AT&T CL2909WH is a feature-rich cordless phone designed for convenience and ease of use. With its speakerphone capability, you can enjoy hands-free conversations, while the adjustable display contrast ensures optimal visibility. The Caller ID feature lets you identify incoming calls before answering, and the backlit keypad illuminates for clear visibility in low-light conditions. The phone also has a mute button to prevent background noise from interrupting your calls.

Troubleshooting:

Cannot hear or be heard via Speakerphone:

1. Your speakerphone will only allow sound to travel in one direction at a time. It can either

receive or transmit; it cannot do both at once. Background noise can cause the unit to seem like

it is cutting in and out, when really it is switching modes any transient noise like a subtle cough

or a fan in the background can cause the unit to switch modes. If you are using a speakerphone

where there is background noise, please use the MUTE button when you are not speaking. This

will prevent the unit from switching modes when you are not speaking.

2. If your telephone is not functioning properly, you may need to reset it:

Step 1. Disconnect the line cord from the base.

Step 2. Remove batteries

Step 3. Wait at least one minute. Plug in the line cord and reconnect the power.

LED not working; Display blank or faded:

1. You can adjust the display contrast.

Step 1: Press OPTIONS until SET CONTRAST is displayed.

Step 2: Press CALL LIST to raise or lower the screen contrast. There are four (4) contrast levels.

2. Ensure that the batteries are fresh and correctly installed in the base.

3. If your telephone is not functioning properly, you may need to reset it:

Step 1. Disconnect the line cord from the base.

Step 2. Remove batteries

Step 3. Wait at least one minute. Plug in the line cord and reconnect the power.

Handset falls to the ground, does not stay on when wall mounted:

The handset tab on the base of the phone must be reversed. Remove the handset from the

base (off-hook). Press down the switch hook, and slide the handset tab up and out of its slot.

Turn the tab so the end with the hook is up. Then, insert the handset tab back into its slot.

Caller ID not appearing; Caller ID incorrect data:

1. If you have other phones in your home with the Caller ID feature and none of them are

working, please Call Local Telco to report problem. Can request line be checked for noise or

trouble with Caller ID service. Note: Charges may apply.

Step 1. Disconnect the line cord from the base.

Step 2. Remove batteries

Step 3. Wait at least one minute. Plug in the line cord and reconnect the power.

3. There should not be any equipment between the jack and the Caller ID phone. This includes

faxes, adapters, answering systems, etc. Having equipment in between the jack and the phone

can cause the Caller ID information to be lost before it reaches the phone. Please plug the unit

directly into the phone jack.

4. If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY

phone jack that has a phone. The DSL signal can cause static/noise, squealing (similar to fax

tones), caller ID disruption and other issues on your line.
