INITIAL TESTING:
❒Connect a suitable 12 volt supply to J1- either 12 VAC or 12 VDC ( positive tip).
❒Set the frequency range switch to LOW.
❒BEFORE turning on the power, please read the WARNING below (also on the back of the case)
WARNING
TO ELIMINATE ANY POSSIBLE RISK OF HEARING LOSS, AVOID NEARBY EXPOSURE TO THE “RAT BLASTER” SOUNDS. THIS UNIT CAN CAUSE PERMANENT HEARING DAMAGE.
❒Turn on the power. The LED should light and you should hear an annoying, high pitched whine. If so, your Rat Blaster is working and ready to chase away those nasty critters bothering you. You can change the frequency range to whatever you desire and place the Rat Blaster wherever it is needed. The unit is tested on low frequency because it is easier for the human ear to hear. If it is functioning on low, rest assured that it will function on medium and high frequency too!
❒If you are not able to hear the high frequency noise and you have a voltmeter,you can still check to be sure that your Rat Blaster is functioning. Set the meter to AC volts and with the meter leads across the speaker terminals you should see about 12 to 15 VRMS on a typical meter. Voltage readings will depend on the supply used, of course. If you are getting a reading of some kind even if it is not 12
If you hear no sound and get no voltmeter reading, it is time to consult the troubleshooting guide.
