application memory capacity for screen data by 1 MB.
Clock
± 65 seconds per month (deviation at room temperature and power is OFF).
Variations in operating conditions and battery life can cause clock deviations from -
380 to +90 seconds per month.
For systems where this level of precision is insufficient, the user should monitor and
make adjustments when required.
