Adjusting the brightness of the display panels and indicators
In a dark environment
If the displays and indicators are hard to see because of low lighting conditions, move the LIGHT switch on the front panel to the ON position to switch on the backlighting.
In a bright environment
If the indicators in the operating buttons are hard to see because the lighting is too bright, set the LIGHT switch to the BRT position. This increases the intensity of the indicators.
Unless lighting conditions require either of these settings, leave the LIGHT switch in the OFF position.
