Mitel GW620 manual Opening Applications, Proximity sensor, Proximity calibration

Opening Applications

To open any Application, simply touch its icon.

Proximity sensor

When receiving and making calls, this sensor automatically turns the backlighting off and locks the touch keypad by sensing objects when the phone is near the ear. This makes the battery life last longer and prevents the touch keypad from malfunctioning through automatic key locking during calls. Users, therefore, do not have the inconvenience of unlocking the phone when searching the phonebook during calls. Proximity calibration may be needed in the event of a malfunction, for example if the screen turns off when starting to receive or make a call.

Proximity calibration

When making or receiving a call, this function resets the distance measurement performance between the phone and the ear. Please be careful not to block the proximity sensor, including the protective film and fitting case, during calibration.

WARNING

Do not place anything, such as protective film, leather cases, hands or foreign bodies over the proximity sensor, or expose the proximity sensor to moisture, at any time, including during calibration. A malfunction (i.e. a black screen and the screen turns off ) may occur when starting to receive or make calls.
