Adding or Removing Hardware

7.If the echo still exists, set the EC Configuration: field to 1, 2, or 3, then test the voice quality. These settings provide help for the following scenarios:

●Setting 1 rapidly minimizes echo when first detected, regardless of the loudness of the talker’s voice. Settings 1 and 4 have the same EC settings except that Setting 1 introduces 6 dB of loss.

●Setting 2 minimizes speech clipping, but it takes a fraction of a second longer for the echo to fade.

●Setting 3 eliminates speech clipping, but a strong echo may take 2 or 3 seconds to fade.

8.If after trying all these settings, the echo still exists, contact technical support. Refer to Where to get additional help on page 22.
