10-39: The first digit indicates the pollution degree of the using place
and the second digit indicates the accumulated operating time of
IDU. The two digits are described as follows:
Slight pollution: The first digit is "1". If the second digit is "0", it
indicates that the accumulated operating time is 5500 hours. The
accumulated operating time is added by 500 hours when the second
digit is increased by "1”. When the second digit is “9”, the
accumulated operating time is 10000 hours.
Medium pollution: The first digit is "2". If the second digit is "0", it
indicates that the accumulated operating time is 1400 hours. The
accumulated operating time is added by 400 hours when the second
digit is increased by "1". When the second digit is "9", the
accumulated operating time is 5000 hours.
