seconds, then attempt to make the call again. During this 45 second waiting period,

the Auto Redial LED will blink, and the unit will beep every 15 seconds.

Enhanced Full Duplex Speakerphone

The sound quality of a speakerphone is highly dependent upon both the telephone

line condition and the acoustic surroundings of the room. In order to get the best

sound quality from your speakerphone, avoid surroundings that tend to degrade the

performance such as:
* glass top surfaces
* large glass windows close to the speakerphone
* vaulted ceilings
* non-carpeted floors
* fan noise from laptops, projectors or ventilation systems (on either end of the call)
Your new speakerphone is designed to adapt, as much as possible, to these unfriendly

surroundings by performing a “self- calibration” at the beginning of each speakerphone

conversation.
1. This calibration samples the sound from both sides of the conversation. Depending

upon the surroundings and the conversation, this calibration may take up to 30

seconds to complete. Typically the calibration will complete in less than 10 seconds.

2. During this calibration, both parties in the conversation may hear a faint echo, which

will fade off as your speakerphone adapts itself to its surroundings and the condition

of the phone line.

3. If the surroundings change during the conversation (such as the speakerphone being

moved) the calibration will adjust accordingly. This adjustment samples both sides of

the conversation again, and may result in a temporary faint echo for several seconds.
