Environment: Temperature, Humidity - Citizen BD2-2220 Specifications

Cautions
・Using the power supply other than specified, bad effect may occur in printing operation, etc.
・Using the current without removing peak current may result in degradation of printing quality
depending on the printing status or occurrence of low-voltage error.
・Use the power supply that can be turned off easily to prepare for emergencies.
・Power supply with overvoltage protection, overcurrent protection, and various protection
circuits is recommended.
・This control board requires two different supply voltages. Use sufficient care not to make
erroneous wiring or operation. Error in operation may not only break the control board but
also have bad effect on human body or peripheral equipment.
・Though this control board has CN2 that has the same pin allocation as BD2-2880, it is different
in supply voltage. Use sufficient care in handling this control board.
