Getting started

Battery backup mode

Battery backup mode allows your telephone system to function in the
event of a power outage. The telephone system uses stored power from the
handset's battery to operate.

To activate the mode

After the power goes out, if there is already a handset with
enough charge placed in the telephone base, the telephone
system enters battery backup mode automatically. That handset
screen shows Powering base... Don't pick up. All other
handset screens show Battery backup mode.
-OR-
If there is no handset placed in the telephone base after the
power goes out, all handsets show Out of range OR no power
at base and Put HS on base to power base alternatively.
Place any handset with enough charge in the telephone base.
Its screen shows Powering base... Don't pick up. All other
handset screens show Battery backup mode.
NOTE: A handset which does not have enough charge to power up the
base, its screen shows Out of range OR no power at base and Not
enough battery to power base alternatively after the power goes out.
Find another system handset that has enough charge to activate the
mode.

Operation

During battery backup mode, the telephone base, answering system and all
Bluetooth related features will be disabled. The operating time is subject
to the battery level of the handset placed in the telephone base and the
actual usage. For optimal performance, you are not recommended to use the
handset placed in the telephone base when this mode is on.
Using other system handsets (Recommended):
Operate the handsets the same way as usual, except the answering system
and all Bluetooth related features which will be disabled.
Using the handset placed in the telephone base:
To maximize the operating time, you are not advised to use this handset. If
you do have to use it, make sure you do not lift it from the telephone base.
All operations should be done with the handset placed in the telephone base.
In this case, calls can only be made and received using the speakerphone.
