Safety Notes and Maintenance
Introduction
This section of the User Manual contains some general information and
recommendations related to the use of your Hema HN7 NAVIGATOR.
Operating Environment
External Influences
•
Do not allow objects to drop onto the device from above.
•
Do not place objects on top of the device or rub the screen with abrasive
materials or objects such as car keys etc.
•
Do not drop the device.
•
Do not use sharp or abrasive objects to operate the touch screen other
than the stylus designed for this purpose.
•
Avoid prolonged use in high vibration and high shock environments.
•
Do not carry/transport flammable liquids, gases or explosives in the
same compartment as the device and its accessories.
•
Wireless devices can interfere with the reception of satellite signals
causing unstable signal reception.
•
Some car audio systems can cause interference with the device.
GPS
•
This system uses GPS signals produced and monitored by the United
States government, who are solely responsible for the availability and
accuracy of the system.
•
GPS satellite signals do not penetrate solid objects (apart from glass)
and, therefore will not operate from within a building unless an external
re-radiating GPS antenna is fitted.
•
GPS signal reception may be impaired by dense obstacles above the
ground such as tall buildings, trees, or extremely bad weather.
•
In order to operate efficiently, the Hema HN7 NAVIGATOR should be
positioned with a view to the open sky (through glass is acceptable).
•
Glass with a metallic film, as fitted on some vehicles, may impair the
GPS signal. An external automotive re-radiating GPS antenna may be
required.
Temperature
•
Do not leave your Hema HN7 NAVIGATOR lying or mounted on your
dashboard where it will be exposed to extreme temperature conditions
which can result in malfunctions and/or dangerous situations. The
device may be operated in a temperature range of 0°C - 45°C or stored
in a temperature range of 0°C - 35°C.
•
Keep the device away from moisture and excessive dust. The device
should be used in an atmospheric humidity (non-condensed) of 45% -
80% and stored in an atmospheric humidity of 30% - 90%.
•
Do not expose the device to sudden and extreme temperature
fluctuations. This may result in condensation forming within the device
causing malfunction or failure. When condensation forms, wait for the
device to completely dry out before operating.
