This is a mechanical error that occurred during the production of the first series.
Because the downtime was very long, the manufacturer was not able to make the conversion. If I could recommend it, you might want to add some helpful information to your merchant kit. Anyone who has received the new product will not be able to handle the problem with confidence. There is always an exception. So if the redesign is not workable, then it is advisable to include help information along with the shipment, what is the solution to repairing the malfunction.
This is just a suggestion - I just suggest the opportunity.
- If only the USB connector does not fit in place:
/g/nanovna-users/message/10333- If the login screen freezes or there is no menu screen when turned on:
/g/nanovna-users/message/10369 and
/g/nanovna-users/message/10498 may be the solution.
