Wand Care
While there are no user-serviceable parts inside the wand, observing the following precautions will help ensure long term satisfactory
performance.
Do not use spray cleaner on the sensor or the wand. If you spray any liquid on the wand parts, damage may result.
1. Keep the electrical contacts of the wand interface module and calculator module ports free of obstructions. Should the contacts
become dirty, carefully brush or blow the dirt out of the contact area. do not use any liquid to clean the contacts.
2. Check the aperture in the wand tip periodically for dirt or obstructions. If it is necessary to clean the tip, first turn off the
HP-41C and remove the wand from the calculator. Then unscrew the tip from the wand body. The aperture can be cleared with
a cotton swab or similar device and a liquid detergent. The glass window on the sensor should be inspected and cleaned if dust,
dirt, or fingerprints are visible. To clean the sensor window, dampen a lint free cloth with liquid glass cleaner and clean the
window with the cloth.
