3. Connect Telephone Lines: Connect your telephone line cords to the LINE 1, LINE 2, LINE 3, and LINE 4 jacks on the back of the phone base. Connect the other ends to your wall telephone jacks.
4. DSL Filter (if applicable): If you have DSL internet service on the same line as your phone, you may need to use a DSL filter (not included) to prevent interference. Connect the DSL filter between the wall jack and the phone line cord.
5. Install Backup Batteries: The phone requires 1 Product Specific battery (included). Install it in the designated compartment. For power outages, using rechargeable 9V backup batteries (not included) is recommended.
6. Initial Configuration: Upon first power-up, the phone may prompt you to set the date, time, and assign an extension number for the unit within your system (e.g., 11, 12, etc.). Refer to the "Operating" section for details on setting these parameters.

Proper care ensures the longevity of your AT&T 1040 phone system.

• Environmental Conditions: Avoid exposing the phone to extreme temperatures, direct sunlight, or excessive moisture.

Troubleshooting

If you encounter issues with your AT&T 1040 phone, try the following solutions:

• No Dial Tone / Unresponsive Dialing:
  • Ensure all phone cords and the power adapter are securely connected.
  • If using DSL, verify that a DSL filter is properly installed.
  • Perform a hard reset: Disconnect the power adapter and all phone lines, remove any backup batteries, wait for a few minutes, then reconnect everything.
• Speakerphone Not Working:
  • Check the volume settings using the VOLUME buttons.
  • Ensure the MUTE function is not active.
  • A hard reset (as described above) may resolve this issue.
• Intercom Issues (Screeching, Unintelligible Audio):
  • Interference can cause these issues. Ensure cell phones or other electronic devices are not placed directly next to the phone.
  • Try configuring non-adjacent extension numbers for your stations (e.g., 12, 16, 20, 24 instead of 11, 12, 13, 14) to potentially reduce frequency interference.
  • Ensure the power adapter is plugged directly into a wall outlet, not a power strip, as some power strips can introduce noise.
• Caller ID Not Displaying (on 1040 model):
  • The AT&T 1040 model does not inherently support Caller ID. This feature is available on models like the AT&T 1070.

If problems persist after attempting these solutions, consult the full user manual (link provided in "What's in the Box") or contact AT&T customer support.
