You need to replace the battery

I'm having the same problem, too. However, the beeping continues and continues. Even when it stops, the light comes back on. Any other thoughts?

Blinded by the light

SOURCE: Uniden 5.8 GHz Digital cordless w 3 handsets interference background noise no matter where we are in the house or which handset we use

This is possibly caused by the internet connection.
Try new ADSL filter.
You need one each per device.

Here is the solution I found.
I also bought this equipment and also didn't find anything suitable in the internet, BUT a phonecall to the suplier EUROCOM brought the solution.
I called their service nr. 03-9029000 and got the English user manual as a PDF doc. by email.

You need to reset the main base unit. Unplug the power from the back of the base. While the power is disconnected, press and hold the delete key while reconnecting the power. Wait for a long beep tone. When the display shows 88 or P, press play button one time. If you have a phone without an answering machine, disconnect the power from the back of the base, press and hold find hs button while reconnecting power.
