less are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise specifi ed.
All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ
Indication of resistance, which does not have one for rating
electrical power, is as follows:

Divided schematic diagram:
Some schematic diagrams are divided into several pieces.
Information to where the line is to be connected is printed at the end
of each line.
