Device Cleaning Instructions
Do not apply liquid directly to the device. Dampen a soft cloth or use pre-moistened wipes. Do not wrap the
device in the cloth or wipe, instead gently wipe the unit. Be careful not to let liquid pool around the display
window or other places. Before use, allow the unit to air dry.
NOTE: For thorough cleaning, it is recommended to first remove all accessory attachments, such as hand
straps or cradle cups, from the mobile device and to clean them separately.
Special Cleaning Notes
The device should not be handled while wearing vinyl gloves containing phthalates, or before hands are
washed to remove contaminant residue after gloves are removed.
If products containing any of the harmful ingredients listed above are used prior to handling the device,
such as hand sanitizer that contain ethanolamine, hands must be completely dry before handling the
device to prevent damage to the device.
IMPORTANT: If the battery connectors are exposed to cleaning agents, thoroughly wipe off as much of the
chemical as possible and clean with an alcohol wipe. It is also recommended to install the battery in the
terminal prior to cleaning and disinfecting the device to help minimize buildup on the connectors.
When using cleaning/disinfectant agents on the device, it is important to follow the directions prescribed by
the cleaning/disinfectant agent manufacturer.
Cleaning Materials Required
• Alcohol wipes
• Lens tissue
• Cotton-tipped applicators
• Isopropyl alcohol
• 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.
