5.6 INITIALIZE INTERNAL MEMORY
• The GP's internal clock has a slight error. At normal operating tempera-
tures 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.
• When writing the clock data in the System Data Area, input Year, Month,
Date, Hour and Minute, like setting the clock data in the OFFLINE mode.
