Handset Signal Detection

You can monitor the handset signal strength while moving to different locations. The antenna/signal strength and battery icons appear on the handset display.

When you move too far from the base station, the following occurs on the handset:

the antenna/signal strength icon disappears

Out of range... message appears

handset produces an intermittent beep

handset may go into scanning mode

If the signal strength is weak, move back into range to stop the handset display messages and warning tones.

If you go completely out of range during an active call, the call is automatically placed on hold. For more information, refer to Hold calls on page 43. Retrieve a held call by selecting the flashing red line button when you are back in range.

Note: In cases where the line button does not light when you move back into range of the base station, press the intercom/line button that the call came in on, to take the call off hold.
