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 configuration 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).
