INSTRUCTIONS AND USE 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.
