8. TEACH BUTTON
The Teach button located on the upper part of the sensor allows you to reboot the device in Recovery
mode. This function is needed to update the firmware of the sensor.
To enable the recovery procedure, boot the device whilst holding the TEACH button down until the
output LEDs (the two central ones) start to flash; this means the sensor is loading its recovery software.
Using the software supplied with the update kit, it is then possible to connect the sensor to the PC and
enable the update procedure. Please refer to the manual supplied with the Kit for further details.
