1, make sure there is no big metal object around. 2, power on the detector. 3, then power off and keep pressing the power button for around 5 seconds. Do not release the power button until the light comes on again then take your finger off the button. 4, After approx 2 seconds there will be 2 beeps, this means the recalibration was completed successfully. However, if you hear If 5 beeps then recalibration failed. There is a video walkthrough of this process here https://www.youtube.com/watch?v=jjjlK-iEsjg If this does not work please contact your local Quest dealer or distributor. If you have no local dealer/distributor you can contact Quest directly on care@deteknix.com

Some of you may have noticed issues with the Quest Go app recently and we sincerely apologise for any inconvenience this may have caused.
