INSTALLATION
2-1. UNPACKING.
Carefully remove the unit from the shipping carton
and examine it for evidence of damage. If any
damage is discovered, immediately notify the trans-
portation company that delivered the unit. Be sure
to keep the shipping carton and packing material as
the transportation company will want to examine
them if there is a damage claim. Keep the carton
and packing material even if no shipping damage
occurs. Having the original carton available makes
packing the unit much easier if it should ever be
necessary to store it or return it to the factory for
service.
NOTE
Fill out the enclosed registration card
and return it to the factory. immediately
to insure registration and validation of
the warranty.

The location of the TR—4C is not critical. However,
care should be taken to insure that adequate clear-

controls and connectors. Do not cover the top of
the cabinet with books, papers or other equipment
as overheating may result.
