Power Fail Back-Up - VTech 15450 User Manual

POwER fAIL BACk-UP

VTech's Power Fail back-up system lets you make calls
during a mains power interruption with your cordless
phone. During a mains power interruption, you can
supply the power stored in your handset battery to the
base unit, so you can make calls even when the power is
out.
Make a call using Power Fail Back-Up mode:
If there is only one handset registered to the base:
1. Once the handset is placed onto the main base unit,
enter the telephone number, and then press
. The speakerphone will be turned on
automatically and call is made.
Notes:
• If there is more than one handset registered to the
base, the handset on the main base unit should be
left as a power supply of the base and you can use
the other handset(s) to make calls like normal.
• The handset should always remain on the main
base unit for the entire length of the call.
