STANDARD
To turn on the nGauge 4x4 Temperature Sensor, unscrew the top and locate the power button. Press and hold this button for at least 5 seconds and wait 1 minute before trying again if needed. You should start receiving updates in the app. Screw the lid back on tightly. The sensor is waterproof, however complete submersion should be avoided.
