The CALLMASTER VI can be administered with many features that are accessible only from your PC. Careful consideration of which features are assigned to these buttons will make your CALLMASTER VI more useful when your PC is not available.

Note: One possibility is to administer these buttons as abbr-dial numbers for use when the PC is not available to provide dialing.

Headset On/Off Button

The CALLMASTER VI does not have a physical switchhook or an integrated handset cradle. Instead, you press the Headset On/Off button to toggle between the on-hook condition and the off-hook condition.

On the CALLMASTER III, plugging the headset into the jack puts the CALLMASTER III off-hook. Unlike the CALLMASTER III, plugging the headset into the CALLMASTER VI does not affect the headset On/Off function. You can remove your headset without toggling the on-hook/ off-hook condition.

The red status indicator associated with the Mute button serves as an indicator for the Headset On/Off function. When the CALLMASTER VI is first powered up, and after a reset, the headset is in the on-hook condition. When the headset is on-hook, the status indicator is red, meaning the voice path to the headset is turned off.

When the headset is off-hook, the status indicator is dark, and the voice path to the headset is fully functional.

This button is not administerable.

Mute Button

The purpose of the Mute function is to electronically disconnect the microphone so that the caller cannot hear you if you want to speak to someone else in the room.

Use the Mute button to toggle the mute function on and off. When the voice terminal is muted, the red status indicator is flashing on for

50 ms, and then off for 200 ms.

NOTE: Going on-hook ends mute, so the lamp will go from flashing to steady on.

This button is not administerable.
