Reference: Numeral memory table entries 247 to 255 are provided for clock data use and
host words cannot be allocated for them.
The following two methods can be used to set clock data for the NT31/NT31C
and NT631/NT631C. (With the NT21, the clock data is read from the host and
cannot be set at the PT.)
Setting from the System Menu
Display the menu for displaying and setting clock data from the System Menu
and make the settings. For details, refer to section 6 of the Setup Manual.
Rewriting Numeral Memory Table Entries 254 and 255
Numeral memory table entries 254 and 255 for clock data setting are rewritten
using the memory table copy function to set the clock data (it is not possible to
rewrite numeral memory table entries 254 and 255 from the host). For details,
refer to 3-10 Display and Setting of Calendar Clock (page 354).
