Cleaning the Case
To clean the case, it is recommended that you use warm water,
mild detergent, and a toothbrush.
Note: This method can be used when cleaning the keyboard. Do not
use the brush on the display, it could be scratched.
Cleaning the Keyboard
Dirt and debris can get underneath the keyboard bezel. To
clean, use a coin (do not use a screwdriver) to pry the bezel up
at the recess located at the bottom of the keyboard.
We recommend that you use warm water, mild detergent,
and a toothbrush to clean the keyboard. The Field PC remains
sealed during this process.
Note: Do not direct a high pressure stream of water at the keyboard to
clean it. This action could break the seal, causing water to get inside
the Field PC.
