For the convenience of service technicians and engi­
neers when writing up certain business papers such as
W arranty Reports, Product Information Reports, or report­
ing product failures in any way, the location of the various
unit numbers have been indicated. These unit numbers and
their prefix or suffix are necessary on these papers for
various reasons - such as accounting, follow-up on produc­
tion, etc.
The prefixes on certain units identify the plant in which
the unit was manufactured and thereby permits proper
follow-up of the plant involved to get corrections made when
necessary.
Always include the prefix in the number.
