could fall, causing serious damage or impeding operation.
❑Never place this telephone near or over a radiator or heat register.
❑Only operate this telephone using the type of power source listed on 
the marking label. If you are not sure of the power supply of your 
home, consult your dealer or local power company.
❑Do not overload wall outlets and extension cords as this can result 
in the risk of fire or electrical shock.
❑Never push objects of any kind into this telephone as they can touch 
dangerous voltage points or short out parts that could result in a 
risk of fire or electrical shock.
❑Take the phone to a qualified technician when it requires repair work 
or service. To reduce the risk of electrical shock, do not 
disassemble the telephone. Opening or removing covers can expose 
you to dangerous voltages or other risks. Incorrect re-assembly can 
cause electrical shock during subsequent use.

WARNING
Warning: To prevent fire or shock hazard, do not 
expose this product to rain or moisture.
!CAUTION
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT
REMOVE COVER OR BACK. NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED PERSONNEL.
This symbol is intended to alert you to the presence of uninsu-
lated dangerous voltage within the product’s enclosure that 
might be of sufficient magnitude to constitute a risk of electric 
shock. Do not open the product’s case.
This symbol is intended to inform you that important operating 
and maintenance instructions are included in the literature ac-
companying this product.
Important: Cordless phones generally require AC power to operate. You 
should also have a corded phone that does not require AC power to operate 
so you can still make and receive calls if there is an AC power failure.
!CAUTION
Changes or modification to this device not expressly approved by
CIDCO Communications could void the user’s authority to operate this
equipment.

BATTERIES
❑Disconnect the telephone when replacing the battery pack.
❑Use only 3.6V 600mAh Nickel Cadmium (Ni-Cd) cordless telephone 
replacement battery pack (one included with phone).
❑Do not dispose of the battery pack in a fire as it will explode. Check 
with local codes for proper battery disposal regulations.
❑Do not open or mutilate the battery pack. Released electrolyte is 
corrosive and can cause damage to the eyes or skin. It can be toxic, 
if swallowed.
❑Avoid contact with rings, bracelets, keys or other metal objects, 
when handling batteries. These objects could short out the battery 
or cause the conductor to overheat resulting in burns.
❑Do not attempt to recharge the battery pack by heating it. Sudden 
release of battery electrolyte can cause burns or irritation to the 
eyes or skin.
❑Remove the battery pack if you do not plan to use the phone for 
several months at a time. The batteries could leak over that time.
❑Discard “dead” battery packs as soon as possible because they are 
likely to leak into the phone.
❑Do not store this phone or battery pack in a high temperature area. 
Batteries stored in a freezer or refrigerator should be protected 
from condensation during storage and defrosting. Battery packs 
should be stabilized at room temperature before using.
❑Your battery pack is rechargeable and can be 
recycled once it outlives its usefulness. Depending upon 
your local and state law, it might be illegal to dispose of 
this battery into a municipal waste system. Check with 
your local solid waste company or call 1-800-8-BATTERY 
for information on Ni-Cd battery recycling and 
disposal/restrictions in your area.

FCC REQUIREMENTS
This product complies with Part 68 of FCC rules. The Federal Communi-
cations Commission (FCC) has established these rules that permit this 
device to be directly connected to the telephone network. Standardized 
jacks are used for these connections. This equipment should not be used 
on party lines or coin phones.
If this device is malfunctioning, it might also be harmful to the telephone 
network; disconnect the unit until the source of the problem is deter-
mined and the device is repaired.
If the telephone company requests information on what equipment is con-
nected to their lines, inform them of:
1. The telephone number to which this device is connected.
2. The FCC registration number and ringer equivalence number (REN) 
found on the bottom of the unit.
The FCC requires that you connect your device to the telephone network 
through a modular telephone outlet or jack. The appropriate outlet or jack 
is a USOC RJ-11C, RJ-14C, RJ-11W, or RJ-14W.
A label on the base of this equipment contains information about the FCC 
registration number and the Ringer Equivalence Number (REN). The REN 
determines the number of communication devices that can be connected 
to your telephone line. In most areas, the sum of RENs should not exceed 
5 devices. 
3. If too many devices are attached, they might not ring properly.
If you are using a cordless telephone product, some frequencies might 
cause interference to nearby TVs and VCRs. To minimize this type of 
interference, do not place the cordless base on or near a TV or VCR. If 
you continue to experience interference, move the base further away 
from the TV or VCR.
This equipment cannot be used on public coin telephone lines. Connection 
to party line service is subject to state tariffs.
This product is hearing aid compatible.

work, telephone company service calls, or any other incidental or 
consequential damages.
C.    STATE LAW RIGHTS
Some states do not allow limitations on how long an implied warranty

CARE AND MAINTENANCE
You new CL915 telephone is an example of superior design and 
craftsmanship. The following suggestions will help you care for your 
phone so you can enjoy it for years.
Modifying or tampering with the internal components of CL915 can 
cause a malfunction and may invalidate its warranty and void your FCC 
authorization to operate this telephone.
Keep the phone dry. If it gets wet, wipe it dry 
immediately. Liquids may contain minerals that can 
corrode the electronic circuits.
Use and store the phone only in normal temperature 
environments. Temperature extremes can shorten the 
life of electronic devices, damage batteries, and 
destroy or melt plastic parts.
Keep the phone away from dust and dirt which can 
cause premature wear of parts.
Handle the phone gently and carefully. Dropping it can 
damage circuit boards and cases and can cause the 
phone to work improperly.
Use only fresh batteries of the required size and 
recommended type. Batteries can leak chemicals that 
damage your phone’s electronic parts.
Wipe the phone with a damp cloth occasionally to 
keep it looking new. Do not use harsh chemicals, 
cleaning solvents, or strong detergents to clean the 
phone.

CARE AND MAINTENANCE

REPLACING THE BATTERY PACK
If you follow the instructions in “Connecting and Charging the Battery 
Pack”, the battery pack should last approximately one year. If the battery 
does not hold a charge for more than 2 hours after an overnight charge, 
replace the battery with a new 3.6 volt, 600 milliampere battery with a 
connector that fits the socket in the battery compartment.
Install the new battery pack, then charge the battery pack for about 15 
hours.
Note: To avoid losing information stored in memory, try to install and be-
gin charging the new battery pack within 2-3 minutes.
Cautions:
■You must use a replacement battery pack of the same size and 
type, with the proper connector.
■Be careful not to short the battery pack by touching it with 
conducting materials such as rings, bracelets, and keys. The 
battery pack or conductor might overheat and burn.
■Do not dispose of the battery pack in a fire because it might 
explode.
Important: This product contains a rechargeable nickel cadmium battery 
pack. At the end of the battery pack's useful life, it must be recycled or 
disposed of properly. Contact your local, county, or state hazardous 
waste management authorities for information on recycling or disposal 
program in your area.
LIGHTNING
Your telephone has built-in lightning protection to reduce the risk of dam-
age from surges in telephone line and power line current. This lightning 
protection meets or exceeds FCC requirements. However, lightning strik-
ing the telephone or power lines can damage your telephone.
Lightning damage is not common. Nevertheless, if you live in an area that 
has severe electrical storms, we suggest that you unplug your phone dur-
ing storms to reduce the possibility of damage.
