Depending on the GP's Environment and Brightness settings, sometimes the
screen's display will seem to flicker. This may be because the brightness has
been set to low, or that the GP's surrounding environment has become either
too hot or too cold, however, this problem does not usually occur. In order to
correct this problem, please use the following setting.
• This setting is only available on the GP577RS unit.
REFRESH RATE
Use the four display samples on the left side to gauge whether the "+" or "-"
adjustments help to correct the problem. While the normal setting value is
"0", there are two levels available in the minus direction (from "0") and 18
levels available in the "+" direction (from "0").
