Up to 300 data can be stored. Unnecessary data can be individually deleted (refer to Item
(1), “Display stored data”), but this individual deletion does not free up memory
occupied by deleted data. Therefore,
may be displayed even though less than
300 data are stored. In such a case, use the defrag function to consolidate data and free
up the space occupied by deleted data, thereby allowing up to 300 data to be stored.
While memory defrag is in progress, do NOT turn off the power. In addition, before
starting memory defrag check that there is enough battery life left to avoid battery
shutoff during memory defrag.
