SOLUTION
Check that the telephone line cord connectors at both
ends are pushed in firmly until they click.
If you had a power failure or had unplugged the base
unit, return the handset on the base unit for two to five
seconds to reset the system.
Check to see if the RINGER switch is set to OFF.
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 bottom label of each unit) should
not exceed five (5). Disconnect the appropriate units to
lower the REN total.
Check to see if you have programmed a number to be a
blocked call. Refer to the "BLOCKED CALLS" section of
the manual.
Check for the Ni-Cd battery pack connection inside the
battery compartment on the handset.
The handset rechargeable Ni-Cd battery pack may need
charging.
Make sure the charging contacts on both the base unit
and the handset are in contact during charging.
The charging contacts may need cleaning with an
alcohol-moistened cloth or pencil eraser.
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 Ni-Cd battery pack may need
charging.
Choose an alternate channel using the DEL/CHAN
button on the handset.
