Your Extension's Accessories Í Ô Lx Lx ÖÔ í Operation in Headset Mode Once the headset connection has been validated, you may then, at your leisure, operate your extension either in headset or handset mode. To deactivate the headset mode: Simply press the Headset key shown on the left. When the headset mode is activated, the LED associated with the Headset key will be on. When the headset mode is activated, your calls are processed similarly to calls in handsfree mode. Therefore, to hear the dial tone before placing an outgoing call on your extension: Press a free line key. Or, to answer a new incoming call presented on your extension: Press the flashing line key on which the call is presented. Or, to disconnect a call: Press the "C" key on your extension. A new call is presented on your idle extension in the standard manner through an audible, single, discreet signal emitted over the headset, rather than your extension's usual ring, which is automatically deactivated. However, according to the programming for your facility, this signal heard in the headset may be accompanied by a repetitive signal also heard on your extension's loudspeaker. This signal is repeated every 5 seconds until you answer the call that is presented to you on your idle extension. You will be notified of a new call presented on your extension with a single ring heard over your extension's headset. This is also true for any call that is on hold. Note: The programming of your facility as described above is valid for all extensions using a headset. MD Evolution - Dialog 4223 Professional 157
