Enhanced Speakerphone Mode
The Enhanced Speakerphone Mode improves transmission quality while on a speak-
erphone call over a limited volume level range (typically the range is 1 to 3).
To use this feature, the System Administrator or installer must program your
phone for Enhanced Speakerphone Mode. This feature is not available on the 8660
To enable enhanced speakerphone mode while on a call:
. The speakerphone will return to standard mode
when you end the call.
There will be about one second of white noise while the speakerphone circuitry is cal-
ibrated to the call. (Both parties should avoid speaking during this white noise.) If the
speakerphone cannot be calibrated correctly, the display shows CANNOT ENABLE
Two Display Phones cannot be in enhanced mode while on a call together; one
phone must be off-hook to allow the other phone to enter enhanced speakerphone
mode. Also, on some long-distance calls, the outside party may hear his or her own
echo when speaking to a Display Phone. If the amount of echo is objectionable, do not
use the Enhanced Speakerphone Mode.
