AUDIO TOWER REPLACEMENT

NOTE

If installing a completely new C3 Maestro

console system (new PC and new Enhanced

Audio Enclosure equipment), disregard this

section entirely and proceed to the “POWER-

UP PROCEDURE” on page 36.

This section lists the steps necessary to replace earlier

Audio Tower hardware with Enhanced Audio Enclosure

hardware. Instructions are not included on replacing

Personal Computer (PC) hardware and/or software as it is

assumed these items are already Windows NT-ready. To

avoid duplication of information, many references are made

to other Enhanced Audio Enclosure-related installation and

set-up sections within this manual.

1. Power-Down and Cable Disconnections

REMOVE AC POWER from the PC system.

REMOVE AC POWER from the Audio Tower

system.

Disconnect the Dispatch Keyboard from the Logic

Board installed in the PC. If a new keyboard (with

DB-9 connector) is supplied, this old keyboard is no

longer needed.
