ENERAL

NFORMATION Optional equipment enhances the Electra Elite 192 system. This

equipment can be purchased separately from the system and added as

the customer business grows. Except as noted, these adapters can be

installed on Electra Elite Multiline Terminals. With the exception of the

VDD-U Unit, the adapters can also be used with D

term

Series E Multiline

Ter minals .

A Multiline Terminal can have up to three adapters installed at the same

time. When attaching an APR-U, CTA-U, CTU(C)-U, CTU(S)-U, HFU-U,

or VDD-U Unit, an external power supply is required. Only one power

supply is needed even when more than one adapter is installed. When an

adapter is installed for the first time into a telephone, the base cover on the

Multiline Terminal may have to be modified. The base cover has two

access panels that are removed before the cover can be closed over the

adapters to complete the installation.
