CAUTION: FOR CONTINUED PROTECTION AGAINST RISK

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

 

 

 

 

 

 

 

 

 

 

 

 

OF FIRE, REPLACE ONLY WITH SAME TYPE 4A, 125V FUSE.

If Main Fuse (F601) is blown, check to see that all components in the power supply

 

 

 

 

 

 

 

 

 

 

 

 

ATTENTION: UTILISER UN FUSIBLE DE RECHANGE DE

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

MÊME TYPE DE 4A, 125V.

 

 

 

 

 

 

 

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.
