CONFIRMATION OF CHECK SUM, POWER ON TOTAL HOURS AND MICON VERSION
Initial total of MEMORY IC, POWER ON total hours and MICON VERSIONcan be checked on the screen. Total hours are
displayed in 16 system of notation.
NOTE: If you set a factory initialization, the total hours is reset to "0".
Please refer to "CONFIRMATION OF INITIAL DATA" when SUM DATA is not corresponding.
1. Turn on the POWER, and set to the ALL mode.

1. Turn on the POWER, and set to the ALL mode.
2. Set the VOLUME to minimum.
3. Press both VOL. DOWN button on the set and Channel button
(6)
on the remote control for more than 2 seconds.
ADDRESS and DATA should appear as FIG 2.

8. Repeat steps 4 to 6 until all data has been checked.
9. When satisfied correct DATA has been entered, turn POWER off (return to STANDBY MODE) to finish DATA input.
After the data input, set to the initializing of shipping.
10. Turn on the Power.
11. Set the VOLUME to minimum.
12. Press both VOL. DOWN button on the set and Channel button
(1)
on the remote control for more than 2 seconds.
