Verify the voltage at the speaker assembly when in use; it should be between -18 to -24VDC. 3. Use a lineman's test set to check the audio level on the Tip and Ring leads.

      If you're experiencing a loud squeal (feedback) from your Valcom Speakers, try the following: * Reduce the speaker's volume by turning it counter-clockwise. * Increase the distance between the telephone and the speaker. * Consider installing a noise-canceling handset on the telephone, especially in areas with severe feedback problems. * You might also consider adding a V-9964 Digital Feedback Eliminator.
