Warning:
• When the light source chamber cover shall be opened, be
sure to turn OFF the power switch and disconnect the power
cable from power supply.
• It is very dangerous to touch the lamp by any mistake
because high voltage, approx. 30kV, is applied to the + pole
of the xenon lamp when the lamp is lit on and 20V is applied
while the lamp is lit.
• The xenon lamp is still charged just after the power switch is
turned OFF. Leave more than 5 minutes after the power
switch is turned OFF before open the light source chamber
cover to avoid electric shocks.
• It is very high temperature right after the Xenon lamp is
turned OFF. Wait until it is cooled down sufficiently for
replacement. The time required for cooling down the lamp is
an hour when it is left with its power supply turned OFF,
while it is 30 minutes when the lamp is turned OFF with
"LAMP" of the AUX FUNC set at "0".
