7 Audio Programming Mode
Audio programming is normally performed once all other programming has been completed. These
commands allow the installer/programmer to fine tune the IA500’s audio settings to maximize the
performance of the attached phone line services.
Field audio programming can have a negative effect on the performance of the IA500 if the person
implementing these changes is not thoroughly familiar with telecommunication systems.
NOTE: All changes can easily be reversed by using 99 - # at any time during the AUDIO PRO-
GRAMMING MODE session (i.e., 99 - # resets all programming modifications back to factory default
settings).
1. Call the IA500 by dialing its assigned phone number or extension.
