Time Setting

■ Setting method

• Be aware that the time is progressing when you set the time.

• If no key is pressed over 60 sec, returning to RUN mode and not storing the setting value.

1. In the parameter setting, set the output operation mode.

2. In RUN mode, press [◀] key to enter the time setting mode.

3. The last digit flashes at the time setting display part.

4. Set the time.

[◀] key: shift the setting digit, [▲] key: shift the flashing position, increasing time

5. Press [MD] key to complete the setting and return to RUN mode.
