Wondering how to do a reset to factory defaults on your Nokta Makro Simplex+? Your Simplex+ will save all settings automatically once you turn your detector off and on again except for ground balance, threshold, frequency shift and LED flashlight on/off. To return your detector back to factory defaults perform the steps below:

1. Turn the detector on by pressing the power button.
2. Once the SIMPLEX+ logo appears on the screen, press and hold down the Settings and Pinpoint/Confirm button simultaneously until 3 short beeps are heard.

If you need to perform a hard reset on your Simplex+, simply press and hold the Down Arrow/On-Off for 6 approximately seconds.
