Special Notes
• The terminal contains High-Voltage and is extremely
dangerous. Disconnect any power cords when working
on the inside of the terminal with the cover removed.
• Be careful of the CRT face. The slightest crack in the
face could cause an implosion, therefore, causing an
injury. Always work with the neck of the unit facing you.
• When wearing the grounding strap do not connect it to
the terminal directly
• Remember to remove your grounding strap at anytime
when the terminal is to be powered on.
• The Anode lead may still contain a build-up charge after
the power has been removed so avoid touching it until
you are able to discharge it with the removal procedure.
