Made with all the same high quality components as our signature 20/100 second digital timer, we now offer a timer that looks identical but functions as a 20 second timer in both directions. We stand behind the quality of all of our timers and offer a repair service directly by the manufacturer for the 20 second timer too in the case of damage to the toggle switch.

  • Use a Phillips head #1 screwdriver for unscrewing and gentle re-tightening.
  • Unscrew the single screw completely. Remove the back half of the case.
  • Load your battery, replace back half, and re-screw. Do not over-tighten the screw.
  • Clipping the timer to your belt on the right hip will orient the toggle in a 20-sec.-Off- 100-sec. sequence.
  • Worn on the left hip, the forward-to-back sequence is reversed. Test the 20-second feature for battery power; the 12V should last 10 hours of beeping; the 91dB@30cm Piezo beeper sounds a clear tone.
  • This product is manufactured in California, U.S.A.
