Sound level meter - Frequently Asked Questions

1. Turning the backlight on and off

The backlight switches between on and off each time you press the [LIGHT] panel switch. Note that immediately after turning on the power, the backlight will always start off, regardless of whether the panel condition memory function is enabled or disabled.

2. Adjusting the contrast of the display screen.

The display screen contrast can be freely adjusted. Turning the LCD contrast volume on the bottom of the device clockwise with the included adjustment screwdriver increases the contrast, while turning it counterclockwise decreases it. Once the contrast is set, the automatic contrast correction function maintains a constant density regardless of ambient temperature changes.

<Please note>
Do not forcefully turn or push the LCD contrast volume knob, as this may cause malfunction.
