SL9003Q Front Panel

4.2.1 LCD Display

The SL9003Q front panel LCD (Liquid Crystal Display) is the primary user interface and
provides status, control, configuration, and calibration functionality. Menu navigation and

screens are described in this section.

Contrast Adjustment

: The contrast adjustment is front panel accessible (to the left of the

LCD). Use a small flathead screwdriver to adjust for optimum visual clarity.

4.2.2 Cursor and Screen Control Buttons

The buttons on the SL9003Q front panel are used for LCD screen interface and control

functions:
