systems inside the handset and base, where they should be, out of your way.
Now you can install your new Cobra INTENNA cordless phone virtually any-
where. Without cumbersome external antennas to worry about, put your new
phone anywhere a corded phone can go! Then enjoy the freedom of using
your new cordless phone all over the house as well as outside in your yard.

system ensures corded-phone sound quality.

Please take a moment to review this booklet and become familiar with all of
the many user-friendly convenience features built into your new Cobra INTEN-
NA Cordless Phone.
If you need further assistance installing or using your new phone, please call
our toll-free consumer “hotline” at 1-800-COBRA 22 between 8:30 a.m. and
5:00 p.m. (Central Time) Monday through Friday.
Installation Information
Your Cobra INTENNA Cordless Telephone without any external base or handset
antennas offers many new installation choices compared to traditional cordless
phones with telescopic antennas. Your new phone can be located under cabi-
nets, next to lamps, on crowded countertops and in other tight spaces that were
previously inaccessible to cordless phones.
Maximum range is obtained by installing the base unit in the highest living area
of your home. The location you choose must be near an electrical outlet and a
telephone wall jack. (To minimize electrical interference, avoid plugging your
cordless phone into the same electrical outlet that has a charging unit for a
cordless vacuum, screwdriver or other electronic device.)
Operational Features
Using Your Phone
After charging the handset batteries overnight (at least 12 hours), use your
Cobra INTENNA cordless phone like any corded phone. With Cobra’s AUTO
STANDBY feature, just pick the handset up to answer or place a call.
The following features offer state-of-the-art performance and the ultimate in
user-friendly convenience with your new Cobra INTENNA cordless telephone.

Press and release the TALK button when finished with a call in order to
“hang up” the phone.
You may need to change channels if you experience interference (noise, static,
or poor audio):
•
With TALK light on, press and release the CHAN button on the handset
to advance to a new channel. A series of beep tones (2 groups of 2
beeps) will sound to indicate successful channel change.
•
An alert tone (three beeps) will sound if a new channel is unavailable
due to interference. In that case, move closer to your cordless base and
try to change channels again.

DIGITAL SECURITY CODING
If three beeps are heard immediately after the TALK switch is pressed, the hand-
set is too far away from the base. The handset and TALK indicator will automat-
ically turn off. Move closer to the recharging base and then try your call again.
Your Cobra INTENNA features digital security coding (in accordance with FCC
regulations) to reduce the chance of interference from your neighbors’ cordless
phones. These inaudible, electronic codes are transmitted automatically by
your phone to establish a secure link between your cordless handset and base.
POWER FAILURE RESET
After a power failure in your home (or any time you unplug your phone from
AC power and then reconnect it), you must return the cordless handset to the
base for about five seconds. This automatically resets the matching digital secu-
rity codes and returns the channel selector to its start-up setting.

Your Cobra INTENNA cordless phone can be used with any phone system
because it is switchable from pulse to tone dialing (see switch on rear of the
base) depending on which service you are using. When using pulse dialing,
mixed PULSE and TONE dialing may be used (to access certain long-distance or
computerized banking services, for example) by selecting PULSE with the base
This feature briefly interrupts the phone line so that you may access some of the
advanced features — like “Call Waiting” and “Three-Way Calling” — that may

HEARING AID COMPATIBILITY
RINGER SWITCH
Your cordless telephone handset is compatible with inductively coupled hearing
aids.
This ON/OFF switch (located at the rear of the base) controls your cordless
handset’s electronic ringer; no ring will sound in the OFF position.
INTENNA SYSTEM
®
SECUR-LOC
The revolutionary, patented INTENNA hidden-antenna system is a Cobra exclu-
sive. Now you own the world’s first and only full-range-power cordless tele-
phone that conceals the handset and base antennas inside the phone and out of
the way. No more traditional metal antennas to extend, bend or break. Cobra’s
hidden antennas are perfectly matched to your phone’s microprocessor circuitry
for optimum performance — and they offer the ultimate in user-friendly conve-
nience.
This exclusive Cobra electronic circuitry is an added security measure to pro-
tect your phone line from being accidentally accessed by a neighbor’s cordless
phone. Secur-Loc activates automatically every time your cordless handset is
placed into its base.
LAST NUMBER REDIAL
Each time you dial, the phone number you’re calling is automatically saved in a
special REDIAL memory. To call that number again — especially useful after
receiving a busy signal — press and release the REDIAL button on the handset
and the number will be automatically redialed.

A Few Words About Cordless Phone Performance
Rechargeable Battery Information
Your Cobra INTENNA cordless phone uses radio transmission to communicate
between the base and handset. It is thus subject to occasional interference—sta-
tic or buzzing noises, for example. These conditions may be caused by electri-
cal motors on household appliances, fluorescent lights, electrical storms and
other sources.
NOTE: Before using your new Cobra INTENNA cordless telephone for the first
time, you must charge the batteries overnight (at least 12 hours) for optimum
long-life conditioning of the nickel-cadmium rechargeable handset batteries.
BATTERY RECHARGING
When your cordless handset batteries need recharging, the following warning
measures will remind you to immediately return the handset to the base for
recharging (this normally requires at least 12 hours of continuous charging):
These steps will enhance the maximum performance of your new phone:
•
Change channels by pressing the CHAN button on the handset if you
experience interference.
1) The BAT indicator on the handset will flash.
•
Don't cover the upper section of the cordless handset with your hand
(see diagram #4). This may block the internal antenna located at the top
of the handset, possibly reducing the phone's range and audio clarity.
Always hold the handset at the middle or close to the bottom.
2) A warning beep will sound while you are using the phone (this indicates
you have only a few minutes of battery power remaining to complete
your conversation before the phone disconnects).
3) When the handset has been away from the base for a few days and is in
need of recharging, the handset will beep in 30 second intervals for five
minutes. Return handset to base for recharging.
Diagram #4:
Hold the
cordless handset at the
middle or bottom area
of your phone for
best performance.
NOTE: The CHARGE indicator will remain on as long as the handset is in the
base, even after the batteries are fully recharged. The batteries will not be
damaged if the handset remains in the base continuously; the charging system
is self-adjusting and will never overcharge the batteries.
CORRECT
INCORRECT
REPLACING THE BATTERIES
Routine use of your cordless phone may deplete the rechargeable batteries in
three to four years (depending on actual level of usage). The batteries will need
to be replaced when the handset no longer accepts recharging and will not
function when the TALK button is pressed.
•
•
Avoid resting the handset on your shoulder during conversations; this
may also block the performance of the internal antenna.
Don't plug your phone's power cord into an active AC outlet that also
provides power for a major appliance or for charging units for cordless
appliances (vacuums, screwdrivers, etc.) or other electronic devices.
Replacement batteries are available from any Cobra service station or direct
from Cobra (see accessories instructions/order form at the end of this booklet).
To replace:
•
Performance of your phone may be improved by uncoiling the base
telephone cord (because the INTENNA hidden-wire antenna system is
inside the phone cord).
1) Remove the phone number display window and card.
2) Remove screw in center recessed area.
3) Use a coin in the slot at the top to carefully pry open front from back of
handset.
4) Carefully take off back of handset.
5) Unplug the connector cord and discard old batteries.
6) Position and connect new battery.
7) Put back and front together so that hooks at bottom engage. Then apply
pressure to both sections to reassemble.
8) Replace screw in center of phone number section. Return card and window
to area.
9) Put handset in base charging well and allow batteries to charge 12 hours.
