When using your telephone equipment, basic safety precautions should always be followed to reduce the risk of fire, electric shock and
injury, including the following:
1. This product should be installed by a qualified technician.
2. This product should only be connected to the host equipment and never directly to the network such as Public Switch Telephone
Network (PSTN) or Plain Old Telephone Services (POTS).
3. Read and understand all instructions.
4. Follow all warnings and instructions marked on the product.
5. Unplug this product from the wall outlet before cleaning. Do not use liquid or aerosol cleaners. Use a damp cloth for cleaning.
6. Do not use this product near water such as near a bath tub, wash bowl, kitchen sink, laundry tub or swimming pool, or in a wet
basement or shower.
7. Do not place this product on an unstable table, shelf, stand or other unstable surfaces.
8. Slots and openings in the back or bottom of the telephone base and handset are provided for ventilation. To protect them from
overheating, these openings must not be blocked by placing the product on a soft surface such as a bed, sofa or rug. This product
should never be placed near or over a radiator or heat register. This product should not be placed in any area where proper
ventilation is not provided.
9. 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 on the premises, consult your dealer or local power company.
10. Do not allow anything to rest on the power cord. Do not install this product where the cord may be walked on.
11. Never push objects of any kind into this product through the slots in the telephone base or handset because they may touch
dangerous voltage points or create a short circuit. Never spill liquid of any kind on the product.
12. To reduce the risk of electric shock, do not disassemble this product, but take it to an authorized service facility. Opening or
removing parts of the telephone base or handset other than specified access doors may expose you to dangerous voltages or other
risks. Incorrect reassembling can cause electric shock when the product is subsequently used.
13. Do not overload wall outlets and extension cords.
14. Unplug this product from the wall outlet and refer servicing to an authorized service facility under the following conditions:
A. When the power supply cord or plug is damaged or frayed.
B. If liquid has been spilled onto 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 operation instructions. Improper adjustment of other controls may result in damage and often requires extensive work by an
authorized technician to restore the product to normal operation.
E. If the product has been dropped and the telephone base and/or handset has been damaged.
F. If the product exhibits a distinct change in performance.
15. Avoid using a telephone (other than cordless) during an electrical storm. There is a remote risk of electric shock from lightning.
16. Do not use the telephone to report a gas leak in the vicinity of the leak. Under certain circumstances, a spark may be created when
the adapter is plugged into the power outlet, or when the handset is replaced in its cradle. This is a common event associated with
the closing of any electrical circuit. The user should not plug the phone into a power outlet, and should not put a charged handset
into the cradle, if the phone is located in an environment containing concentrations of flammable or flame-supporting gases, unless
there is adequate ventilation. A spark in such an environment could create a fire or explosion. Such environments might include:
medical use of oxygen without adequate ventilation; industrial gases (cleaning solvents; gasoline vapors; etc.); a leak of natural gas;
etc.
17. Only put the handset of your telephone next to your ear when it is in normal talk mode.
18. The power adapters are intended to be correctly oriented in a vertical or floor mount position. The prongs are not designed to hold
the plug in place if it is plugged into a ceiling, under-the-table or cabinet outlet.
19. Use only the power cord and batteries indicated in this manual. Do not dispose of batteries in a fire. They may explode. Check with
local codes for possible special disposal instructions.
20. In wall mounting position, make sure to mount the telephone base on the wall by aligning the eyelets with the mounting studs of
the wall plate. Then slide the telephone base down on both mounting studs until it locks into place. Refer to the full instructions in

between portable wireless telephones and implanted cardiac pacemakers. Supported by the U.S. Food and Drug Administration, WTR
recommends to physicians that:
Pacemaker patients
• Should keep wireless telephones at least six inches from the pacemaker.
• Should NOT place wireless telephones directly over the pacemaker, such as in a breast pocket, when it is turned ON.
• Should use the wireless telephone at the ear opposite the pacemaker.
WTR’s evaluation did not identify any risk to bystanders with pacemakers from other persons using wireless telephones.
Operating range
The cordless telephone operates with the maximum power allowed by the Federal Communications Commission (FCC). Even so, the
cordless handset and telephone base can communicate over only a certain distance - which can vary with the locations of the telephone
base, cordless handset, the weather, and the layout of the hotel.
When the cordless handset is out of range while on a call, the cordless handset rapidly beeps three times.
If there is a call while the handset is out of range, it may not ring, or if it does ring, the call may not connect well when you answer the call.
Move closer to the telephone base to answer the call.
If the handset moves out of range during a telephone conversation, there may be interference.
To improve reception, move closer to the telephone base.
About cordless telephones
• Privacy: The same features that make a cordless telephone convenient create some limitations. Telephone calls are transmitted
between the telephone base and the cordless handset by radio waves, so there is a possibility that the cordless telephone
conversations could be intercepted by radio receiving equipment within range of the cordless handset. For this reason, you should not
think of cordless telephone conversations as being as private as those on corded telephones.
• Network wall jack: The telephone base of the cordless telephone must be connected to a working network wall jack with
Power over Ethernet (PoE). Calls cannot be made from the cordless handset if the telephone base is unplugged or switched off.
• Potential TV interference: Some cordless telephones operate at frequencies that may cause interference to televisions and VCRs. To
minimize or prevent such interference, do not place the telephone base of the cordless telephone near or on top of a TV or VCR.
If interference is experienced, moving the cordless telephone farther away from the TV or VCR often reduces or eliminates the
interference.
• Rechargeable batteries: Exercise care in handling batteries in order not to create a short circuit with conducting material such as rings,
bracelets and keys. The battery or conductor may overheat and cause harm. Observe proper polarity between the battery and the
battery charger.
• Nickel-metal hydride rechargeable batteries: Dispose of these batteries in a safe manner. Do not burn or puncture the battery. Like
other batteries of this type, if burned or punctured, they could release caustic material which could cause injury.
The RBRC®seal
The RBRC®seal on the nickel-metal battery indicates that VTech Communications, Inc. is voluntarily participating in
an industry program to collect and recycle these batteries at the end of their useful lives, when taken out of service
within the United States and Canada.
The RBRC®program provides a convenient alternative to placing used nickel-metal batteries into the trash or
municipal waste, which may be illegal in your area.
VTech’s participation in RBRC®makes it easy for you to drop off the spent battery at local retailers participating in the
RBRC®program or at authorized VTech product service centers. Please call 1 (800) 8 BATTERYTM for information on
Ni-MH battery recycling and disposal bans/restrictions in your area. VTech’s involvement in this program is part of
its commitment to protecting our environment and conserving natural resources.

Maintenance
Taking care of your telephone
Your telephone contains sophisticated electronic parts, so it must be treated with care.
Avoid rough treatment
Place the handset down gently. Save the original packing materials to protect your telephone if you ever need to ship it.
Avoid water
Your telephone can be damaged if it gets wet. Do not use the handset outdoors in the rain, or handle it with wet hands. Do not install the
telephone base near a sink, bathtub or shower.
Electrical storms
Electrical storms can sometimes cause power surges harmful to electronic equipment. For your own safety, take caution when using
electrical appliances during storms.
Cleaning your telephone
Your telephone has a durable plastic casing that should retain its luster for many years. Clean it only with a soft cloth slightly dampened
with water or mild soap. Do not use excess water or cleaning solvents of any kind.
Remember that electrical appliances can cause serious injury if used when you are wet or standing in the water. If the telephone
base should fall into the water, DO NOT RETRIEVE IT UNTIL YOU UNPLUG THE NETWORK CABLE FROM THE WALL. Then remove the
telephone by the unplugged cords.
