About Cordless Phone Performance
Your Cobra Intenna cordless phone uses radio transmission to communicate
between the base and handset. It is thus subject to occasional interferenceÑstatic
or buzzing noises, for example. These conditions may be caused by electrical
motors on household appliances, ßuorescent lights, electrical storms and other
sources.
These steps will enhance the maximum performance of your new phone:
• Change channels by pressing the CHANNEL button on the handset if you
experience interference.
• Don't cover the upper section of the cordless handset with your hand (see
diagram below). This may block the internal antenna located at the top of
the handset, possibly reducing the phoneÕs range and audio clarity. Always
hold the handset at the middle or close to the bottom
INCORRECT
CORRECT
• Avoid resting the handset on your shoulder during conversations; this may
also block the performance of the internal antenna.
• Avoid plugging your phone's power cord into an active AC outlet that also
provides power for a major appliance or for charging units a for cordless
appliances (vacuums, screwdrivers, etc.) or other electronic devices.
Hold the cordless
handset at the middle
or bottom area of your
phone for best
performance and range.

Troubleshooting Guide
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: DonÕt 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.
• Power Failure Reset: Power Protectorª 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.
• Caller ID does not work properly: Make sure you have subscribed to
Caller ID service from your telephone company. Check to see if messages
shown in the display correspond with those on page 10.
• Caller ID works properly but does not display information from a
second caller: Make sure you have subscribed to Call Waiting and conÞrm
that your telephone company provides Caller ID during Call Waiting.
