Hi Rakwireless professional users
My new RAK10701 field tester has problem, RAK10701 field tester screen is always black,
(1) I have tried to turn on device by pressing power button, for many times, screen is still black
(2) connect to PC toolbox, wistoolbox can read tester’s information,
Hi Bernd,
Thank you,
open the case, there is battery around the soft cables,
I think I need to remove battery first, then I can check the cable connection,
