Operating range
This cordless telephone operates with
the maximum power allowed by the
Federal Communications Commission
(FCC). Even so, this handset and
telephone base can communicate over
only a certain distance - which can vary
with the locations of the telephone base
and handset, the weather, and the layout
of your home or office.
When the handset is out of range, the
handset displays Out of range OR no
power at base.
If there is a call while the handset is out of
range, it may not ring, or if it does ring,
the call may not connect well when you
press
HOME/FLASH. Move closer
to the telephone base, and then press
HOME/FLASH to answer the call. If
the handset moves out of range during
a telephone conversation, there may
be interference. To improve reception,
move closer to the telephone base.
