Tip 1 of 11

Confirm proper installation of the telephone base power supply, handset chargers (where applicable) and handset battery(s). You should only use the AT&T power supply(s) provided with your telephone. Confirm that the electrical outlet to which the power supply is plugged is working. Additionally, make sure the power supply is not connected to an electrical outlet that is controlled by a wall switch.

 

Tip 2 of 11

Ensure the telephone cord is securely installed at the base and the wall jack. Or try another telephone cord.

 

Tip 3 of 11

When placing the handset in the base or charger, confirm that the charge contacts are making a good connection. The charging battery icon is displayed and, on selected models, the CHARGE light illuminates on the handset while it charges.

You should allow 16 hours to fully charge the handset battery. For optimum daily performance, return the handset to its telephone base or charger when not in use.

 

Tip 4 of 11

Move the handset closer to the base. The operating range may vary with environmental conditions and time of use. There may be places within your environment that a cordless phone will not work well. If the problem only occurs in certain areas of your environment, you can conclude that there is nothing wrong with the phone. Consider trying a phone that operates on a different wireless frequency.

 

Tip 5 of 11

Make sure your handset is registered to the base unit. Refer to the Adding and registering handsets procedure in the User’s Manual.

 

Tip 6 of 11

If you have connected this telephone to a phone jack that has not been used before, or that has not been used in sometime, there may be problems with this jack that you are not aware of. Use a telephone jack that you know is in proper working order.

 

Tip 7 of 11

If the other phones in your home are having the issue, the problem could be related to the telephone wiring in your home, or with your local telephone service. Please call your service provider for further assistance.

 

Tip 8 of 11

Ensure that your cordless handset is cradled properly. Proper cradling will be confirmed by the CHARGE light remaining on.

 

Tip 9 of 11

Tip 10 of 11

Complete the following steps to reset the telephone system:
Step 1: Disconnect the power to the telephone base.

Step 2: Disconnect the handset batteries.

Step 3: Wait a few minutes and then reconnect the power to the telephone base.

Step 4: Reconnect the handset batteries.

Step 5: Wait about one minute for the handsets to re-establish a link with the telephone base and then test the phone again.

NOTE: After resetting the telephone system, you will need to reset the clock. [On models with answering systems]: If the time is not set, you will hear Time and Day Not Set when you listen to messages.

NOTE: If you have caller ID service, the time will automatically be updated whenever caller ID information is delivered. However, since caller ID delivers the date, rather than the day, you must program the year once so the system can derive the day of the week.

To set the day and time, complete the following steps:

Step 1: Using the handset, when the phone is not in use, press MENU/SELECT.

Step 2: Press ▲DIR or ▼CID until you see Set date/time. Next, press MENU/SELECT.

Step 3: Press ▲DIR or ▼CID to select the month, then press MENU/SELECT; or use the dial pad to enter the month.

Step 4: Press ▲DIR or ▼CID to select the date, then press MENU/SELECT; or use the dial pad to enter the date.

Step 5: Press ▲DIR or ▼CID to select the year, or use the dial pad to enter the year; then press MENU/SELECT.

Step 6: Press ▲DIR or ▼CID to select the hour, then press MENU/SELECT; or use the dial pad to enter the hour.

Step 7: Press ▲DIR or ▼CID to select the minute, then press MENU/SELECT; or use the dial pad to enter the minute.

Step 8: Press ▲DIR or ▼CID to select AM or PM.

Step 9: Press MENU/SELECT. You will hear a confirmation beep.

Step 10: Press and hold OFF to return to the idle screen.

 

Tip 11 of 11

You may need to replace the handset batteries, especially if they have been in service for more than one year. To find replacements, refer to our AT&T Battery Finder. If batteries for your model are unavailable, you can search the internet using the key words cordless phone batteries for an on-line supplier. If you prefer to purchase locally, you can look for replacement batteries at your area consumer electronics retailers. It is recommended that you take your present battery with you to insure the replacements are the correct size and have the correct specifications.
