Troubleshooting - Ramsey Electronics STC1 Instruction Manual

TROUBLESHOOTING TIPS
PROBLEM: No 1.5MHz oscillator signal.
SOLUTION: First check your testing procedures to make sure your scope is on
the correct settings and that you have the power on the STC-1. If so, check the
collector of Q1 for 6MHz. If you do not have signal there, check surrounding
parts for shorts or cold solder joints. Otherwise, check U6 for power on it's pins,.
PROBLEM: One channel is out, the other works OK.
SOLUTION: You may have a short or open somewhere through the circuit.
This is where an oscilloscope would come in handy. Insert an audio signal into
both of the inputs, then trace through the circuit with the probe. When you have
gazinda (input) with no gazada (output), you will then know where the problem
lies.
PROBLEM:
The sound is distorted before the LEDs light.
SOLUTION: Back down the settings on the clip level adjusters. High frequency
sounds aren't registered as quickly on the indicators as is low frequencies. The
LEDs should almost never light on the proper settings.
PROBLEM: Any one of the LEDs never lights, even when turning the clip adjust
all the way up.
SOLUTION: Check the orientation of the installed LED to make sure it was
installed in the correct direction. Try reversing it and see if it lights.
PROBLEM: I just can't get the #@%*$#&! thing to work! It's Ramsey's fault!
SOLUTION: Read the warranty information towards the back of this manual.
