Report a Hardware or Software Issue

If your Mnemo is not behaving as expected — whether it is a hardware failure, a firmware bug, or an unexpected behaviour during a survey — please fill in the failure report form and send it to us.

The report helps us identify patterns, improve the device, and assist you as quickly as possible.

What to report​

  • Device not powering on or off correctly
  • Screen issues (missing pixels, flickering, blank display)
  • Compass errors or calibration failures
  • Incorrect depth or distance readings
  • Firmware crashes or unexpected resets
  • Connectivity problems (Wi-Fi, USB)
  • Waterproofing concerns or physical damage
  • Any behaviour that differs from what the manual describes

How to submit​

  1. Open the report form using the button below
  2. Print it or save it as a PDF (Ctrl+P → Save as PDF)
  3. Fill it in — the more detail the better
  4. Send it to sebastien@arianesline.com or open an issue on GitHub

Tips for a useful report​

  • Note your firmware version before submitting (visible in the main menu)
  • Include the dive number and conditions when the issue occurred
  • Attach a photo or video if the failure is visible
  • If the device crashed, describe the exact sequence of button presses that led to it
