1-5. Units description
The detector consists of the following units.
1.
Push the two buttons at the top of the main unit together to
open the front cover. (Pushing only either one button cannot
open the cover, but then pushing the other can open it.)
* The front cover opens about 90 degrees at first. You can
push it down to 180 degrees.
2.
Hold the convexed parts on both sides of the sensor unit and
pull it out.
If the sensor unit is hard to detach, insert a finger into the gap
at the top right of the sensor unit and pull it out.
3.
When attaching the sensor unit to the main unit, thrust it onto
the main unit and make sure that the sensor unit is securely
fixed, otherwise it might come off.
4.
After replacing the sensor unit, close the front cover. Be sure
to check the click of the front cover to fix it properly, otherwise
it might open again.
CAUTION
• Each unit consists of precision parts. When a unit is detached, be careful not to drop it. Dropping the
unit compromises its original performance or causes malfunctions.
