Ten minutes before the battery charge level gets too low to operate the handset, an
empty battery icon will start flashing, five short tones are generated and a Low

dropped.

After a low battery indication, place the handset in the charger and make sure the
CHARGING light turns on. With the exception of the first charge, the battery typically
takes eight hours to fully charge.
