HOW TO USE BASIC MODE OF ZAPPER (dont know how to troubleshoot)
1. for DURATION ZAPPING: turn device on by depressing red button until beep goes off. the diode "duration zap" should light up.
2. press yellow button for a second or 2 to activate. you should see "zap active" AND "duration zap" diodes blink alternately.
1. for ZAPPING WITH TIMED 7sec.on-20off-7on-20off: press red button only till you hear beep begin.
2. press yellow button to activate. "zap active" should blink.
IF THERE IS NO CURRENT FLOW (wrist straps not wet, wires not plugged in) THE DEVICE STARTS BEEPING CONTINUOUSLY.
Insert smart key if you have them before turning on unit. keys are not needed for regular zapping to work at default 30 kHz.
