Introduction

If you are unable to hear anything during hands free calling, the internal speaker may need to be replaced. This guide will teach you how to disassemble your AT&T CL4940 corded answering system, and how to replace the speaker used for hands free calling. This is a fairly simple process, and it can be accomplished with minimal technical expertise.

    • Starting from the bottom of the device, (using a metal spudger) separate the top (white) plastic piece from the bottom (gray) plastic piece.

    • Work your way across the bottom of the device, then to each side, and finally to the top.

    • There are brackets every few inches along the edge of the device. These may be difficult to pull apart.

    • The top and bottom pieces should separate, and the internals of the device will now be accessible.

    • Using wire cutters, sever both the red and the black wires connected to the microphone.

    • To remove the microphone from the device, gently wiggle it while pulling it apart.

Conclusion

To reassemble your device, follow these instructions in reverse order.

I'd rather install a new microphone instead of just reinstalling the old one.

Is there a link to where a new microphone can be purchased?
