Cleaning the Rugged Handheld Computer

25 May 2006

Touchscreen (Display) and Case

 

To clean the touchscreen and case, follow these steps:

  1. Press the power button briefly to suspend the device. Or disable the touchscreen as instructed in the user guide.
  2. If you applied a protector to the touchscreen, carefully remove it by peeling it gently to the side. Peeling it to the side helps prevent stretching the touchscreen layer and reducing tap sensitivity.
  3. Apply water or a mild cleaning solution such as Windex to a microfiber cloth and gently wipe off the touchscreen. Isopropyl alcohol can be used briefly to wipe off the touchscreen, but minimize the time the unit is exposed to it.

    CAUTION: Do not use tissues, paper towels, or harsh cleaning agents to clean the touchscreen.

  4. If you need to clean off tar, pitch, and other compounds, it is recommended to use the Greased Lightning Multi-Purpose Cleaner product.

    Other safe cleaners include:

    * Orange Clean (Orange Glo International)* Fantastik Oxypower (SC Johnson)* Orange Cleaner Oil Eater (Kafko International, Ltd.)* Chain Pro (Midwest Polychem, Ltd.)

    CAUTION: Long term exposure to other solutions may damage your device. Only use the solutions mentioned above.

  5. If you used a cleaning solution, thoroughly rinse off the solution from the touchscreen and case with water and dry it with a microfiber cloth.
  6. Press the power button to resume the device or re-enable the touchscreen.

     

CAUTION: Exposing the touchscreen and/or plastic case parts for an extended period to the following solutions may cause damage:

 

 

Cleaning Charging and Communication (Serial, USB, etc.) Ports

Before cleaning the cleaning charging and communication (serial, USB, etc.) ports, remove the main battery for at least 10 minutes to discharge the device. Once the device is discharged, make sure that card slots, expansion modules, battery compartments, and/or other potentially sensitive areas are tightly sealed.

To clean the ports, remove the rubber stops from the ports and then run the ports under a faucet. Use a soft toothbrush or toothpick to clean out any remaining dirt, and run the ports under a faucet again to rinse out dirt. Dry the ports before re-inserting the rubber stops and battery.
