9.1.2. Power ON/OFF

Power is turned on when the power switch is pressed.

To turn off the power, hold down the power switch for 0.5 second or more.

Note

The power switch is a soft-switch, so the internal microcomputer is still operating even when the power switch is set to OFF.

9.1.3. Changing the input parameters

Step 1. Press the Input channel selection key to choose the input channel for which you want to change the volume from those with the illuminated Input channel ON/OFF indicator (channel number).

The selected channel's selection indicator (red dot) lights, and the channel name and volume level are displayed on the VFD screen.

Step 2. Adjust the input parameters.

Adjust the volume, bass, treble, or other input parameters. (Refer to p. 40 "Input setting items.")
