DISPLAY CONTRAST
The gauge display may be difficult to read when viewed in bright
light. If so, adjust the display contrast as follows:
✓
Loosen the four captive screws located in the corners of the
keypad.
✓
Gently lift the control unit from the gauge and tilt it forward.
✓
As shown in Figure C–1, an adjustment potentiometer for the
display contrast is located inside an access hole in the back
panel of the control unit.
✓
Using a small screwdriver, adjust the potentiometer to obtain
the desired display contrast.
✓
Gently place the control unit inside the gauge and tighten the
four captive screws in the corners of the keypad.
