IA500

Administrator Guide

7.1 Audio Program Effects

Due to variation in telephone line voltage and loop current, changes will affect the quality of sound

from and to the IA500. Code Blue has attempted to provide a conguration to match a majority of

normal installations. However, manual changes may be required to achieve the best performance.

1. Broken Audio

a. Discontinuous audio signal between operator and user is normally related to over-

sensitivity of the microphone.

b. Dial 82 - 02 - # to decrease the Microphone Sensitivity and continue to modify as

necessary (option range is 00-15; Figure 4).

2. Speaker Volume Too Low

a. Increase the Speaker Output Level by changing Command 81 to 81 - 12 - # (option

range is 00-15; Figure 4).

3. NOTE: If the phone line is weak this command change may produce a negative condition.

4. Phone Line Receive Gain

a. Occasionally, when the phone line is below standard gain levels it is necessary to

change the IA500’s line gain control. Changing program settings in this area can

affect both speaker and microphone performance (i.e, there could be negative impacts

upon previously made IA500 settings).

b. To modify the default setting, dial 83 - (enter new value, between 01 and 15) - #

(Figure 4).
