How to use speaker phone on cordless 5.8 GHz dual handset

SOURCE: base not able to connect to handset.

I successfully reset Radio Shack (Uniden) 5561 handset by reconnecting the battery while holding the '*' and '#' key, then press the right upper soft key near the LCD window. The display will indicate "EEPROM/RAM cleared!!" and will return the handset to the factory default condition - looking for a base to register to.

Unplug the battery. Hold down The * (star) and the #(hash) keys simultaneously. Re-connect the battery, phone will beep and screen will be blank. Press the voicemail (righthand silver key under the lcd screen). As above EEPROM/RAM message will appear. Place handset on base and your problem is solved.

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

It may not be registed with the main unit. You may need to register the handset. With my uniden all i have to do is put it in the main base until it says what handset it is (it should be a number).

If you have any questions please dont hesitate to ask

I had the same problem!

What you need to do is hold the "end" and "#" key for 5 sec, which will deregister the headset then all you would have to do is place it back in the base for it to registered again.
