User Manual for Victor 1212-3A Printing Calculator

Quick guide from the manual

The Victor 1212-3A is a 12-digit printing calculator. It can be powered by an AC adapter or four AA batteries. Important: Do not press any keys when the printer is on and there is no paper loaded, as this can damage the print head. Always ensure the paper holder is in position and paper is loaded before operating the printer.

Device description
