11. Testing Slide power switch to “ON” position. The red LED should light and change brightness with according to signal strength. If the LED does not light, TURN OFF IMMEDIATELY and proceed to the next slide “Troubleshooting” Turn the volume control to a mid position and you should hear a hiss from the speaker. Test the unit with a CricketSat. You should hear a tone or clicking sound up to 1000 feet away.

12. Troubleshooting No sound or lights, no smoke –Try a new battery –Insure that slide switch is working properly –Check if battery leads correctly attached to board, red +, black - –Check if D1 diode is properly installed, white band - –Check if amplifier IC and RF receiver modules installed properly No sound, but lights –Turn volume control to a median setting. Should hear hissing sound Does not receive CricketSat tone or pulses –Receiver module may be faulty or need re-tuning
