Maintenance 

 

 

Warning 

Devices with malfunctioning lasers must be returned to the 
manufacturer for repair. 

Cleaning the Unit 

1.

 

Unplug the unit from the line power. 

2.

 

Clean the enclosure with a damp cloth. 

3.

 

Do not plug the unit back until it is completely dry. 

Cleaning the Connector Ends 

1.

 

Clean all connector ends with a lint-free tissue and alcohol before 
every mating.  See the “CLEANING CONNECTORS” section on page 
19. 

2.

 

Loosen the retaining screws of the connector panel, and remove the 
panel carefully to access the internal connectors (
