2.4 Cover
The standard cover provides environmental
protection and fits over the top, front and sides
of the main chassis. The front panel has viewing
windows for the LCD, LEDs and sensor cartridge
fitted in the sensor cartridge chamber. Underneath
the LCD window are the 4 push buttons used for
navigating the detector's software menus. The cover
is easily removed to allow access to the chassis by
unscrewing the thumbscrew on the front panel and
pulling the cover forwards off the main chassis.
Midas units fitted with a pyrolyzer utilize a ventilated
cover due to the high temperatures generated by
the pyrolyzer unit (See Diagram 2-7)
