AMENDMENT INSTRUCTION NO. 237
AL1 TO TM1200 ISSUE 1
RPR 561/RPR 561K PAGING TRANSCEIVER
APRIL 1999
The attached amendment should be incorporated in the above Technical Manual
as soon as possible.
In line with the company policy of continued technical advancement, changes to
circuit diagrams and component layout diagrams are continually taking place. It is
not company policy that the technical manual should cover all previous issues of
products but only the latest design state. To this end, where an amendment
changes either the circuit diagram or component layout diagram, it may be prudent
to archive the previous diagrams, particularly if your product is of old design.
