General Information on Cash Register Installation and Operation
4.1
Positioning the cash register
The cash register should be used in a location with normal room temperature and relative humidity. Do not expose the
cash register to extremely hot or cold temperatures, dusty conditions or direct sunlight.
4.2
Electrical
connections
Connect the cash register to a separate mains power outlet. Do not connect it to mains power outlets which also
accommodate a refrigerator, freezer or another electronic appliance which has a high power consumption. When
connecting the ECR to a computer, ensure the connections are correctly made. When connecting and disconnecting any
external units (BCR, PC, kitchen printer, etc.), disconnect the ECR from the mains power first.
4.3
Cleaning the cash register
Use a neutral cleaning agent to clean the outer surface. Never used agents containing oil or solvents such as acetone or
petroleum ether.
4.4
Changing the paper roll (57 mm, thermal) in the printer
4.4.1
Inserting a paper roll
Remove the printer cover. Pivot the paper transport unit up. Insert a thermal paper roll (57 mm in width and max. 70 mm
in diameter). Draw the leading edge of the paper over the tear-off edge and pivot the paper transport unit down, locking it
in place. Depending on the required use (bill or journal), either tear off the paper at the tear-off edge of the printer
mechanism or feed the paper onto the paper reel. Replace the printer cover.
