SUGGESTION
Check the telephone line cord connectors at both ends
that they are pushed in firmly until they click.
If you had a power failure or had unplugged the base
unit, replace the handset on the base unit for two to five
second to reset the system.
You may have exceeded the Ringer Equivalence Number
(REN) limit of how many phones can be connected to the
same line. The REN total of all devices (printed on the
label on the bottom of each unit) should not exceed three
(3). Disconnect the appropriate units to lower the REN
total.
Check the Nickel-Cadmium battery connection inside the
main battery compartment on the handset.
The handset rechargeable Nickel-Cadmium battery pack
may need to be charged.
Make sure the charging contacts on both the base unit
and the handset are in contact during charging.
The charging contacts may need to be cleaned.
Refer to page 9.
The Nickel-Cadmium battery may need to be discharged
first before a full charge.
Move the base unit so that it is centrally located in your
residence or office and make sure that the base unit is not
located near appliances.
The handset rechargeable Nickel-Cadmium battery may
need charging.
You may be out of normal operating range. Move closer to
the base unit.
