• The GP's internal clock has a slight error. At normal operating temperatures and
conditions, with the GP operating from its lithium battery, the degree of error is 65
seconds per month. Variations in operating conditions and battery life can cause
this error to vary from +90 to -380 seconds per month. For systems where this
degree of error will be a problem, the user should be sure to monitor this error and
make adjustments when required.
• To input the correct time into the System Data Area's time settings, use the GP's
OFFLINE mode. (Date information can be entered as well)
