• Can of compressed air with a tube.

Cleaning Frequency

The cleaning frequency is at the customer’s discretion due to the varied environments in which the mobile

devices are used and may be cleaned as frequently as required. When dirt is visible, it is recommended to

clean the mobile device to avoid build up of particles which make the device more difficult to clean later on.

For consistency and optimum image capture, it is recommended to clean the camera window periodically

especially when used in environments prone to dirt or dust.

Cleaning the Device

Housing

Thoroughly wipe the housing, including all buttons and triggers, using an approved alcohol wipe.

Display

The display can be wiped down with an approved alcohol wipe, but care should be taken not to allow any

pooling of liquid around the edges of the display. Immediately dry the display with a soft, non-abrasive

cloth to prevent streaking.

Camera and Exit Window

Wipe the camera and exit window periodically with a lens tissue or other material suitable for cleaning

optical material such as eyeglasses.
