Other Configuration Settings:

Compatibility: If you cannot hear a dial tone through the headset, your caller cannot hear you, or you hear buzzing or hissing in the headset, you should adjust the compatibility setting. To do so, use a coin or small screwdriver to turn the Telephone Configuration Dial on the left side of the base unit (see below) until the audio issue is resolved. Make sure the number is aligned to the position indicator.
Call Auto-Answer/Call Control (IntelliStand Switch): If you want to answer a call or trigger a dial tone by pressing the call control button on the headset, set the IntelliStand switch on the right side of the base unit (see below) to the off position (-). If you want to trigger a dial tone or automatically answer a call by taking the headset out of the base charging cradle, set the IntelliStand switch to the on position (=).
