Maintenance and Troubleshooting 6 - 3
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 dried the display with a soft, non-abrasive cloth to prevent streaking.
Power Connector
1. Remove the main battery from ET5X.
2. Install the battery cover.
3. Dip the cotton portion of the cotton tipped applicator in isopropyl alcohol.
4. Repeat at least three times.
5. Use the cotton tipped applicator dipped in alcohol to remove any grease and dirt near the connector area.
6. Use a dry cotton tipped applicator and repeat steps 3 through 6.
7. Spray compressed air on the connector area by pointing the tube/nozzle about ½ inch away from the surface.
8. Inspect the area for any grease or dirt, repeat if required.
Cleaning Cradle Connectors
Use this procedure to clean the connectors on a cradle:
1. Remove power 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.
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.
CAUTION
Do not point nozzle at yourself and others, ensure the nozzle or tube is away from your face.
