X-Ray Scanner Warning Tips

Β 

πŸ”Œ Charging Safely

  • Charge with a standard USB-C charger (5V output, 500mA or higher) β€” any modern phone charger works.
  • Avoid damaged, uncertified, or modified chargers to keep the battery healthy.

βœ… Before You Scan

  • Make sure both the scanner and the wall area are dry β€” wipe off any moisture with a cloth first.
  • Keep the unit away from water and direct sunlight.
  • Moved it between hot and cold environments (car β†’ house in winter)? Give it a few minutes to reach room temperature before scanning.

πŸ“‘ Watch Your Surroundings

  • Running microwaves or other devices that emit strong signals nearby can throw off readings β€” pause them while you scan.
  • Some materials naturally affect accuracy: strong magnetic/electromagnetic fields, damp walls, metal-rich building materials, foil-backed insulation, conductive wallpaper, carpets, or certain tiles. If readings seem off, try a different sensitivity level.

πŸ–οΈ Scanning Technique

  • Take off rings, watches, and metal jewelry from your scanning hand β€” metal near the sensor can cause false readings.
  • Glide the scanner evenly across the wall with steady pressure. Don't lift it mid-scan or press harder/softer as you go.
  • Keep the scanner in full contact with the wall the entire time.
  • Keep your fingers (and your other hand) off the wall area being scanned β€” your body conducts too.
  • Slow and steady wins: the slower you scan, the more accurate the reading.
πŸ’‘ Pro tip: 90% of "inaccurate" readings come from scanning too fast or wearing a metal watch. Fix those two and you're golden.
