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.
Notes:
• Power Fail Back-Up mode will not work if the
handset battery power is not sufficient (usually
not lower than level ).
• Do not pick up the power supplying handset from
base when Power Fail Back-Up mode is activated.
• Do not touch the charging contacts of the power
supplying handset during Power Fail Back-Up
mode.
• In Power Fail Back-Up mode none of the base
functions, including the answering machine will
operate.
• It may take up to 90 seconds to transition through
the Power Fail Back-Up activation process as the
