PCMtuner common problem and solution:

1. Problem: Cannot connect to computer. There is no response when connecting to computer.

Solution: The reason is that the power supply of pcmtuner is divided into USB communication power supply and PCB host power supply. Many users often plug USB into the system separately and no PCB power supply leads to no reaction of the device.

2.Problem: Sometimes PCMTuner software prompts the device cannot be found when identifying and reading data.

Solution: In this case, just plug and unplug the adapter power supply.

3. Problem: PCMTuner software shows not active.

Solution: After you register, just wait for 24 hours, and the factory will activate for you automatically. No need to offer an email to the seller to activate now.
If over 24 hours, still not activated, can ask your seller to check for you.
NOTE: if you change the computer to install, still need to ask YOUR SELLER to re-activate for you
Remember one tool, one email, one computer!

7. Problem: Will the device burn if use another power supply, not PCMTuner?

Solution: Don't use your power supply, or it will burn triode easily.

If you use your own lab power and voltage regulator.
You don't know how device power works.
Just adjust the voltage to 13.5 or whatever you think will cause the whole triode to burn out.
