MECHANICS AND ENVIRONMENTAL
EFFECTS
Sight
The device must have an unobstructed view to satellites at
any time.
The device can be used like a standard GSM phone. In some
cases, the device can be built in clothes or special vests.
If the device is mounted somehow, it must be attached to
the surface so that the back of the device is facing up. To en-
sure proper functioning of the GPS, the GPS antenna can be
covered with plastic, fiber glass or clothes, but not with met-
al.
In marginal conditions an external GPS antenna, possibly
even a GSM antenna, must be installed.
Temperature ranges
•
Usage
: -20 to +55 °C with a standard Li-Ion battery

Charging
: Standard Li-Ion battery must not be charged
below °0. Likewise, charging above +55 °C is prevented.
At temperatures below -25 °C, or above +60 °C, the battery
will not supply power and the device cannot be used.
Upon warming up/cooling down, the device will function
properly again.
Mechanical durability
The device is dust and splash proof. The protection category
for the device is IPX4.
To meet these requirements, the rubber seal must be insert-
ed in place correctly.
