priority code in order to insure proper audio routing. Expansion
Modules are designed to connect together in a bus fashion. The IMR-
2 is a priority [C3] device meaning that it would connect after any [A] or
[B] series devices, after a [C1] or [C2], but before a [C4], [D] or any
subsequent designation. The order of the devices is important to
insure proper functioning of all devices. If the IMR-2 is your only
expansion device then it can connect directly to the Audio Center.
4) Connect the IMR-2 to the 26-pin ribbon cable in the proper location
making sure that the ears on the locking 26-pin connector are latched,
and the blue protective tape is removed from any connectors that need
to be used.
5) Re-connect power to the system.
