Remarks
The automatic backlight off will be remained active after this function is called. Duration of the automatic
backlight off can be set at the control panel. For example, if the automatic backlight off is set to “disable mode”
at the control panel, the function cannot be activated.
During an event of low battery, the backlight still can be turned on. However, because of inrush current at
a time of turning on the backlight, the power of PA-2400W may be turned off. Always observe the battery
condition before activation of the backlight.
