S Important Points Concerning Numeral Memory Table Entries Used for
the Clock Function
Numeral memory table entries 247 through 253 store clock data, which is up-
dated by the internal clock of the NT30/30C. This data cannot be rewritten by
the PC.
Numeral memory table entries 247 through 253 are exclusively for display
(read only). Do not attempt to write data to them by using numeral settings or by
copying between memory table entries.
Do not allocate the numeral memory table entries to which the clock function is
assigned (numbers 247 to 255) to PC words.
This is the procedure for reading the time (hour, minute) set for the NT30/30C.
