Tips for best results
o Avoid blocking the microphone or shuffling paper near the microphone.
o Avoid placing the speakerphone where it can detect excessive background noise, especially
during Speech Training mode.
o Avoid moving the telephone during a call—this changes the room's acoustic properties. If the
telephone or microphone is moved, you may have to force the Speech Training mode.
