BULLETIN # 1040
MODEL: TM-642A/TM-742A/TM-942A
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:
Qty Description Old Kenwood Part No. New Kenwood Part No.
1 Microprocessor HD6433388A22F HD6433388A25F
Procedure: When ordering a replacement microprocessor you will be supplied
with the new version. Please make sure you understand the limitations of
this new microprocessor with respect to NO 800 Mhz receive.
