- If the S215 door station shows a blank blue screen or gets fully frozen, and no buttons respond at all, please provide the S215 firmware version and a video recording of the fault to DNAKE Technical Support Team.
- Follow the remote guidance from DNAKE technical staff to perform USB flashing.
- If the S215 still fails to work normally after USB flashing, please export and submit the device log for further analysis.
- After log inspection, if the issue is confirmed to be caused by poor connection of the screen cable, disassemble the device and re-plug the screen connector cables properly.
- Please break it open and put the parts back as indicated in the three pictures in turn, and then try turning the device on.
- If the problem is diagnosed as a defective screen or other hardware failure:
- For devices within the warranty period: Contact the DNAKE sale engineer to initiate the RMA process.
- For devices out of warranty: Customer needs to bear the relevant shipping and maintenance fees. Please consult DNAKE sale engineer for detailed arrangements.
