Hazardous Voltage
This equipment uses high voltage electricity which can SHOCK, BURN or
cause DEATH.
Always make sure the electrical power is turned off before attempting to
change a component or inspecting the inside of the equipment. A
residual charge may exist in capacitors, even with the equipment turned
off. Always short all supply lines to the chassis with an insulated
screwdriver or a similar tool before touching the circuit.
Working on the Scanner Unit Mast
Work on the scanner unit mast is dangerous, and doubly so if the proper
precautions are not taken.
1. Post an appropriate warning sign near the display unit to indicate that
work on the scanner unit is being performed, to prevent accidental
application of the power to the scanner unit.
2. Wear a safety helmet and always be aware of where the scanner
radiator is.
