In places where dust or dirt has accumulated on the optical
surface, clean the surface with a small, soft-bristle brush.

Wash the surfaces thoroughly with water and a mild non-abrasive
detergent.
4
Thoroughly rinse the glass surface with clean water, ensuring no
residue is left behind.

Perform a functional check (see Functional Check , page 60).
7.2.2 Signal Verification
The signal verification check determines the proper operation of the open
path. It checks the alignment and cleanliness of the window or any problem
in the source or detector. Use the PC host software to measure the signal
verification.
Refer to Manual TM 799060 or use the I.S. handheld unit. Refer to Manual
TM 777070 for Non I.S. Mini Laptop Unit.
7.2.3 Functional Check of Unit
The SafEye Xenon has been calibrated at the factory per the user’s specific
gas or vapor detection requirements. This procedure validates the functional
operation. The functional check must be done periodically. Refer to
Functional Check , page 60 for instructions.
Caution : Disable automatic activation and disconnect any external device
that should not be activated during the calibration check.
