ATUNER AMP UNIT
Decimal points for resistor
and capacitor fixed values
are expressed as :
2.2 2R2
0.022 R022
←
←
The >mark found on some component parts indicates
the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of
identical designation.
Symbol indicates a resistor.
No differentiation is made between chip resistors and
discrete resistors.
NOTE :
Symbol indicates a capacitor.
No differentiation is made between chip capacitors and
discrete capacitors.
