The unit cannot acquire satellite connection
Check that the 3Zero’s built in GPS antenna has a clear view of the sky above.
If this is the first time you have powered up your 3Zero please remember that the first ‘cold’ start can take up to 30 minutes to
acquire sufficient satellite connection. The unit requires time to calibrate and you will find that with subsequent use that the time for
acquiring satellites will reduce. Eventually the unit should take approximately 90 seconds to acquire satellite connection.
Disconnect and reconnect the power to the unit and start the power up procedure again.
Check that the windscreen has not been specially treated to reflect UV rays (Metal Oxide, Athermic, solar reflective). Please check
with the local vehicle dealer or manufacturer to ascertain what type of windscreen is fitted to your vehicle. If you do have this type of
windscreen place the 3Zero where there is a clear section of glass usually situated near the rearview mirror or near the centre of the
windscreen just above the dashboard. If you do not have clear section on the windscreen then unfortunately the 3Zero will not work
in that vehicle.
The satellite signal temporarily or permanently drops out
This may happen temporarily in areas where there are a significant number of tall buildings or trees or whilst driving through a
tunnel. The signal should only be lost for a few seconds and then quickly reacquired.
Check that the device has not moved and that the built in GPS antenna still has a good clear view of the sky above.
Very occasionally you may experience bad satellite coverage that may lead you to loosing a signal. This should last no longer than a
few minutes.
If you have a specially treated windscreen some manufacturers leave a small section of the windscreen untreated. If the unit is not
positioned properly in this untreated area then the unit may loose satellite signal frequently. Reposition the unit within this untreated
area.
The device does not appear to respond to Police speed monitoring systems
Have you performed a download recently? If not, perform a fresh download to ensure that you have all the latest coordinates stored
on your device.
Check that the unit is positioned in such a way that the lens has a clear view of the road ahead and is unobstructed by any metallic
objects (such as windscreen wipers). The laser lens at the rear of the unit, this must also be unobstructed.
