Ramsey Electronics PPM3 manual

known good cables between the stereo, line level source, and PPM3. Try switching cables or using a different cable if you’re having audio trouble.

PROBLEM: The microphone doesn’t work.

SOLUTION: Test the microphone with another unit to be sure it works on its own. Make sure it’s plugged solidly into the jack on the PPM3 and be sure that the “Mic Mute” button is pressed.

PROBLEM: One or more of my LEDs are not lighting.

SOLUTION: First of all, check to be sure you’ve got the LEDs installed correctly. Each LED has a flat side that corresponds to the negative or cathode lead of the part. Read back in the assembly instructions and make sure that the flat side and negative lead are placed correctly. If the power-on LED is not working make sure you have a good input voltage source and that it is plugged securely into the power jack on the PPM3. Ok, it seems simple but make sure the power switch is pressed. If the “Mic Mute” LED is not lit, check to be sure that that switch is pressed. The same goes for the “Clip” LED; you must have the “Phone Mute” button pushed and there must be enough audio level to cause the “Clip” LED to light.

PROBLEM: I just can’t make the &#^$^@! thing work!
