If your cordless phone does not seem to operate properly, please check the
following and refer to the appropriate sections in this booklet for detailed
information:
• The phone is dead; no indicator lights are on: Are the power
adapter and telephone cord connected?
• Handset beeps during conversations or when away from the base:
The batteries need recharging; return the handset to the base for
overnight recharging.
• Hearing poor audio or added interference during calls: Don’t cover
the top section of the handset with your hand or rest the phone on
your shoulder. This blocks the special internal Cobra
Intenna
handset antenna.
• Handset disconnects, loses performance and/or beeps three times
when in use away from the base: You may be out of range or your
batteries may need recharging. Move closer to the base and/or
recharge batteries.
• Unable to make a call due to interference: Select a new channel.
• Handset won’t work after a power outage or after disconnecting
phone from AC power and then reconnecting it: Return the
handset to the base for about 15 seconds to automatically match the
security coding.
• Handset seems "dead.": Battery power has run out; return handset
to base and charge for at least 12 hours. If handset still seems dead,
unplug the handset battery for 15 seconds and plug back in and then
place the handset back on the base for at least 5 minutes. Check that
charge LED lamp is illuminated.
• Memory dialing does not work: Handset battery may have become
completely discharged; recharge handset in cradle (12 hours) then re-
enter your memory dialing numbers (see p. 10).
• Power Failure Reset: Power Protector™ Circuitry will preserve the
codes set in the handset and base, however, if the battery in the base
is low in power, you must return the cordless handset to the base for
about 15 seconds. This automatically matches the digital security
codes.
