attempt to service the equipment.

Maintenance is limited to the following periodical checks:

Examine the cables for signs of damage, such as chafing, nicks and 
cuts.

•

Check that the cable connectors are firmly attached.

•

Remove the scanner cover and check for signs of water damage.

•

Make sure the scanner is still securely attached to the mounting 
surface.

•

Once a year, remove, grease and re-attach the mounting bolts securing 
the scanner.
