Battery Charge Level Warning - Citizen CMP-20 Technical Manual

CMP-30 product specification document

7. Battery charge level warning

The printers power is supplied by the internal batteries. If the battery charge level is not high and power intensive
printing is performed, such as graphics with large black sections, problems may occur due to the lithium ion
battery's characteristics, such as voltage dropping and stopping printing.
When performing high load printing it is recommended that you take care to maintain a high charge level on the
battery LEDs.
