Do not allow liquid to pool. #### Approved Cleaning Agents **Isopropyl alcohol** **Ammonium chloride** **Bleach: Sodium hypochlorite** **Hydrogen peroxide** **Mild dish soap** #### Cleaning Instructions **Cleaning Housing** * Using the alcohol wipes, wipe the housing including keys and in-between keys. **Cleaning Display** * The display can be wiped down with the alcohol wipes, but care should be taken not to allow any pooling of liquid around the edges of the display. Immediately dry the display with a soft, non-abrasive cloth to prevent streaking. (Not applicable to RFD8500 and RFD2000) **Cleaning Exit Window** * Wipe the scanner exit window periodically with a lens tissue or other material suitable for cleaning optical material such as eyeglasses. **Cleaning Cradle Connectors** * Remove the DC power cable from the cradle. * Dip the cotton portion of the cotton-tipped applicator in isopropyl alcohol. * Rub the cotton portion of the cotton-tipped applicator along the pins of the connector. Slowly move the applicator back and forth from one side of the connector to the other. Do not leave any cotton residue on the connector. * All sides of the connector should also be rubbed with the cotton-tipped applicator. * Remove any lint left by the cotton-tipped applicator. * If grease and other dirt can be found on other areas of the cradle, use a lint-free cloth and alcohol to remove. * Allow at least 10 to 30 minutes (depending on ambient temperature and humidity) for the alcohol to air dry before applying power to cradle. If the temperature is low and humidity is high, longer drying time is required. Warm temperature and low humidity requires less drying time. **Cleaning Battery Connnectors** * Remove the main battery from the device. * Dip the cotton portion of the cotton tipped applicator in isopropyl alcohol. * Rub the cotton portion of the cotton tipped applicator back and forth across the battery contacts on the bottom of the battery. Do not leave any cotton residue on the contacts. * Repeat at least three times. * Use the cotton tipped applicator dipped in alcohol to remove any grease and dirt near the connector area. * Use a dry cotton tipped applicator and repeat steps 3 through 5. * Spray compressed air on the connector area by pointing the tube/nozzle about ½ inch away from the surface. * Inspect the area for any grease or dirt, repeat if required. * Replace the battery in the device. #### Cautions * After cleaning the cradle connectors with bleach-based chemicals, follow the Cleaning Cradle Connectors instructions to remove bleach from the connectors. * Do not clean the device or expose it to water or moisture when the battery cover is removed. * The following chemicals are known to damage the plastics on the device and should not come in contact with the device: ammonia solutions, compounds of amines or ammonia; acetone; ketones; ethers; aromatic and chlorinated hydrocarbons; acqueous or alcoholic alkaline solutions; ethanolamine; toluene; trichloroethylene; benzene; carbolic acid and TB-lysoform. * The device should not be handled while wearing vinyl gloves containing phthalates, or before hands are washed to remove contaminant residue after gloves are removed. * When using hand sanitizer that contain ethanolamine, hands must be completely dry before handling the device to prevent damage to the device. #### Footnotes * We do not claim that these cleaning processes will annihilate (abridged language) COVID-19 *** *** Did you find it helpful?

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://knowledgebase.flaik.com/flaik-knowledge-base/for-hardware-specialists/scanners/cleaning-and-disinfecting/cleaning-and-disinfecting-guidelines-mc33.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
