8.1 Self Test Error Code Display
The detector automatically performs a self-test after power on. If red indi-
cator are showed on the display window, it is probable that the sensor is
blocked by banknotes or dust. Please, use a brush or a piece of soft cloth
to clean the dust on the sensor or remove the banknotes, and then restart
the machine.

Whether the main power supply is within specified range (AC 100V
