GPS Antenna
If the device has a GPS antenna, the following rules apply:
•
When placing antennas avoid easily reached places. Hide antennas
UNDER the dashboard if possible.
•
Please place the GPS-antenna on the dash-board in order to check
the box during installation. After you have got a correct GPS fix you
can fix it.
•
Make sure that the GPS reception of the position is good (no metal
shielding). Not all antennas are optimal for hiding them.
•
Avoid GPS antenna placement under metal surfaces.
•
GPS antenna must be placed so its state is as horizontal as possible
(if antenna is leant more than 30 degrees, it is considered incorrect
mounting).
•
GPS antenna cable cannot be bent more than 80 degrees.
•
GPS antenna must be placed sticker facing down.
•
It is recommended to place GPS antenna behind or under
dashboard as close to the window as possible. A good example of
GPS antenna placement is displayed in a picture below (below area
colored green).
•
If you need accurate GPS data and want to reduce the time to GPS-
Fix, the antenna should be mounted on the dashboard.
Important notice regarding position of GPS Antenna:
Hiding the GPS antenna below the dashboard (near to the front
window) is generally possible according to the producer and must
be tested for each vehicle. Under certain circumstances hiding the
antenna will deteriorate the GPS Fix (the quality of the GPS
position) and could lead to higher power consumption (search for
GPS).
1.9
GSM Antenna
If the device has a GSM antenna, the following rules apply:
•
GSM antenna must be placed with as little metal obstacles around it as possible.
•
Avoid placing GSM antenna near car radio, speakers or alarm systems.
•
After hiding it, a test of GSM/GPRS connection must be done.
Important notice regarding position of GSM/GPRS Antenna:
•
Avoid connections that could cause interference with radio, speakers or alarm systems.
1.10
Power Consumption
Please note that external factors might cause the box to enter sleep mode (searching for GPS, reloading batteries).
Different factors (box operations, antenna positions) will cause different power consumption.
To avoid total battery depletion after very long inactivity you can add a main power switch that can be installed hidden so
that you can disconnect the device from power if needed.
1.11
Installation Tests
Test must be done outside to have a GPS connection. All tests must be done according the instruction.
For devices installed in vehicles:
•
Drive 500 meters, switch off the ignition for minutes, switch it on again and driver back and stop in front of the
workshop if possible.
•
Verify your test using the online data tool
For mobile trackers:
•
Trigger some data points outside
•
Verify your test using the online data tool
