BASIC LEVEL CHECKS AND SELF TESTS: Self-Test Procedures

Required equipment: reference unit

The Call Performance test time is approximately 7 minutes:

1.Power up the unit. Wait until registration is complete before continuing.

2.Place an interconnect call from the problem unit to the reference unit.

3.Ensure that both units have a signal strength of 3 bars or more.

4.Press Menu > Settings > Volume (Speaker Volume), and use the Volume keys to set the speaker volume of the problem unit to 3 bars.

5.Verify that the problem unit performs within audio-quality standards. If defects such as distortion, hum, or screeching exist, replace the unit.

6.Place a dispatch call to another unit in the group.

If defects such as distortion, hum, or screeching exist, replace the unit.

7.To automate this test, turn on the Auto Answer menu setting (Menu > Settings > Phone Calls) in the reference unit and place the unit next to a good source of voice audio, such as a tape- recorded speech.
