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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic product and exceptional customer support *by on Reviewed in the United States 15 August 2022* Accurate. Easy to use. Built like a tank. However, like others reported, the first time I fired it up the tester was intermittent due to the battery tray being loose. Rather than returning it, I emailed Elite Core. An hour later I received a reply -- from the CEO -- on a Sunday night. He replied, "Try pushing the battery sled all the way in and then push it downward while pushing inward at the same time. See if it clicks into place. We have had good luck with this technique. If it doesn’t work for you, let me know and I’ll send you another one!" I tried this simple technique AND IT WORKED. The battery sled clicked and locked into place. That is incredible customer service! I'm now an Elite Core customer for life. Highly recommended. ### ⭐⭐⭐⭐⭐ Awesome *by on Reviewed in Saudi Arabia 5 May 2021* Nice product. ### ⭐⭐⭐⭐ Es un buen producto. *by on Reviewed in Mexico 5 June 2022* Lo que no me gusta es que la caja que sostiene la batería se sale con facilidad al manipularlo.
