The GIGAPHONE uses the spare battery charger in the Base Unit to provide
operational backup in the event of a power failure. With the a fully charged
battery pack in the spare battery charger, you will still be able to place and
receive calls from the Handset for up to one hour. During Power Backup mode,
you will not be able to use the Base Unit.
The spare battery pack can also be used to replace a drained handset battery,
ensuring uninterrupted use.
NOTE :
When using the GIGAPHONE during Power Backup mode, audio quality may
be compromised due to reduced power availability.
Open the spare battery charger
by pressing the release button,
located on the left-hand side of
the Base Unit. A drawer will
open to reveal the spare battery
compartment.
Place a battery pack in the
drawer with the charge contacts
facing up and to the right.
Push the drawer closed.
The spare battery takes 24 hours to
fully charge a drained battery.
