Notes;
1). The number of points actually available for use is determined by the hardware configuration.
2). The number of points can be increased by using an auxiliary timer.
3). Precision of calendar timer:
- At 0C/32 F, less than 119 seconds error per month.
- At 25C/77 F, less than 51 seconds error per month.
- At 55C/131 F, less than 148 seconds error per month.
4). The possible number of write times is 10,000 or less
When the optical battery is used, data of all area can be backed up. Areas to be held and not held can be specified using the system registers.
5). When setting to the holding area, since the holding area will not clear during power up when no battery is installed, the data may become irregular. If the battery runs out the data in the holding area will become irregular.
