If the battery runs low while a call is in progress, the handset beeps once every three seconds.

If the battery is low while the telephone is in Standby Mode:

•Handset beeps every 15 seconds for 3 minutes

•None of the buttons operate

•Handset cannot make or receive calls

•Battery Charge icon indicates the current state of the handset’s battery. When the icon reduces to one bar, return the handset to the cradle or swap the battery with a charged one.

It is recommended that you have a spare battery always charging to ensure against complete battery discharge. See “Charge the Spare Battery” on page 28 for more information.
