Warning
Do not connect the housing to Ground externally. This will suspend the reverse voltage protection of
the power supply. Applying a reversed voltage in this case will destroy the supply circuits.
To avoid damage to the device, connect/disconnect the main connector only if the power supply to
the device is switched off.
To maximize the performance of the GPS receiver, mount the GPS antenna in a place where it is level
with the local geographic horizon and has full view of the sky above. If you are using separate
GSM/3G and GPS antennas, mounting them at least 2 meters away from each other will also help to
improve the GPS performance.
