Amplifier. The checklist is intended as an aid in the localization of trouble
to a specific module. If a module is suspected of being defective, a new one
should be substituted and the test conducted again. If the substitute module
operates correctly, the original module should be considered defective and
returned to Accurate for repair or replacement as directed below. We strongly
recommend that no internal (component-level) testing or repairs be attempted
on the module. Unauthorized testing or repairs may void the module's
warranty. Also, if the module is part of a registered system, unauthorized
repairs will result in noncompliance with Part 68 of the FCC Rules and
Regulations.
TECHNICAL ASSISTANCE

Customer Service as follows (telephone number are given below):
Contact Accurate Electronic Customer Service
9.03 If a module is diagnosed a defective, follow the replacement procedure
in paragraph 9.04 when a critical service outage exists (e.g., when a system
of a critical circuit is down and no spares are available). If the situation is not
critical, follow the repair and return procedure in paragraph 9.05.
Replacement
9.04 To obtain a replacement module, notify Accurate Electronics. Be sure
to provide all relevant information, including the 104003C part number that
indicates the issue of the module in question. Upon notification, we shall
ship a replacement module to you. If the module in question is in warranty,
the replacement will be shipped at no charge. Pack the defective module in
the replacement module's carton, sign the packing slip included with the
replacement, and enclose it with the defective module (this is your return
authorization). Affix the preaddressed label provided with the replacement
module to the carton being returned, and ship the module prepaid to Accurate
