INSTRUCTIONS FOR SERVICE PERSONNELBEFORE RETURNING APPLIANCE TO THE CUSTOMER, MAKE LEAKAGE-CURRENT OR RESISTANCE MEASUREMENTS TO DETERMINE THAT EXPOSEDPARTS ARE ACCEPTABLY INSULATED FROM THE SUPPLY CIRCUIT.

NOTES:1. Resistor values are in ohms (k=kilo-ohms, M=megohms).2. Capacitor values are in microfarads (p=picofarads).3. £Parts marked with this sign are safety critical components.

They must always be replaced with identical components-refer to the appropriate parts list and ensure exact replacement.

注意1. 抵抗の単位はΩ（ｋ＝ｋΩ，Ｍ＝ＭΩ）です。2. コンデンサの単位はμＦ（ｐ＝ｐＦ）です。3. £マークのある部品は安全規格重要部品です。交換するときは必ずティアック指定の部品を使用してください。
