2.6 Cleaning
The unit may be cleaned by wiping with a soft cloth. The front panel and display / keypad may be wiped with a
slightly damp soft cloth containing soapy solution or a mild detergent. Do not use any lemon based (citric acid)
product to clean the display / keypad.
2.7 Contrast Adjust (Monochrome Only)
The contrast or viewing angle of the monochrome LCD display can be adjusted from the side panel. If not
adjusted correctly, the display may look dim, dirty, completely black, washed out or blank. Insert a small star or
Phillip type screwdriver into the hole in the side panel as shown in Figure 2-12 and turn to adjust the display
contrast. The adjustment potentiometer has a 270° rotation. Do not apply excess pressure or attempt to
turn it beyond the end stops.
