Good morning, my ZK-MG arrived today and initially I am impressed.
The settings are confusing or the online manual I found are at least.
1st setting is duty cycle low, so that gets set to zero, next press is duty cycle high, so I set that to 80% (speed control)
Next press is frequency, well a lower frequency gives better control but with horrid noise so my compromise is 12K.
Then when you press again you get L00 then H80 which I assume is duty cycle again, then F12 then back to L00.
Is there a display brightness setting?
