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
Aer 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 aer the 
power goes out, all handsets show Out of range OR no power 
at base and Put HS on base to power base, alternately. 
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, alternately, aer 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, we recommend that you do not 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 li 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.
