Parameter Setting

• Some parameters are activated / deactivated depending on the model or setting of
other parameters. Refer to the description of each parameter.
• If any key is not entered for 60 sec in each parameter, it returns to RUN mode.
• After returning to RUN mode, press the [MODE] key within 2 sec, it returns to
previous parameter.
• [MODE] key: Saves current setting value and moves to the next parameter.
[◀] key: Checks fixed value / Changes setting digits.
[▲], [▼] key: Changes setting values.
