5. Sensor Handling Tips
5.1 Battery lid
To open and close the battery lid, gently push the back side label close to the battery lid with your thumb
and slide the battery lid downwards with your other hand.
5.2 Sensor element
The sensor elements must be handled with care as these are sensitive parts.
5.3 Battery insertion
The battery powered sensors operate with 4 batteries, note the polarity when inserting the batteries.
Polarity is always shown in the sensors battery compartment as well as on the battery itself.
It is very important to follow the battery requirements when inserting batteries, see page 16.
Verify that the front panel LED is turned on within 5 seconds after inserting batteries. Note that it may
only be turned on for a very short while to save battery. If you do not see the LED come on even for a
short while, please remove the batteries and re-insert them again. If it still doesn’t work, please see the
Troubleshooting section.
5.4 External power input
For sensor requiring an external power supply, insert the USB-C connector on the bottom side of the
sensor carefully until a “click” is detected. See each product manual for more details.
Verify that the front panel LED is turned on within 5 seconds after inserting power.
