Maintenance Notes
Cleaning of the Reader
It is recommended to clean the Reader on a regular basis. If you use the Reader
in a working area that is subject to dust or contamination, you should clean the
Reader more often. Use a dry cloth to clean the Reader. If the contamination is
persistent, you can also rub the surface of the Reader with a cloth that has been
moisturized with pure alcohol (isopropanol or ethanol). Do not use aggressive
cleaning agents such as acetone. If the inside of the Reader is contaminated,
please contact your supplier for technical assistance.
Service and repairs
For all service or repair needed beyond the change of battery, please contact your
supplier for assistance. Attempts to open or repair the Reader beyond the battery
port by any non-authorized personnel will void the warranty.
