Chapter 1: Product and component descriptions
(11) Detector laser head ribbon connector: If this lead is broken or not connected, the detector
will indicate a HEAD Fault.
(12) Detector laser head assembly: No user-serviceable parts. Do not remove this from the
detector, due to the risk of exposure to the laser.
(13) Detector laser head cover plate: This protects the laser head. The plate should not be
removed from the detector.
(14) Replaceable dust filter: This simply slides in and out of its mounting. The separator and its
replacement have IN written in red on one side, and OUT on the other to indicate correct
orientation.
(15) Three mounting holes to mount the detector. Use #10-24 pan-head screws for mounting.
Note: Ensure that the detector is fixed to a flat surface so that the enclosure will not twist and
become damaged.
