Last week one customer reported that his RT3S happend a problem with the inverted screen, which was inverted by itself, during operation. You maybe ask why happened this problem? and how to solve this?
1. The inverted screen may because of some improper operation.
2.This can be update by a firmware.
After update this firmware, the inverted screen will come back to normal.
If you also meet the same problem, please email to firstname.lastname@example.org to get this firmware, but if there is no problem with your radio, please dont use this firmware.
