General Care
Your device is a product of superior design and craftsmanship and should be
treated with care. The following suggestions will help you protect your warranty
coverage.
•
Never immerse the product in water as it is IP53 rated.
•
Do not use or store the device in dusty and dirty areas. Its moving parts and
electronic components can be damaged.
•
Do not store the device in hot areas. High temperatures can shorten the life of
electronic devices, damage batteries and warp or melt certain plastics.
•
Do not store the device in cold areas. It can form moisture inside the device
and damage electronic circuit boards when the device returns to its normal
temperature.
•
Do not drop, knock, or shake the device. Rough handling can break internal
circuit boards and fine mechanics.
•
Do not paint the device. Paint can clog the moving parts and prevent proper
operation.
•
Keep the device free from any small and loose items (such as paper clips,
staples, or coins) that could accidentally get inside it through an opening, such
as the SAM slots or the primary smart card reader slot.
•
Do not attempt to open the device other than as instructed in this guide. This
device has security features that protect it from tampering. For example, the
file content will be deleted if the device’s outer casing is opened.
•
Use only the power adapter that came with your device. Adapters of other
electronic devices may look similar, but they may affect your device’s
performance or damage it.
•
Do not use this device in any area with a potentially explosive atmosphere.
Follow all signs and instructions. Potentially explosive atmospheres include
areas where you would normally be advised to turn off your vehicle engine.
Sparks in such areas could cause an explosion or fire resulting in bodily injury
or even death.
