this point will not be 
capable of 800 MHz reception.

Parts Required:

Description        Old Kenwood Part No.      New Kenwood Part No.

Microprocessor     75517GF-170-3B9           75517GF-257-3B9

Procedure: When ordering a replacement microprocessor you will be supplied 
with the new version. Please make sure that you understand the limitations 
of this new microprocessor with respect to NO 800 Mhz Capability.
