Cleaning
Use care when cleaning the SEL-3031. Perform the following steps:
Step 1. Use a mild soap or detergent solution and a damp cloth to clean the
chassis.
Step 2. Be careful cleaning the front and rear panels because a permanent
plastic sheet covers each panel.
Do not use abrasive materials, polishing compounds, or harsh chemical solvents (such
as xylene or acetone) on any surface.
