3. Installing the Battery
Use a 9V alkaline battery for optimum performance (not included). Slide the cover of the battery compartment in the
direction of the arrow. Make sure the black ribbon is under the battery when you insert it and respect the polarity
indications on the inside of the battery compartment. Replace the cover.
The battery needs to be replaced when the device no longer functions properly and the message “LOW BAT” is
displayed on the LCD. We advise you to remove the battery in case of prolonged inactivity since a leaking battery
can destroy electronic parts.
4. Stabilising the Distance Measurer
The device is sensitive to changes in temperature and humidity. Wait ± 15 minutes and let the device reach room
temperature prior to use.
5. Activating/Deactivating the Device
