Cause/solution
L You are using the handset or base unit in an
area with high electrical interference. Re-
position the base unit and use the handset
away from sources of interference.
L Move closer to the base unit.
L If you use a DSL/ADSL service, we
recommend connecting a DSL/ADSL filter
between the base unit and the telephone line
jack. Contact your DSL/ADSL provider for
details.
L Unplug the base unit's AC adaptor to reset the
unit and turn off the handset. Reconnect the
adaptor, turn on the handset and try again.
L You have registered a handset that is not
recommended (page 4). The clearest sound
quality is only possible by registering the
recommended handset.
L The ringer volume is turned off. Adjust ringer
volume (page 21).
L The dialling mode may be set incorrectly.
Change the setting (page 13).
L The handset is too far from the base unit.
Move closer and try again.
L Another unit is in use. Wait and try again later.
L The key lock feature is turned on. Turn it off
(page 17).
