When the screen where the buzzer attribute has been set is displayed during the
operation of the NT31/NT31C, the buzzer sounds automatically according to the
setting. For the procedure for changing the screen, refer to 8-3-1 "Switching the
Screen" (page 480).
This method allows the operator to sound the buzzer at any required time.
