shock and injury to persons, including the following:
1. Read and understand all instructions.
2. Follow all warnings and instructions marked on the product.
3. Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for
cleaning.
4. Do not locate base unit near water, for example, near a bath tub, wash bowl, kitchen sink, or laundry tub, in a wet basement or
near a swimming pool.
5. Do not place this product on an unstable cart, stand or table. The product may fall, causing serious damage to the product.
6. Slots and openings in the cabinet and the bottom or back are provided for ventilation, to protect it from overheating; these open-
ings must not be blocked or covered. The openings should never be blocked by placing the product in the bed, sofa, rug or other
similar surface. This product should never be placed near or over a radiator or heat register. This product should not be placed
in a built-in installation unless proper ventilation is provided.
7. This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the
type of power supply to your home, consult your dealer or local power company.
8. Do not allow anything to rest on the power cord. Do not locate this product where the cord will be abused by persons walking
on it.
9. Do not overload outlets and extension cords as this can result in the risk of fire or electric shock.
10. Never push objects of any kind into this product through cabinet slots as they may touch dangerous voltage points or short out
parts that could result in a risk of fire or electric shock. Never spill liquid of any kind on the product.
11. To reduce the risk of electric shock, do not disassemble this product, but take it to qualified servicemen when service or repair
work is required. Opening or removing covers may expose you to dangerous voltages or other risks. Incorrect reassembly can
cause electric shock when the appliance is subsequently used.
12. Avoid using telephones (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from
lightning.
13. Do not use the telephone to report a gas leak in the vicinity of the leak.
14. Unplug this product from the outlet and refer servicing to qualified service personnel under the following conditions:
A. When the power supply cord or plug is damaged or frayed.
B. If liquid has been spilled into the product.
C. If the product has been exposed to rain or water.
D. If the product does not operate normally by following the operating instructions. Adjust only those controls that are covered
by the operating instructions because improper adjustment of other controls may result in damage and will often require exten-
sive work by a qualified technician to restore the product to normal operation.
E. If the product has been dropped or the cabinet has been damaged.
F. If the product exhibits a distinct change in performance.
15. Never install telephone wiring during a lightning storm.
16. Never install telephone jacks in wet locations unless jack is specifically designed for wet locations.
17. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
CAUTION:

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 battery or conductor may overheat and cause burns.

Frequently Asked Questions
(FAQ) can be found on-line at:
www.cobraelec.com
Frequently Asked Questions
27
1.How long should the handset battery be
charged?
Typically leaving the handset on the base
overnight will charge the battery sufficiently.
2.How long can a battery last after a twelve
hour charge?
After a twelve hour charge, the handset has typi-
cally 8 hours of continuous talk time,or 7 days in
standby mode (when the phone is out of the
base but not in use).
3.What is the range of my cordless phone?
There is no way to easily answer this question as
many factors affect the range of a cordless
phone. In an open field, under ideal conditions,a
900 MHz cordless phone can have an effective
range of about 1200 feet.
Unfortunately,most cordless phones are used
under conditions that are anything but ideal. The
effective range of a cordless phone varies
because of environmental and other conditions.
Cordless phones and other 900 MHz devices may
cause interference which may limit the effective
range of your cordless phone. Changing the
channel may help.
Aluminum siding can also have a dramatic effect
on range.Try using your cordless phone in many
locations in and around your home. Each situa-
tion presents different conditions under which
the phone must work.
Phone is dead
Are power adapter and phone cord connected?
Handset beeps during call or away from base
Batteries need recharging; return handset to base.
Handset disconnects,loses performance and
beeps three times when in use away from base
Out of range or batteries need recharging.
Move closer to base or recharge batteries.
Unable to make call because of interference
Select a new channel.
Handset won’t work after power outage or
disconnecting from AC power & reconnecting
Return handset to base for thirty seconds to
automatically match 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 handset battery for 15 sec-
onds and plug back in. Then place handset back
on base for at least 5 minutes.
Memory dialing not working
Batteries need recharging; return handset to base.
Re-enter memory numbers.
CP9105 manual layout.8 10/14/98 9:28 AM Page 31

Frequently Asked Questions
28
5.Why do I have static on my cordless phone?
Your cordless phone works as a miniature radio
transmitter and receiver.As such,it will pick up
stray signals caused by other nearby appliances
which emit radio signals and thus become a
source of interference.
Some sources in a home that may cause noise
and interference on a cordless phone are:
• other cordless phones
• fluorescent fixtures
• home appliances such as televisions,
refrigerators,microwave ovens,
home computers and baby monitors
In order to eliminate some of this interference
it may be necessary to relocate the base unit of
the cordless phone to a different location in your
house.This solves two problems.First,you are fur-
ther from the source of interference and secondly
the power adapter for the cordless phone will be
plugged into an outlet, which most likely is on a
different line than the appliance which is causing
the interference.
If the noise persists after relocating the base,
move closer to the base unit when talking on the
phone.If the noise disappears,then it is most like-
ly local interference being generated by a source
outside your home, or a source inside your home
strong enough to blanket your entire house such
as a baby monitor.If you find that the noise and
interference are equally strong throughout your
house,your cordless phone may require service.
Frequently Asked Questions
29
4.Why do I sometimes have difficulty making a
connection even though I’m close to the base?
There are several possible causes for this condi-
tion.Please try the following solutions to see
where your problem lies.
First,make sure the base unit power adapter is
connected to a working AC outlet. Make sure
that you are within range of the base unit when
pressing the TALK button.If this works, then you
were trying to access the base from too great a
distance.Other cordless phones in your house
could be causing interference.Two or more
cordless phones may interfere with each other’s
security codes. If you have two or more cordless
phones in your house please disconnect all but
the phone which is giving you the Out of Range
signal.You can then reset the security codes by
using the following procedure.
To reset the security code,remove the handset
from the base.Remove the power cord from the
base for 30 seconds. Replace the power cord to
the base and replace the handset,making sure
the charge light comes on. Wait another 30 sec-

still be used but they should be moved further
apart or you may experience this problem again.

each other.Problems you could experience
include:
