Advanced Features of the CL4940
Explore the AT&T CL4940’s advanced capabilities, including Caller ID, Call Waiting, and a fully-featured answering system for voicemail management and convenience.
Caller ID and Call Waiting
The AT&T CL4940 offers convenient Caller ID functionality, displaying the caller’s name and/or number on the handset’s screen before you answer. This allows you to screen calls and avoid unwanted interruptions. To utilize Caller ID, ensure you have subscribed to this service through your telephone provider.
Call Waiting alerts you to incoming calls while you are already on the phone. A distinctive beep will sound, indicating a new call is attempting to reach you. You can switch between calls seamlessly. Like Caller ID, Call Waiting requires a subscription from your service provider. Refer to your provider’s documentation for activation and usage details. The phone’s manual, available online at att.com, provides further clarification.
Remember to check compatibility with your phone service.
Answering System Setup and Usage
The AT&T CL4940 features a built-in answering system for capturing messages when you’re unavailable. Initial setup involves recording a greeting – a personalized message for callers. You can choose between a long greeting for general use and a short greeting for after-hours. Access the answering system settings through the phone’s menu.
To check for new messages, press the message access button. The system will announce the number of saved messages and play them sequentially. You can delete messages individually or all at once. Adjust recording volume and the number of rings before answering to customize the system to your preferences. Detailed instructions are available in the online user manual at telephones.att.com/manuals.
Ensure sufficient memory for message storage.
Voicemail Management
While the AT&T CL4940 has an answering system, it’s important to distinguish it from voicemail provided by your telephone service provider. This phone displays voicemail indicators, prompting you to access your carrier’s voicemail service. Accessing voicemail typically involves pressing and holding the message call button, or a designated key specified by your provider.
Voicemail management – checking messages, deleting, and saving – is handled entirely through your phone company’s system, not the CL4940 itself. Refer to your service provider’s documentation or website for specific voicemail instructions. The phone simply facilitates the connection; the online manual at telephones.att;com/manuals offers limited voicemail guidance.
Remember to set up a secure voicemail password.
Troubleshooting Common Issues
Resolve typical AT&T CL4940 problems like no dial tone or poor sound quality. Basic troubleshooting tips are available online and in the user manual.
No Dial Tone Troubleshooting
Experiencing no dial tone with your AT&T CL4940? Begin by verifying the phone cord is securely connected to both the phone and the wall jack. Ensure the phone jack is active – test with a known working phone.
Check for any physical damage to the phone cord. If using a phone line filter, confirm it’s properly installed. Disconnect all other devices connected to the same phone line to isolate the issue.
If the problem persists, try a different wall jack. Refer to the full user manual at www.telephones.att.com/manuals for detailed diagrams and further assistance. Sometimes, a simple reset can resolve connectivity problems.
Poor Sound Quality Solutions

If using a headset, confirm it’s properly connected and functioning. Eliminate potential interference by moving the phone away from other electronic devices. A weak signal from the phone company can also cause poor sound; contact your provider.
Consult the complete user manual at www.telephones.att.com/manuals for advanced troubleshooting steps and diagrams.
Answering System Not Recording
Is your AT&T CL4940 answering system failing to record messages? Verify the tape (if applicable) isn’t full. Check the recording volume settings within the answering system menu – ensure it’s not set too low. Confirm the microphone isn’t blocked or muted.
Ensure the phone line is securely connected, as a poor connection can disrupt recording functionality. Test with a different phone line if possible. Review the user manual for specific error codes related to recording issues.

Maintaining a clean AT&T CL4940 ensures optimal performance and longevity. Always disconnect the phone from the power outlet and telephone jack before cleaning. Use a soft, slightly damp cloth to gently wipe the exterior surfaces of the handset and base unit.

Battery Replacement (if applicable)
The AT&T CL4940 is primarily a corded phone, and may not utilize batteries for core functionality.

If your model includes a battery, it’s typically located within the base unit.
To replace it, first disconnect the power. Locate the battery compartment (refer to the full user manual for specific location details). Replace the old battery with a new one of the correct type – typically a standard AA or AAA battery. Ensure correct polarity (+ and -). Reconnect the power to restore functionality. Dispose of old batteries responsibly, following local regulations;
Factory Reset Procedures
Performing a factory reset on your AT&T CL4940 will restore the phone to its original settings, erasing personalized preferences like call logs and saved numbers.
