51DT25H
REASON
To reduce patterning on the later version of the above model, the processor (IC1001)
and several other components were changed.
and several other components were changed.
ACTION
As the two processors are not directly interchangeable, it is important that the circuit is
identified before replacing IC1001. If the incorrect IC is fitted, then the receiver will not
operate.
identified before replacing IC1001. If the incorrect IC is fitted, then the receiver will not
operate.
If an 18MHz crystal is fitted in position X1001, use the Service Manual parts list to
identify the circuit components – IC1001 part number is RH-IX1655BMN0 or RH-
IX1655BMN1 (both parts are fully interchangeable).

If a 6MHz crystal is fitted in position IC1001, use the parts listings and diagrams given
below for differences to the Service Manual – IC1001 part number is RH-
