SECTION 4 DIAGRAMS THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) For Printed Wiring Boards. Note: • Y: Parts extracted from the conductor side. • : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (SIDE B) Parts face side: (SIDE A) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated. • MAIN board is muliti-layer printed board. However, the patterns of intermediate-layers have not been included in diagrams. • Lead layouts surface For Schematic Diagrams. Note: • All capacitors are in μF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums. • All resistors are in Ω and 1/4 W or less unless otherwise specified. • C : Panel designation. • A : B+ Line.

Therefore, the schematic diagram excerpts and has described only a part. Replace a part according to "METHOD OF JUDGING RIGHT AND WRONG OF PARTS RELATED TO SWITCH" (page 7) in servicing notes. Exchange the entire mounted board when parts that do not correspond to it are defective. Note 2: When the MAIN board is replaced, there are some notes. Refer to "NOTE THE MAIN BOARD REPLACING" (page 4) in servicing notes for notes. NWZ-X1050/X1051/X1060/X1061 27 27
