BECAUSE A HOT CHASSIS GROUND IS PRESENT IN THE POWER
SUPPLY CIRCUIT, AN ISOLATION TRANSFORMER MUST BE USED.
ALSO, IN ORDER TO HAVE THE ABILITY TO INCREASE THE INPUT
SLOWLY, WHEN TROUBLESHOOTING THIS TYPE POWER SUPPLY
CIRCUIT, A VARIABLE ISOLATION TRANSFORMER IS REQUIRED.
NOTE :
The voltage for parts in hot circuit is measured
using hot GND as a common terminal.
CAUTION:
FOR CONTINUED PROTECTION AGAINST RISK
OF FIRE, REPLACE ONLY WITH SAME TYPE 4A, 125V FUSE.
ATTENTION:
UTILISER UN FUSIBLE DE RECHANGE DE
MÊME TYPE DE 4A, 125V.

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.
