Power Supply Block Diagram

FL10.3BLP

CAUTION !

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

If Main Fuse (F601) 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.  

For continued protection against risk of fire, 

replace only with same type  4 A, 125V fuse.

CAUTION ! :

ATTENTION :
