Troubleshooting
If you still have difficulties after following the instructions in this section, disconnect the base unit's
AC adaptor, then reconnect the base unit's AC adaptor. Remove the batteries from the handset,
and then insert the batteries into the handset again.
General use
Problem
The handset does not turn on
even after installing charged
batteries.
The unit does not work.
The handset display is blank or
dark.
I cannot hear a dial tone.
Programmable settings
Problem
The display is in a language I
cannot read.
While programming, the
display returns to standby
mode.
I cannot register a handset to a
base unit.
Cause/solution
L Place the handset on the base unit or charger to turn on
the handset.
L Make sure the batteries are installed correctly (page 11).
L Fully charge the batteries (page 11).
L Check the connections (page 10).

Reconnect the adaptor and try again.

the handset display again by:
– pressing {3} or {4} when on a call.
– pressing {OFF} at all other times.
L "LCD in charging" is set to "Off" while on charge.
Change the setting (page 24).

connected. Check the connections.
L Disconnect the base unit from the telephone line and
connect the line to a known working telephone. If the
working telephone operates properly, contact our service
personnel to have the unit repaired. If the working
telephone does not operate properly, contact your service
provider/telephone company.
Cause/solution
L Change the display language (page 14).

received. Wait and try again later.
