General Setup Tips

Tips for Obtaining Optimal Acoustic Performance

• To minimize echoes, place the Conference Phone at the center of the room, or at least away from

walls (at least 20 inches/0.5 m from any wall).

• It is important to place the Conference Phone on the surface where it will be used before applying

power. When power is applied to the Conference Phone, it emits a series of self-test tones to auto-
matically calibrate its performance for the acoustic environment. 

• If you significantly change the acoustic environment (for example, by placing the Conference Phone in

a different location), cycle the power (unplug the power adapter, then plug it in again). This allows
the Conference Phone to adapt to its new surroundings and deliver optimal performance.

• Do not move the Conference Phone during a conversation.

• Use the Conference Phone in an environment as free as possible from background noise.

• Whenever possible, keep items that could cause noise or acoustic interference away from the

Conference Phone and (if used) External Microphones. Items that could compromise audio quality
include plants, cups, and papers near the microphones.

• Have speakers direct their voices toward the Conference Phone or (if used) External Microphone.

• Speak at normal conversational volume.

• To obtain best audio quality, adjust the microphone setup for the room size and arrangement:

– In a small, closed room without sound-absorbing walls, use the microphone selection switch to

activate only one of the Conference Phone’s built-in microphones.

– For large rooms and irregular layouts (such as L-, U-, and T-shaped conference tables), connect

External Microphones (EM-101 purchased separately). 

Selecting Number of Built-in Microphones That Will Be Active

The user can select how many of the Conference Phone’s built-in microphones 
will be active - one, two, or all three. The factory setting is three, but in
smaller rooms and asymmetric conference arrangements, better audio
quality sometimes can be obtained by deactivating one or two of the built-in
microphones. The microphone selection switch is located on the underside
of the Conference Phone, and is labeled “MIC SW.” 

With setting 3 (the factory default), all three microphones are active. With
setting 1, only the microphone by the keypad is active. With setting 2, the
microphones in positions 1 (by the keypad) and 2 are active.
