The Handler Computer software monitors the air flow sensor on the laser fil-

ter system. If the sensor detects low air flow, the error message "Laser filter

full" is displayed. When this error message displays, the laser system will

mark 10 more devices as defined in the WinAH400.ini file.

WARNING: Failure to replace the laser vacuum filters at the

appropriate intervals could create a hazardous operating environ-

ment.

WARNING: This procedure should be performed only by quali-

fied service personnel who have successfully completed

Data I/O's laser training class. This procedure involves exposure

to hazardous by-products from the laser marking process.

WARNING: Electric shock hazard. Shut down the PS288 (see

“Shut Down the System” on page 3-12) and turn off the main

power switch.

WARNING: Hazardous materials. Wear safety goggles and dis-

posable protective gloves. Do not clean the laser vacuum filters by

blowing with compressed air, shaking, or using any method that

allows the particulate trapped by the filters to be released into the

work environment.
