Remark

NOTE:

• Due to standardization, replacements in

the parts list may be different from the
parts specified in the diagrams or the
components used on the set.

• -XX and -X mean standardized parts, so

they may have some difference from the
original one.

• RESISTORS

All resistors are in ohms.
METAL:Metal-film resistor.
METAL OXIDE: Metal oxide-film resistor.
F:nonflammable

• Items marked “*” are not stocked since

they are seldom required for routine service.
Some delay should be anticipated
when ordering these items.

• SEMICONDUCTORS

In each case, u : µ, for example:
uA.. : µA..

uPA.. : µPA..

uPB.. : µPB.. uPC.. : µPC..  uPD.. : µPD..

• CAPACITORS

uF :  µF

• COILS

uH :  µH

The components identified by
mark 

!

 or dotted line with mark.

!

 are critical for safety.

Replace only with part number
specified.

Les composants identifiés par une
marque 

!

 sont critiques pour

la sécurité.
Ne les remplacer que par une piéce
portant le numéro spécifié.

When indicating parts by reference
number, please include the board.
