SERVICE BULLETINS
The only service bulletin I have found for the R-5000 is number SB-919 dated 7-21-87.
It involves the capability to change the frequency from the remote interface. This only seems to
be a issue with receivers of serial number 8049999 or less. The problem can be corrected by
making sure the Integrated circuit in IC52 is an MBM27C128-25JA2.
