also automatically turn off after 10 minutes of non-use.

Operating Tips
• Use only D WALT 12V Max* lithium-ion battery.
E
• Ensure the D WALT battery is in good working condition. If the
E
battery fuel gauge on the screen is empty, the battery needs to be
recharged.
Avoid sudden changes in temperature such as when entering or
leaving a heated building on a cold day as this can cause condensation
inside the imaging thermometer. To prevent condensation, place the
imaging thermometer in the kitbox or a plastic bag before exposing it
to sudden changes in temperature.
