I cannot get a dial tone.

First,, try all of the suggestions above.
Move the cordless handset closer to the telephone base. You might have moved out of range.
If the previous suggestions do not work, disconnect the telephone line cord from your telephone and connect the telephone line cord to another telephone. If there is no dial tone on that other telephone either, then
the telephone line cord may be defective: try installing a new telephone ne cord.
If changing the telephone line cord does not help, the wall jack (or the wiring to this wall jack) may be defective.
Try using a different wall jack in your home to connect your EELL5511110033//EL51203/EL51253/EL51303/EL51353/EL51403/EL51453/EL51503 telephone, or contact your telephone service provider (charges may apply).

I cannot dial out.

First,, try all the suggestions in the item I cannot get a dial tone above.
Make sure you have a dial tone before dialing. The cordless handset may take a second or two to find the telephone base and produce a dial tone. This is normal. Wait an extra second before dialing.
Check that all the telephones connected to the same telephone line are hung up.
Make sure to set the dial mode to the correct setting (pulse dialing or tone dialing) for the service in your area (see Battery installation and charging on pages 7-8).
Eliminate any background noise. Noise from a television, radio,, or other appliances may cause the telephone not to dial out properly. If you cannot eliminate the background noise, first try muting the cordless handset before dialing, or dialing from another room with less background noise.
If other telephones in your home are having the same problem, the problem is in your wiring or telephone service. Contact your telephone service provider (charges may apply).

My cordless handset isn’t performing normally.

Make sure the power cord is securely plugged into the telephone base. Plug the power adapter into a different, working electrical outlet not controlled by a wall switch.
Move the cordless handset closer to the telephone base. You might have moved out of range.

Relocate your telephone to a higher location. The telephone will likely have better reception when installed in a high area.
If the other telephones in your home are having the same problem, the problem is in your wiring or telephone service. Contact your telephone service provider (charges may apply).

I experience poor sound quality when using the speakerphone.

For increased sound quality while using the speakerphone, place the handset on a flat surface with the dial pad facing up.
When using a speakerphone, controlling background noise in your environment is essential. While you are listening to your party, press
MUTE/DELETE to temporarily turn your microphone off. When it is your turn to speak, remember to press MUTE/DELETE again to turn the microphone on.
Excessive background noise will cause a speakerphone to fade in and out. Try controlling the background noise by turning off any audio devices near the speakerphone.

If background noise cannot be controlled, you should terminate speakerphone operation and return to normal handset mode.

I hear other calls while using my telephone.

Disconnect the telephone base from the telephone wall jack, and plug in a different telephone. If you still hear other calls, the problem is probably in your wiring or telephone service. Call your telephone service provider (charges may apply).

If the problem only occurs in certain areas of your environment, you can conclude that there is nothing wrong with the telephone.
Do not install this telephone near a microwave oven or on the same electrical outlet. You may experience decreased performance while the microwave oven is operating.
If your telephone is plugged in with a modem or surge protector, plug the telephone (or modem/surge protector) into a different location. If this doesn’t solve the problem, relocate your telephone or modem farther apart from one another, or use a different surge protector.

Maintenance

Taking care of your telephone

Your cordless 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 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 electric 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 water. If the telephone base should fall into water, DO NOT RETRIEVE IT UNTIL YOU UNPLUG THE POWER CORD AND TELEPHONE LINE CORDS FROM THE WALL. Pull the telephone out by the unplugged cords.

Important safety information

Especially 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 handset by radio waves, so there is a possibility that your 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.
Electrical power: The telephone base of this cordless telephone must be connected to a working electrical outlet that is not controlled by a wall switch. Calls cannot be made from the handset if the telephone base is unplugged, switched off o,, or if the electrical power is interrupted.
Potential TV interference: Some cordless telephones operate at frequencies that may cause interference to TVs 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 will often reduce or eliminate the interference.
Rechargeable batteries: This product contains nickel-metal hydride rechargeable batteries. Exercise care in handling batteries in order not to create a short circuit with conductive 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: Safely dispose of these batteries. Do not burn or puncture. Like other batteries of this type, if burned or punctured, they could release caustic material,, which could cause injury.
The RBRC™ Seal means that the manufacturer is voluntarily participating in an industry program to collect and recycle nickel-metal hydride rechargeable batteries when taken out of service within the United States.
These batteries may be taken to a participating local retailer of replacement batteries or recycling center. Or you may call 1 (800) 8-BATTERY for locations accepting spent Ni-MH batteries.

Precautions for users of implanted cardiac pacemakers

Cardiac pacemakers (applies only to digital cordless telephones): Wireless Technology Research, LLC (WTR), an independent research entity, led a multidisciplinary evaluation of the interference 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.

ECO mode

Power-conserving technology reduces power consumption for optimal battery performance. The ECO mode activates automatically whenever the handset is synchronized with the telephone base.
