The training mode is used when the operator or the manager practices register operations.
When a training cashier has been selected, the machine automatically enters the training mode. When a
training cashier has not been selected, the register automatically enters the ordinary REG mode. (For
programming of a training cashier, please consult your local dealer.)
The training operations are valid only in REG, MGR, and VOID mode.
The training cashier memory is updated in the training mode. Other memories are not updated.
