Cleaning your Motorola WT4090

Housing:

Using the alcohol wipes, wipe the housing including keys and in-between keys.

Cleaning the Wearable Terminal:

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. For WT4090 with touch panel, only use a soft lens cloth to clean the touch panel overlay surface.

Cleaning the Connectors:

Clean all three connectors, two interface connectors on the sides of the wearable terminal and the cradle connector on the back.

  1. Remove the main battery from mobile computer.
  2. Remove connector rubber plugs, if required.
  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 each connector. 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 7.
  8. Spray compressed air on the connector areas by pointing the tube/nozzle about ½ inch away from the surface.
  9. Inspect the area for any grease or dirt, repeat if required.
  10. Replace connector rubber plugs, if required.

Cleaning Cradle Connectors:

  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.

Cleaning Frequency:

The 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 ring scanners’ exit windows to ensure optimum scanning performance.
