Cautions

<Cautions when replacing parts>
• Do not reuse removed parts. Always use new parts.
• Note that the negative side of tantalum condensers is readily damaged by heat.
• Except for chemical condensers and tantalum condensers, voltage is not displayed on condensers with a voltage
resistance of 50V or less.
• Resistors not marked are 1/16W chip resistors.
• KΩ = 1000Ω, MΩ = 1000KΩ
• B characteristics of variable resistors and semi-fixed resistors are not displayed.
