for distribution to station receivers and an expan-
sion port connector. The expansion port allows an
optional 16-way to be added to the system.
UNPACKING
Each major component of the TTA system is indi-
vidually packaged and shipped via motor freight or
UPS. It is important to report any visible damage to
the carrier immediately. It is the customer's respon-
sibility to file damage claims with the carrier within
a short period of time after delivery (1 to 5 days).
PRE-INSTALLATION CHECKOUT
The following pre-installation tests should be per-
formed after unpacking the system to verify nothing
has loosened during transit. Additionally, the sys-
tem should be made operational on the bench with
all components at ground level to verify proper
electrical performance.
The tower top box should NOT be
installed on the tower until all of the
pre-installation inspections and tests
have been successfully completed.
Mechanical Inspection
It is advisable to check the tightness of the hold-
down screws for the base unit assemblies to insure
nothing loosened during shipment. Likewise, check
all of the cable connections on the base control unit
