Tip 1 of 5

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 5

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 3 of 5

Other electronic products (i.e., 802.11 wireless networking products, radios, radio towers, pager towers, cell phones, intercoms, room monitors, televisions, personal computers, kitchen appliances and other cordless phones) can cause interference with your cordless phone. Try installing your phone as far away as possible from these types of electronic devices.

Tip 5 of 5

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.
