CAUTION !

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.

If Main Fuse (F1001) is blown , check to see that all components in the power supply

circuit are not defective before you connect the AC plug to the AC power supply.

Otherwise it may cause some components in the power supply circuit to fail.  

NOTE:

The voltage for parts in hot circuit is measured using

hot GND as a common terminal.

"Ce symbole reprèsente un fusible à fusion rapide."

CAUTION !

For continued protection against fire hazard,

replace only with the same type fuse.

ATTENTION : Pour une protection continue les risqes

d'Incele n'utiliser que des fusible de m

ê

me type.

Risk of fire

-replace fuse as marked.

"This symbol means fast operating fuse."
