Installing the unit
Practical installation advice
• It is very important to be careful when installing the unit, as incorrect
installation will reduce the quality of the GPS position reports (Ex. could be a
jump in position or showing speed while parking) or in the worst case
scenario will prevent the unit performing any position reporting at all.
The unit must NOT be installed beneath metal plates or inside closed metal
compartments. Incorrect installation will also reduce the standby time of the
battery inside the unit.
•
The unit must be mounted either horizontally or vertically (sideways) using either
screws or strips. The unit must not be installed with the interface/supply cable
hanging down, as this definitely will reduce the GPS sensitivity.
Optimize the placement of the unit to increase the aerial view (through windows
etc.) as much as possible. For hiding the unit, make sure it is only mounted beneath
plastic parts or similar parts (wood), but not beneath metal parts.
•
To reduce hum and noise in the FM radio it is recommended to place the unit at a
minimum distance of 20 inches (50 cm) from the radio or the loudspeakers.
