Assembling the Device
The WF-20 needs to be used with Dino-Lite AF series. The assemble
procedure is as described below.
Charge the WF-20 by connecting to a computer or a USB charger
using the Mini USB charging cable.
1. Pressing the two interface release buttons at the same
time to remove the USB interface adapter cap.
Remove the rubber lid from the WF-20. Suggest to cover
the rubber lid onto the USB adapter cap for preventing
dust build-up inside.
2.
Attach the WF-20 onto AF series with the Dino-Lite logos
facing the same side.
3.
Do not bend the join part anytime especially when
releasing the USB adapter cap or WF-20. Doing so may
cause damage on the devices.
