About your accessory
With the Wireless Charger DT-904, you can charge the battery of your phone without

You need a USB charger with at least 1.5A output.

Gadgets 4.1 or later, and Bluetooth 4.0 or later. NFC works with Lumia phones supporting
NFC.

outlet, or to a suitable USB power source.
2. Make sure the charging plate is facing up and there's nothing on the plate.
3. Place your phone on the charging plate. The indicator light is on while the phone charges,
and fades out when the battery is full.
It's normal for the charging plate and phone to get warm while charging. If there’s a problem
