CONFIGURATION SETTING
The electronic configuration of telephone systems can vary.
You can optimize the performance of your Amplifier by stepping
through the four configuration settings. The Configuration Dial
is located on the right side of the Amplifier behind the Handset
Jack.
Place a call to a co-worker and while speaking turn the
Configuration Dial clockwise until you achieve the best sound.
A paper clip can be used to make turning the compatibility dial
easier.
Experimenting with these four settings will not harm the amplifier
or your telephone.

EarCons AUDIBLE CUES
Your Amplifier provides both visual and audio feedback for all
operator adjustments. EarCons provide audio feedback in the
form of different toned beeping sounds for different functions.
Double beeps indicate the ends and mid point ranges of each
function.
The intensity of the EarCon Audible Cue can be increased,
lowered, or turned off (Three levels plus Off).
Simply hold down the Mute Bar then depress the Volume
Rocker Switch ( decreases volume or turns off EarCon;
increases EarCon Volume).
Even though the user hears the EarCon, the calling party
does not.
