Display Contrast
The LCD’s (Liquid Crystal Display) contrast is set from the
factory to a standard level. However it is possible for the user to
adjust the contrast, if desired. The contrast control is internal to
the BTR-800 unit near the front panel. The cover must be
removed for access to this control. See Figure 35.
