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 leave any cotton residue on
the connector.
4. All sides of the connector should also be rubbed with the cotton-tipped applicator.
CAUTION: Do not point nozzle at yourself and others, ensure the nozzle or tube is pointed away from your face.
5. Spray compressed air in the connector area by pointing the tube/nozzle about ½ inch away from the
surface.
6. Remove any lint left by the cotton-tipped applicator.
7. If grease and other dirt can be found on other areas of the cradle, use a lint-free cloth and alcohol to
remove.
8. 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.
