1. Remove the main battery from the mobile computer.
2. Dip the cotton portion of the cotton-tipped applicator in isopropyl alcohol.
3. To remove any grease or dirt, rub the cotton portion of the cotton-tipped applicator back-and-forth across
the locating magnet and the connectors on the battery and terminal sides. Do not leave any cotton residue
on the connectors or magnet.
4. Repeat at least three times.
5. Use a dry cotton-tipped applicator and repeat steps 3 and 4. Do not leave any cotton residue on the
connectors or magnet.
6. Inspect the area for any grease or dirt and repeat the cleaning process if necessary.
CAUTION: After cleaning the battery connectors or locating magnet with bleach-based chemicals, follow the
Battery Connector and Locator Magnet Cleaning instructions to remove bleach from the connectors and
locating magnet.
Cleaning Cradle Connectors
To 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 leave any cotton residue on
the connector.
4. All sides of the connector should also be rubbed with the cotton-tipped applicator.
5. Remove any lint left by the cotton-tipped applicator.
6. If grease and other dirt can be found on other areas of the cradle, use a lint-free cloth and alcohol to
remove.
7. 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.
CAUTION: After cleaning the cradle connectors with bleach-based chemicals, follow the Cleaning Cradle
Connectors instructions to remove bleach from the connectors.
