Sensor LEDs

Sensors have 2 LEDs that indicate their status: Health LED and Mode LED. See images 1 & 2.

These LEDs do not appear on the sensors unless you press a magnetic tag (see image 3) on the bottom left-corner of the device for 3 seconds.

The Checkit tag is a magnet which could interfere with heart pacemakers and implantable cardioverter-defibrillators (ICDs).

See the images below to locate the LEDs and tag press position on Sealed Sensors and Sensor+ PUBs .
