BT 90 - Manual (Page 31)

In the event of a power failure
During a power failure, if you have
fitted a fresh alkaline back-up battery
in the base unit, your telephone will
continue to work for up to one hour in
use or seven hours on standby.
When power has been restored,
you are advised to renew the back-
up battery in the base unit, though
this should not be necessary if the
power has only been disconnected
momentarily.
Care of rechargeable battery
pack
• When you first setup the Freestyle
90, or replace the battery pack, the
handset must be fully charged for
24 hours before use.
• To maintain optimum charge and
battery condition, the handset
should be allowed to fully
discharge about every four months.
• Dispose of Ni-Cad battery packs
safely.
Do not puncture or burn them.
They contain toxic materials
which could cause injury.
General cleaning
Clean the cabinet of the handset
and the base unit with a soft cloth
slightly dampened with a mild
solution of water and detergent.
Charging contacts should be
cleaned with a dry cloth or, for
heavy soiling, a pencil eraser can be
used.
• Do not clean with a wet cloth.
• Do not clean with abrasive
materials or solvents as these
may damage the unit.
• Do not spray aerosol cleaners
onto the base unit or handset.
Extended periods of non-use
It is recommended that you:
• Disconnect the base unit from
both mains supply and telephone
line.
• Remove the back-up battery from
the base unit and handset.
• When reconnecting, check that
the
CHARGING light on the base
unit is on. Recharge the handset
battery for 24 hours.
