Low Power Mode

Radio link/connection status Information

Dialed digits displayed

Visual dial tone indicator

Service messages (described in Chapter 4)

Dial Pad

The Pocket Phone Dial Pad consists of the standard 12 buttons for dialing telephone numbers and accessing the DEFINITY ECS call features.

Low Battery Indicator

When the battery power is low, the pocket phone emits a warning tone and the LOW BATT message appears on the Pocket Phone Display.

Low Power Mode

This feature conserves battery power. If the Pocket Phone is within a coverage area, and if no local activity has taken place for three minutes, the Pocket Phone powers down and the display is blank. Any unfinished soft key input is lost when the Pocket Phone powers down.

If the Pocket Phone becomes linked to a System after power down, the normal display screen is activated.
