3.2.1 Display
The Vibrex 2000 and Vibrex 2000 Plus use an LCD screen on
the front panel, for visual output. This screen subdivides into
eight lines of text.
CAUTION: In extreme temperatures, the display may turn
black (too hot), or blank (too cold). In hot climates, covering
the display from direct sunlight is generally sufficient to
prevent the screen from becoming unreadable. In cold weather
climates, it is advisable to keep the Vibrex unit in a warm
enough place (near or above freezing if possible) to ensure its
continued use.
