Basic operation

HORIBA

●

Using the backlight

When it is difficult to see the screen in a dark location, you can turn on the backlight by
pressing the

key. If the backlight is not operated for 5 minutes, it automatically turns

off. To turn it off manually, press the

key again while the backlight is on.

Note

・

Turning on the backlight consumes energy and shortens battery life.

・

The backlight becomes unavailable when the battery level becomes low.
