Charging the Accessory Handset
Use only the Uniden
Connect the AC adapter to the DC IN 19V jack on the bottom of the charging cradle, and place the cord through the molded wiring channel. 
Place the handset in the charging cradle with the display facing forward.
Make sure that the charge LED illuminates when the handset is seated.
What if the charge LED doesn’t light up?
Check the AC adapter connection. 
Make sure you are not using an outlet that’s controlled by a wall switch.
Connect the AC adapter to a standard 120V AC wall outlet.
Charge your handset at least 25 hours before using your new handset for the first time.
