Chapter 8 Maintenance & TroubleshootingIntroductionThis chapter includes instructions on cleaning and storing the MC75A, and provides troubleshooting solutions for potential problems during MC75A operation.Maintaining the MC75AFor trouble-free service, observe the following tips when using the MC75A:•Do not scratch the screen of the MC75A. When working with the MC75A, use the supplied stylus or plastic-tipped pens intended for use with a touch-sensitive screen. Never use an actual pen or pencil or other sharp object on the surface of the MC75A screen.•A screen protector, p/n KT-67525-01R, is applied to the MC75A. Motorola recommends using this to minimize wear and tear. Screen protectors enhance the usability and durability of touch screen displays. Benefits include:•Protection from scratches and gouges•Durable writing and touch surface with tactile feel•Abrasion and chemical resistance•Glare reduction•Keeping the device’s screen looking new•Quick and easy installation.•The touch-sensitive screen of the MC75A is glass. Do not to drop the MC75A or subject it to strong impact.•Protect the MC75A from temperature extremes. Do not leave it on the dashboard of a car on a hot day, and keep it away from heat sources.•Do not store or use the MC75A in any location that is dusty, damp, or wet.•Use a soft lens cloth to clean the MC75A. If the surface of the MC75A screen becomes soiled, clean it with a soft cloth moistened with a diluted window-cleaning solution.•Periodically replace the rechargeable battery to ensure maximum battery life and product performance. Battery life depends on individual usage patterns.DRAFT

Maintenance & Troubleshooting 8 - 3•Severe impact from dropping any battery-operated device on a hard surface could cause the battery to overheat.•Do not short circuit a battery or allow metallic or conductive objects to contact the battery terminals.•Do not modify or remanufacture, attempt to insert foreign objects into the battery, immerse or expose to water or other liquids, or expose to fire, explosion, or other hazard.•Do not leave or store the equipment in or near areas that might get very hot, such as in a parked vehicle or near a radiator or other heat source. Do not place battery into a microwave oven or dryer.•Battery usage by children should be supervised.•Please follow local regulations to promptly dispose of used re-chargeable batteries.•Do not dispose of batteries in fire.•Seek medical advice immediately if a battery has been swallowed.•In the event of a battery leak, do not allow the liquid to come in contact with the skin or eyes. If contact has been made, wash the affected area with large amounts of water and seek medical advice.•If you suspect damage to your equipment or battery, contact Motorola Enterprise Mobility support to arrange for inspection.CleaningMaterials Required•Alcohol wipes•Lens tissue•Cotton tipped applicators•Isopropyl alcohol•Can of compressed air with a tube.Cleaning the MC75AHousingUsing the alcohol wipes, wipe the housing including keys and in-between keys.WARNING!Avoid exposing this product to contact with hot oil or other flammable liquids. If such exposure occurs, unplug the device and clean the product immediately in accordance with these guidelines.CAUTION Always wear eye protection.Read warning label on compressed air and alcohol product before using.If you have to use any other solution for medical reasons please contact Motorola for more information.DRAFT

Immediately dried the display with a soft, non-abrasive cloth to prevent streaking.Scanner Exit WindowWipe the scanner exit window periodically with a lens tissue or other material suitable for cleaning optical material such as eyeglasses.Connector1. Remove the main battery from mobile computer. See Replacing the Main Battery on page 1-9.2. Close battery door.3. Dip the cotton portion of the cotton tipped applicator in isopropyl alcohol.4. Rub the cotton portion of the cotton tipped applicator back-and-forth across the connector on the bottom of the MC75A. Do not leave any cotton residue on the connector.5. Repeat at least three times.6. Use the cotton tipped applicator dipped in alcohol to remove any grease and dirt near the connector area.7. Use a dry cotton tipped applicator and repeat steps 4 through 6.8. Spray compressed air on the connector area by pointing the tube/nozzle about ½ inch away from the surface.9. Inspect the area for any grease or dirt, repeat if required.Cleaning Cradle ConnectorsTo clean the connectors on a cradle:1. Remove the DC power cable from the cradle.2. Dip the cotton portion of the cotton tipped applicator in isopropyl alcohol.3. 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 let any cotton residue on the connector.4. All sides of the connector should also be rubbed with the cotton tipped applicator.5. Spray compressed air in the connector area by pointing the tube/nozzle about ½ inch away from the surface.6. Ensure that there is no lint left by the cotton tipped applicator, remove lint if found.7. If grease and other dirt can be found on other areas of the cradle, use lint free cloth and alcohol to remove.CAUTION Do not point nozzle at yourself and others, ensure the nozzle or tube is away from your face.CAUTION Do not point nozzle at yourself and others, ensure the nozzle or tube is away from your face.DRAFT

Maintenance & Troubleshooting 8 - 58. 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 dry humidity requires less drying time.Cleaning FrequencyThe cleaning frequency is up to the customer’s discretion due to the varied environments in which the mobile devices are used. They may be cleaned as frequently as required. However when used in dirty environments it may be advisable to periodically clean the scanner exit window to ensure optimum scanning performance.TroubleshootingMC75ATable 8-1 Troubleshooting the MC75AProblem Cause SolutionMC75A does not turn on.
