Installation

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 (page 6). The filter prevents noise and caller ID problems caused by DSL interference. Please get in touch with your DSL service provider for more information about DSL filters. Your product may be shipped with a protective sticker covering the telephone base display – remove it before use.

CAUTION: To reduce the risk of fire or injury to persons or damage to the telephone, read and follow these instructions carefully:

  • Use only alkaline AA batteries (not included).
  • 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.
  • Do not open or mutilate the battery. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.
  • Exercise care in handling batteries in order not to create a short circuit. Do not allow conductive materials such as rings, bracelets, or keys to touch the battery. The battery or conductor may overheat and cause harm.
  • Use the battery identified for use with this product only by the instructions and limitations specified in this manual.
  • Observe proper polarity orientation between the battery and metallic contacts.
  • Do not disassemble your telephone. There are no serviceable parts inside. Refer to qualified service personnel for servicing.
  • To prevent the fire or battery explosion risk, replace with the correct battery type. Dispose of used batteries according to the instructions.

Battery installation

Before using the telephone, you should install four new AA alkaline batteries (not included) to provide memory backup and enable the use of some features. The four AA batteries are required for the following features to work: speakerphone, caller ID, display, menu, directory, redial, speed dial, clock, Audio Assist®, and the INCOMING CALL light.

If you unplug the telephone line cord from the telephone wall jack when there are no working batteries installed, the following information will be lost: caller ID history, directory entries, speed dial entries, and all settings in the feature menu. We recommend you install new batteries before initial use and change the batteries soon after the low battery icon appears.

 CAUTION: Always unplug the telephone line cord before installing new batteries.

  1. Press the large tabs on the battery compartment cover, as the arrows indicated below, to open the battery compartment cover.ATT CL2940 Corded Phone with Speakerphone User Manual-fig 8

About caller ID

This product supports caller ID services offered by most telephone service providers. Caller ID allows you to see the name, number, date, and time of calls. The available caller ID information will appear after the first or second ring.

Information about caller ID with call waiting

Caller ID with call waiting lets you see the name and telephone number of the caller before answering the call, even while on another call.

It may be necessary to change your telephone service to use this feature. Contact your telephone service provider if:

  • You have both caller ID and call waiting, but as separate services (you may need to combine these services).
  • You have only caller ID service, or only call waiting service.
  • You don’t subscribe to caller ID or call waiting services.

There are fees for caller ID services. In addition, services may not be available in all areas.

This product can provide information only if both you and the caller are in areas offering caller ID service and if both telephone service providers use compatible equipment. The time and date, along with the call information, are from the telephone service provider. Caller ID information may not be available for every incoming call. Callers may intentionally block their names and/or telephone numbers.

NOTE: You can use this product with regular caller ID service, or you can use this product’s other features without subscribing to caller ID or combining caller ID with call waiting service.

Caller ID history

How the caller ID history (caller ID log) works
The telephone stores caller ID information about the last 65 incoming calls. Entries are stored in reverse chronological order. The phone deletes the oldest entry when the log is full to make room for new calls. If you answer a call before the information appears on the screen, it does not show in the caller  ID history. Caller ID entries are listed in reverse chronological order. If there are consecutive incoming calls from the same caller ID number, the caller ID history only shows the last call information from that number.

Missed (new) call indicator

  • When the telephone is in idle mode and has new or missed calls, its screen shows XX MISSED CALLS.
  • When you press CALL LOG to review the caller history, the missed call indicator will be cleared. If you do not want to review the missed calls one by one but still want to keep them in the caller ID history, you can press and hold CANCEL to clear the indicator when the telephone is in idle mode.
  • The NEW icon in each missed call entry will not be cleared until you review it. The missed call indicator will display and resume counting again after receiving a new missed call.

Memory match

If the incoming telephone number matches the last seven digits of a telephone number in your directory, the name that appears on the screen matches the corresponding name in your directory.

For example, if Christine Smith calls, her name appears as CHRIS if this is how you entered it into your directory.

 NOTE: The number shown in the caller ID log will be in the format sent by the telephone service provider. The telephone service provider usually delivers 10-digit phone numbers (area code plus telephone number). If the telephone number of the caller does not match a number in your directory, the name will appear as it is delivered by the telephone service provider.

Reasons for missing caller ID information

Troubleshooting

If you have difficulty with your telephone, please try the following suggestions. For customer service, or to purchase accessories or replacement parts, visit our website at www.telephones.att.com or call 1 (800) 222-3111. In Canada, dial 1 (866) 288-4268.

My telephone does not work at all.

  • Unplug the batteries and telephone line cord. Wait for approximately 15 seconds, then plug them in again. Allow up to one minute for the telephone to synchronize.

There is no dial tone.

  • Try the suggestion mentioned above.
  • The telephone line cord may be defective. Try installing a new telephone line cord.
  • Make sure the coiled handset cord is securely installed between the handset and the telephone base.
  • Disconnect the telephone base from the telephone jack and connect a different telephone. If there is no dial tone on that telephone either, the problem is in your wiring or telephone service. Contact your telephone service provider (charges may apply).

I cannot dial out.

  • Try all the suggestions mentioned above.
  • Make sure there is a dial tone before dialing. It is normal for the telephone to take a second or two before producing a dial tone. 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 (touch-tone dialing or pulse dialing) for the service in your area (see Dial mode on page 12).
  • If any of your other telephones are having the same problem, the problem is in the wiring or telephone service. Contact your telephone service provider (charges may apply).
  • If you are using the speakerphone, eliminate any background noise. Noise from a television, radio, or other appliances might cause the telephone to not dial out properly. If you cannot eliminate the background noise, first try muting the telephone before dialing, or dialing from another room in your home with less background noise.

The telephone does not ring when there is an incoming call.

  • Make sure the ringer is on (see page 16).
  • Make sure the telephone line cord is plugged in properly (see Telephone installation on page 6).
  • There may be too many extension telephones on the telephone line to allow all of them to ring simultaneously. Try unplugging one telephone at a time until the telephones start ringing.
  • Test a working telephone at the same telephone jack. If another telephone has the same problem, the problem is in the telephone jack. Contact your telephone service provider (charges may apply).
  • The telephone line cord may be defective. Try installing a new telephone line cord.

My calls fade out or cut in and out when I am using the telephone.

  • If you are using the handset when this problem occurs, try unplugging the coiled handset cord and firmly plugging it into the handset and telephone base again.
  • If you are using the speakerphone when this problem occurs, eliminate any background noise. Noise from the television, radio, or other appliances may cause the speakerphone to cut in and out. Try pressing MUTE when you are not speaking to eliminate the background noise.
  • Disconnect the telephone base from the telephone wall jack and plug in another corded telephone. If calls are still not clear, the problem is probably in the wiring or telephone service. Contact your telephone service provider (charges may apply).
  • 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 Telephone installation on page 6). The filter prevents noise and caller ID problems caused by DSL interference. Please get in touch with your DSL service provider for more information about DSL filters.

I hear other calls when using the telephone.

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

Operation during a power failure.

  • This telephone operates during a power failure if a telephone line cord is plugged between the telephone wall jack and the telephone base. You can answer calls with the handset and make calls using the dialing keys. No other features work unless batteries are installed. All settings in the menu options are retained during a power failure if a telephone line cord is plugged between the telephone wall jack and the telephone base.
  • If you neither install batteries nor a telephone line, after a few minutes, the telephone clears the directory, caller ID history, speed dial memory, and the last number dialed memory. At the same time, all settings in the menu options change back to their default settings.

My caller ID features are not working properly.

  • Caller ID is a subscription service. You must subscribe to this service from your telephone service provider for this feature to work on your telephone.
  • The caller may not be calling from an area that supports caller ID.
  • Both your and the caller’s telephone service providers must use equipment compatible with caller ID service.
  • 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 Telephone installation on page 6). The filter prevents noise and caller ID problems caused by DSL interference. Please get in touch with your DSL service provider for more information about DSL filters.
  • Make sure the area codes are set correctly (see Home area code on page 13 and Local area code on page 14).
  • Reset the telephone. See Common Cure for Electronic Equipment on page 41.

The telephone does not receive caller ID or the telephone does not display caller ID during call waiting.

  • Make sure you subscribe to caller ID with call waiting features provided by the telephone service provider.
  • The caller might not be calling from an area that supports caller ID.
  • Both your and the caller’s telephone service providers must use equipment compatible with caller ID service.

I’ve set my LCD language to Spanish or French and I don’t know how to change it back to English.

  • When the telephone is in idle mode, press MENU/SELECT once, then enter *3645474#.

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 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. In these instances, try using a USB hub with its 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.

Common cure for electronic equipment:
If the telephone is not responding normally, try resetting the telephone. Do the following in the order listed:

  1. Disconnect the telephone line cord from the telephone base.
  2. Remove the batteries.
  3. Wait a few minutes before connecting the telephone line cord to the telephone base.
  4. Place the batteries back.
  5. Wait for the telephone to synchronize its connection. This might take up to one minute.
