Environmental Requirements
The switch and the DEFINITY AUDIX system generate heat as they
operate. If the operating environment for the system and the switch is
not properly ventilated, this heat can cause these systems to
malfunction. Their operations can also be affected by other
environmental conditions, such as humidity and air quality.
Switch documentation identifies specific guidelines for the switch’s
operating temperature and environment. Generally, the customer should
use these guidelines for creating a suitable operating environment for
the DEFINITY AUDIX system and protecting the system from harmful
environmental conditions. The following guidelines represent the
recommended environmental conditions for DEFINITY switch Release
7.1 and DEFINITY AUDIX system Release 4.0. See the system
description for the customer’s switch for more information about
