A. Use only the battery pack supplied with the unit or identical replacement.
B. Do not dispose of battery pack in a fire. The cells may explode. Check with
local codes for possible disposal instruction.
C. Since released electrolyte is corrosive and may cause damage to eyes or
skin and may be toxic if swallowed:
C1. Do not open or mutilate battery pack.
C2. Always replace the entire battery pack rather than reusing one or
more cells.
C3. Do not expose batteries to heat or flame.
D. Exercise care in handling the battery pack in order not to "short" the battery
contacts with conducting materials such as rings, bracelets, and keys. The

D. Properly dispose of "dead" batteries as soon as possible since "dead"
batteries are more likely to leak in a product.
E. Do not store this product or the battery provided with or identified for use
with this product in high-temperature areas. Batteries that are stored in a
freezer or refridgerator for the purpose of extending shelf life should be
protected from condensation during storage and defrosting. Batteries

U.S. PATENT 4876709
U.S. PATENT 5351284
Introduction
Thank you for your purchase of a Cobra®
the world’s first and only full-range-power cordless telephone without any
external antennas!
No more extending, bending, or breaking the antennas found on other
cordless phones — your Cobra
the handset and base, where they should be, out of your way.
Now you can install your new Cobra
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.
Your new Cobra Model CP-2505 has 25 selectable channels (the maximum
number available) for optimum interference-free use, and 10-number memory
dialing. The CP-2505 is also equipped with an extra-life battery which allows
you to keep the phone away from the base for up to 14 days between recharges,
Clear Call® PLUS Circuitry with compander noise-reduction system to
ensure corded-phone sound quality, Private Call™ voice scrambling, and
Power Protector™ reserve power for operation during power outages.
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
Intenna

NOTE: The advanced channel scanning technique employed by the
CP-2505 ensures that a clear channel is chosen. The TALK button
flashes during scanning. In the presence of radio interference (such as
another cordless telephone or baby monitor) there may be slight delay
in accessing the line when placing a call.
NOTE: Some cordless telephones operate at frequencies that may cause
interference to nearby TV's and VCR's. To minimize or prevent such interference, the base of the cordless telephone should not be placed near or on top of
TV's or VCR's. If interference is experienced, moving the cordless telephone
base further away from the TV or VCR will often reduce or eliminate the
interference.
CAUTION: Any changes or modifications not expressly approved by Cobra
could void the user's authority to operate the equipment.

OUT-OF-RANGE SIGNAL
If three beeps are heard immediately after the TALK button is pressed, the
handset is too far away from the base. The handset and TALK indicator will
automatically turn off. Move closer to the base and then try your call again.
POWER PROTECTOR™ SYSTEM
Although the handset is battery powered, the base obtains its power from the
AC outlet. No AC, no power. This could be of critical importance should an
emergency occur during a power failure. Many homes are now exclusively
cordless, leaving them without means to quickly contact emergency services
in this situation.
Power Protector helps solve that problem. In the
Intenna
CP-2505, a 9 volt
battery allows the base to continue working in the event of a power failure.
The phone will be usable for up to 2 hours continuously (and up to 3 hours
with occasional use)–long enough in most cases for the power to be restored.
Replacement of the Power Protector battery with a fresh high quality
alkaline battery is recommended every six months and after a power outage
over 30 minutes. Please refer to page 6 for instructions.
PRIVATE CALL™ VOICE SCRAMBLING SYSTEM
This feature is automatically activated whenever you use your phone. Built-in
voice scrambling allows complete calling privacy by scrambling the signals
between the handset and the base and between the base and the handset,
making it unlikely that an outside source such as another cordless phone,
scanner or baby monitor to pick up a conversation from your phone. This
ensures that you will always have totally private telephone conversations.
PULSE/TONE SWITCH

dialing (see switch on back of the base) depending on which
service you are using. Mixed PULSE and TONE dialing may

Rechargeable Handset Battery Information
NOTE: Before using your new Cobra

2. A warning (2 beeps every 30
seconds) 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 handset has been away from
the base and needs recharging, it
will beep at 30 second intervals for
five minutes. After this time, the
handset will seem "dead". It will
not flash or beep, nor will you be
able to get a dial tone. Return
handset to base for recharging.
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.
REPLACING THE HANDSET BATTERY
The rechargeable NiCad battery in your cordless phone may need to be
replaced if the handset will not function when the TALK button is pressed
after recharging for 12 hours.
Replacement batteries are available direct from Cobra (see accessories order
form at the end of this booklet or call 1-773-889-3087).

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: 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
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 reenter 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.
