Parts checklist

Your telephone package contains the following items. Save your sales receipt and original packaging in the event that warranty service is necessary.

Installation

You must install and charge the battery before using the telephone. See pages 10-11 for easy instructions.

Install the telephone base close to a telephone jack and a power outlet not controlled by a wall switch. The telephone base can be placed on a flat surface or vertically mounted on the wall (see page 14). For optimum range and better reception, place the telephone base in a central and open location.

If you subscribe to high-speed Internet service (DSL - digital subscriber line) through your telephone line, you must install a DSL filter between the telephone line cord and the telephone wall jack (see the following page). The filter prevents noise and caller ID problems caused by DSL interference. Please contact your DSL service provider for more information about DSL filters.

Your product may be shipped with protective stickers covering the handset and telephone base displays - remove them before use.

Troubleshooting

My telephone doesn’t work at all.

Make sure the power cord is securely plugged in.
Make sure you plug the battery connector securely into the cordless handset.
Make sure you plug the telephone line cord securely and firmly into the telephone base and the telephone wall jack.
Charge the battery in the cordless handset for at least 10 hours. For optimum daily performance, return the cordless handset to the charger when not in use.
If the battery is depleted, it may take approximately 30 minutes to charge the handset before it shows Low battery. See page 10 for details.
Reset the telephone base. Unplug the electrical power. Wait for approximately 15 seconds, then plug it back in. Allow up to one minute for the cordless handset and telephone base to reset.
You may need to purchase a new battery. Please refer to
Battery installation and charging are discussed in this user’s manual on pages 10-11.

The display shows no line. I cannot get a dial tone.

Try all the suggestions, as mentioned above.
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, your telephone line ord may be defective. Install a new telephone line 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 CL84107/CL84207/CL84257/CL84307/CL84327/CL84347/CL84357/CL84367 telephone, or contact your telephone service provider (charges may apply).

I cannot dial out.

Try all the suggestions, as mentioned 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.
Eliminate any background noise. Noise from a television, radio o, or other appliances may cause the phone to not 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 phones in your home are having the same problem, contact your telephone service provider (charges may apply).
Charge the battery in the cordless handset for at least 10 hours. For optimum daily performance, return the cordless handset to the charger when not in use.
You may have too many extension phones on your telephone line to allow all of them to ring simultaneously. Try unplugging some of the other phones.
The layout of your home or office may be limiting the operating range. Try moving the telephone base to another location, preferably to a higher location.
If other phones in your home are having the same problem, contact your telephone service provider (charges may apply).
Test a working phone at the phone jack. If another phone has the same problem, contact your telephone service provider (charges may apply).
Other electronic products can cause interference with your cordless phone. Try installing your phone as far away as possible from electronic devices such as television sets, VCRs, or other cordless telephones.
Remove the battery. Install the battery again and place the cordless handset in the charger. Wait for the cordless handset to reestablish its connection with the telephone base. Allow up to one minute for this to take place.
Your line cord may be defective. Try installing a new line cord.

My calls cut in and out while I’m using my cordless handset.

Other electronic products, such as HAM radios and other DECT phones, can cause interference with your cordless phone. Try installing your phone as far away as possible from these types of electronic devices.
Do not install this phone near a microwave oven or on the same electrical outlet. You may experience decreased performance while the microwave oven is operating.
If you plug your phone in with a modem or surge protector, plug the phone (or modem/surge protector) into a different location. If this does not solve the problem, relocate your phone or modem farther apart from one another, or use a different surge protector.
Move your telephone base to a higher location. The phone may have better reception when installed in a high area.
If other phones in your home are having the same problem, contact your telephone service provider (charges may apply).

The system does not respond to remote commands.

Make sure to enter your remote access code correctly (page 112).
Make sure you are calling from a touch-tone phone. When you dial a number, you should hear tones. If you hear clicks, the phone is not a touch-tone telephone and cannot activate the answering system.
The answering system may not detect the remote access code while your announcement is playing. Try waiting until the announcement is over before entering the code.
There may be interference on the phone line you are using. Press dialing keys firmly.

I subscribe to a nontraditional telephone service that uses my computer to establish connections, and my telephone doesn’t work.

Make sure your computer is powered on.
Make sure your Internet connection is working properly.
Make sure that the software is installed and running for your nontraditional telephone service.
Make sure to plug your USB telephone adapter into a dedicated USB port on your computer. Do not plug it into a multiple-port USB hub (USB splitter) that is not powered.
In a few rare instances, the USB port on your computer may not have enough power. Try using a USB hub with its own external power supply.
If you are using a firewall, it may prevent access to your nontraditional telephone service provider. Contact your service provider for more information.

A common cure for electronic equipment.
If the telephone does not seem to be responding normally, try putting the cordless handset in the charger. If it does not fix the problem, do the following (in the order listed):

Disconnect the power to the telephone base.
Disconnect the cordless handset battery.
Wait a few minutes.
Connect the power to the telephone base.
Remove the battery. Replace the battery and place the cordless handset into the charger.
Wait for the cordless handset to reestablish its connection with the telephone base. Allow up to one minute for this to take place.

Maintenance

Taking care of your telephone

Your cordless telephone contains sophisticated electronic parts, so you must treat it 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

You can damage your telephone 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.
