Can't turn the ringer on. the light says "ringer

The procedure varies from phone to phone. Since you neglected to specify the model of your Uniden DECT 6.0 phone I can only suggest you select it from the list beginning here to download a copy of the manual.

Google at&t 2.4 ghz cordless phone manual and checkout the links.

Ringer On/Off and Ringer Volume 1. Make sure your phone is in idle mode. (not in Talk mode) 2. Press the VOL (- or +) button to activate the ringer volume setting. 3. Press either the LINE 1 or LINE 2 Soft key to select the desired line. 4. The LCD will display the volume range and currently-selected volume in an ascending series of bars. 5. Press the VOL (- or +) button up or down to increase or decrease the volume in steps. 6.The system will retain the last entry, it is not necessary to save or acknowledge your selection from this mode.
It is also possible you have set the DND (Do Not Disturb) feature which will also caution your phone not to ring when a call comes in.
Have a great day. Hope this helps.

Hold down the pound key (#) until it goes away.

Please give me positive feedback if this helps you.

Thanks.

Assuming that this is a digital phone with a Navigator button (like 76xx or DTxxx), then press either the RING OFF soft key and the up button on the navigator button, or just keep pressing the up button on the navigator and the RING OFF will change to a level and the phone will ring.

Without the exact model it is difficult to find the manual.

Here the manual for 900 series/996:Uniden EZI996.

I also quote from manual:
