Model 8520 Display Phone User Guide
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).
NOTE: To use this feature, the System Administrator or installer must program your
phone for Enhanced Speakerphone Mode.
To enable enhanced speakerphone mode while on a call:
EITHER, Press and then .
OR, Press and dial . 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, displays show CANNOT ENABLE
ENHANCED MODE.
NOTE: 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. If the amount of echo is objectionable, do not use the Enhanced
Speakerphone Mode.
