This video will show you how ti reconnect ADH300J headset with base.
If you can't see the solid green light on headphone, I presume probably headphone and base just need to re-connect.
①Disconnect the power of base.
②Turn OFF the Headphone Press ON / OFF control for 5 secondsuntil the Green LED flashes quickly.
③Connect the power of base immediately.
④Headphone and base will be connected automatically.
