## Questions & Answers

**Q: Can I restart the machine immediately after a 10 minute work cycle?**
A: Yes, you can. The automotive smoke machine is set to work for 10 minutes by default, but it can actually work for quite a long time.

**Q: What are the advantages of variable frequency operation technology?**
A: The technology does not stop the smoke tester due to temperature, as it keeps the machine temperature within reasonable limits at all times. This allows our smoke leak detectors to work longer and have a longer service life!

**Q: Are smoke machines for cars easy to use?**
A: Yes, smoke machines for cars are relatively easy to use. Simply connect the machine to the car's gas intake system, turn it on, and watch for smoke to appear.
