equipment which would serve as an ideal location for the FM 4310i unit. The following positioning
guidelines should be adhered to:
1.2.1. Avoid mounting the unit directly underneath steel or metal structures such as dashboard
strengtheners, steering columns or large electronic modules
1.2.2. Ideally, the FM 4310i unit should have an unobstructed (not obstructed by metal
– plastic is
a
cceptable) ‘view’ to a large portion of the ‘sky’ through the windows of the vehicle. The windscreen or
rear window is best for this purpose)
1.2.3. When mounting the unit under the dashboard, try to position the unit as high up as possible
– in other
words, as close to the top surface of the dashboard as possible.
1.2.4. Exposure to direct sunlight or positions of extreme ambient heat should be avoided as the FM 4310i
safety features will temporarily shut the unit down under extreme heat conditions.
1.3. The GSM and GPS antennae are built into the FM 4310i unit. Although both antennae were designed for
‘indoor’ use, for optimum operation the mounting position of the unit requires some special consideration as
described below.
1.4.
The GPS/GSM antennae must face ‘upwards’ – this means the plastic mounting tags must be at the
bottom and the ‘serial number sticker’ must be at the top.
The GSM antenna is to be mounted further than
20cm away from the human body under normal operating conditions.
1.5. Once you are satisfied that you have found an ideal mounting position, follow the instructions below to
verify and test the chosen position, by doing an initial electrical self-test to verify the suitability of the
installation position.
2. Verify and test the chosen position
No special test equipment is needed for installation. The FM 4310i harness has a built-in speaker which will assist
you through the self-test process. To achieve this, the unit can be switched to "Diagnostic Mode" during installation
which will play the relevant voice prompts to assist you. The following steps are recommended:
2.1. Move the vehicle into the open air, ideally a short distance away from buildings, overhangs, large clusters
of trees or other structures that may obscure direct signals from GPS satellites and GSM towers.
2.2. Before the unit is secured, power up the unit.
Tip:
A temporary harness using 12v from the vehicle’s
cigarette lighter is ideal for this purpose.
2.3. After
a short pause, the FM 4310i unit will ‘wake up’. switch the FM 4310i into Diagnostic Mode by pressing
the Shift (up arrow) button on the Remote Control Unit followed by the Alert (orange) button repeatedly until
‘Diagnostic Enabled’ is heard. (Also refer to Troubleshooting Chart 1 and 2 below)
2.4. Once you are in Diagnostics mode, place the unit into Self-test Mode by pushing the Shift (up arrow) button
followed by the OK button. A Voice Prompt will ask you to confirm by pushing the OK button again
– do so
when prompted.
2.5. The unit is now in Self-test mode. For the time being, disregard all the Voice Prompts that follow and wait
for the FM 4310i to report the number of satellites visible and GSM signal strength. This happens at the end
of the Self-test routine and is repeated every few seconds until Self-test mode is exited.
2.6. With the vehicle In the location you have selected:
2.6.1.
The unit’s GPS receiver should acquire lock within a few minutes (< 3 minutes typically but a ‘cold’
start may take a little longer)
2.6.2.
The unit’s GPS receiver should see at least five or more satellites within a few minutes.
2.6.3. The unit
’s GSM module should have a GSM signal strength of ideally more than 60%, but not less
than 40% to 50%. (This is obviously also dependant on the general GSM signal strength in the area
and distance from the closest GSM service provider tower)
