TROUBLESHOOTING TIPS
PROBLEM: No sound out of any channel.
SOLUTION: Use a DMM to check the power supply voltage, do
you have a fresh battery? If everything is OK, check your
assembly, especially your parts orientation (D1?). Also check
your earphones for proper operation as well as your sound
source.
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: Sound is terrible or “motorboating”
SOLUTION: Check your power supply voltage or your battery.
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.
