Testing the Speaker
Testing the Speaker
The audio test plays a sample sound three times. If the monitor has two speakers, the
right speaker is tested first, followed by the left speaker.
Note — The CM10 and CM12 models have one speaker. The CM100, CM120, and CM150
have two speakers.
To test the speaker or speakers:
Step
1
In the Diagnostics menu, select the Audio Test button to start the test.
A window appears confirming that the monitor is entering the audio test
and displays the text:
Listen for three short tones. If your monitor has two
speakers, the three tones will repeat.
2
Verify that three short tones sound for each speaker.
When the test completes, the window closes.
