REPLACEABLE PARTS
5-4 . EXCHANGE ASSEMBLIES
Some parts used in this instrument have been
set up for an exchange program. This
program allows the customer to exchange his
faulty assembly with one that has been
repaired, calibrated, and performance-verified
by the factory . The cost is significantly less
than that of a new part . The exchange parts
have a part number in the form XXXXX-695XX .
After receiving the repaired exchange part
from Hewlett-Packard, a United States cus-
tomer has 30 days to return the faulty assemb-
ly . For orders not originating in the United
States, .contact the local Hewlett-Packard ser-
vice organization . If the faulty assembly is not
returned within the warranty time limit, the
customer will be charged an additional
amount . The additional amount will be the dif-
ference in price between a new assembly and
that of an exchange assembly .
