## Questions & Answers

**Q: Where do i find the pdf manual for this product?**
A: This site might help you out.   Otherwise I would be OK with copying mine and emailing it to You.      https://www.youtube.com/watch?v=v44lCcWfR0g           Ray in AZ

**Q: Does the rj45 tester test the 8 wires plus the screen?  i.e. all 9 conductors in stp cables?**
A: The RJ45 connection does not test the ground. However, if you touch metal components of each RJ45 connector on the cable to the metal rings around the 1/4" testers, then the ground should tone out if it's connected.

**Q: Will this test cables with different connectors on each end? for example, a trs to xlr adapter cable with 1/4" trs on one end and xlr on the other?**
A: Yes, you can test cables with two different type connectors at the same time.

**Q: Where (in what country) is this made?**
A: The OSP CT-04C is manufactured in China.
