*1. When the optional battery is installed, general type devices can be changed to latched (battery
backed) type devices by the parameter setting. However, the latched range cannot be set.
*2. For applicable functions, refer to Chapter 37.
For handling of the latched area, refer to Section 2.6.
*3. Supported in Ver.1.10 or later.
