Caller ID
Liquid damage
Caution:
L To avoid permanent damage, do not use a microwave oven to speed up the drying process.
Problem Cause/solution
Caller information is not displayed. L You must subscribe to a Caller ID service. Contact
your service provider/telephone company for details.
L If your unit is connected to any additional telephone
equipment, remove and plug the unit directly into the
wall jack.
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 Other telephone equipment may be interfering with
this unit. Disconnect the other equipment and try
again.
Caller information is slow to display. L Depending on your service provider/telephone
company, the unit may display the caller’s
information at the 2nd ring or later.
L Move closer to the base unit.
Time on the unit has shifted. L Incorrect time information from incoming Caller ID
changes the time. Set the time adjustment to
“Manual” (off) (page 16).
Problem Cause/solution
Liquid or other form of moisture has
entered the handset/base unit.
L Disconnect the AC adaptor and telephone line cord
from the base unit. Remove the batteries from the
handset and leave to dry for at least 3 days. After the
handset/base unit are completely dry, reconnect the
AC adaptor and telephone line cord. Insert the
batteries and charge fully before use. If the unit does
not work properly, contact an authorised service
centre.
