## Questions & Answers

**Q: Does it come with a stand?**
A: No stand is included. Its round design is made for tabletop placement or adhesive mounting. It can stand upright on a steady surface, but for optimal stability, we recommend laying it flat or using the included adhesive tape.

**Q: How do I install it?**
A: For adhesive mounting: first, ensure the tape does not cover the sensor vents on the back. Then attach it to any smooth, clean surface. For non-permanent placement, simply set it on a shelf, desk, or next to your 3D printer.

**Q: Can it switch between Celsius and Fahrenheit?**
A: Yes. Simply press the small blue button on the back to instantly toggle the display between °C and °F.

**Q: Does it include a battery?**
A: Yes! It comes with 4 LR44 batteries — 2 pre-installed and 2 extras. Each set lasts up to 8 months, providing reliable long-term monitoring.

**Q: How do I get accurate readings?**
A: Avoid direct sunlight, heaters, or vents. Allow about 20 minutes after placement for readings to stabilize. For best results, place in a central, open spot inside your enclosed space.
