Note: Th e resistan ce value of R8524 was ch anged to 22o hm first and th en to 10o hm ag ain . and finally to 0ohm . 0ohm is the best and 10ohm is better, but 10ohm and 22ohm are also effec\ tive. Therefore, when 22 or 10 ohm Resistor is mounted at R8524, it is not necessary to replace it by 0ohm Resistor as long as the unit \ has no problem.
