Therapeutic systems of 1 MeV or more shall be designed so that:
- (1) irradiation cannot be possible until a selection of a number of dose monitor units has been made at the control panel;
- (2) the pre-selected number of dose monitor units are displayed on the treatment control panel until reset manually for the next irradiation;
- (3) after irradiation is terminated, the dosimeter display must be reset to zero before subsequent treatment can be initiated; and
- (4) for post-1989 systems, after termination of irradiation, the preselected dose monitor units must be manually reset before irradiation can be initiated.
