At this point the GR281 is write protected by an internal inhibit function for Data Protection and the memory contents are retained by the lithium power source.Power down is very fast, this being essential for data integrity, taking a maximum of 15 µS (15 microseconds) to power down from 5 volts to 0 volts. This is much faster than system power failure conditions.
