I've been asked to box up a dutch driver board for someone. So while I had some time, I put the driver board on the bench this evening to measure the power and change the freq to what they wanted. It's wired up into a dummy load and using a stable 15v.

When switching it on, the board doesn't locked! The only way I've been able to get it to lock is having to press either the up button and then the down button or down button and then the up button.

Anyone got clue? They bought it sold as seen without any info. I've never used these boards before so bit of a loss.

It's the small blue driver with logo with a face giving the finger like the one attached but without the satcan.

This looks like an board made by RFhead, you should ask him

Thats a old version but i will PM you
