Mark

Symbol and Description

*1: Although RWZ4316 and RWZ3846 are different in part number, they have same service parts.

*2: The numbers in the remarks column correspond to the numbers on the " EXPLODED VIEWS ".

*3: Refer to " PCB PARTS LIST ", " 2. SCHEMATIC DIAGRAM" and " 3. PCB CONNECTION DIAGRAM".

NOTES :

÷ Parts marked by " NSP " are generally unavailable because they are not in our Master Spare Parts List.

÷ 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.

÷ When ordering resistors, first convert resistance values into code form as shown in the following examples.

Ex. 1

When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by

J = 5%, and K = 10%).

560

= 56 × 101= 561 ................................................... RD1/4PU 5 6 1 J

47k

= 47 × 10 3 = 473 .................................................. RD1/4PU 4 7 3 J

0.5

= R50 ...................................................................... RN2H Â 5 0 K

1

= 1R0 ......................................................................... RS1P 1 Â 0 K

Ex. 2

When there are 3 effective digits (such as in high precision metal film resistors).

5.62k

= 562 × 10 1 = 5621 ........................................... RN1/4PC 5 6 2 1 F

÷ Reference Nos. indicate the pages and Nos. in the service manual for the base model.
