Speakerphone Performance Tips
The speaker on your system phone has a sensitive sound-activated switch. Room
acoustics and background noise can affect the proper operation of the
speakerphone. To ensure that your speakerphone works effectively, follow these
guidelines:
Avoid placing your phone in areas with high background noise caused by
sources such as motor vehicles, manufacturing equipment, loud voices,
radios, printers, copiers, typewriters, other noisy office equipment, and
heater and air conditioning fans.
Avoid talking before the other person is finished speaking. When you both
talk at the same time, only one person's voice comes through.
Do not use your speaker to make announcements over a loudspeaker
paging system connected to your phone system.
When talking, always face your phone and stay within two feet of it.
Place your phone at least six inches (15 cm) away from the edge of your
desk.
If you have difficulty hearing the other party, try increasing the speaker
volume. If you have background noise, try turning off the microphone when
the party at the other end is speaking and turning it on when you speak. If
the difficulty persists, lift your handset to continue the conversation.
In conference rooms, a separate speakerphone (such as the
SoundStation® from Lucent Technologies) is recommended, since the
built-in speaker on a system phone is designed for individual use.
