Troubleshooting Guide

Trouble Locking on to Satellites

If the VBOX 3i SL is having trouble locking onto satellites then please follow the checklist below for typical solutions:

 low)

 Check the antenna connection with the VBOX 3i SL; only small amounts of dirt in the socket can cause a significant reduction in signal strength. Also check

the cable at the plug and along its length for any damage.

 Check that the power supply is connected and free from damage.

 If possible try another known working antenna, to confirm antenna functionality.

 Perform a GPS Coldstart (hold down LOG button for 5 seconds  till it beeps) and then leave the unit powered up in an open static position for at least 15

minutes.

Once the VBOX 3i SL has locked on to 4 or more satellites it will be ready for use.

Trouble getting dual antenna lock

If the DUAL LED is not illuminated (either Green or Orange):

 The slip module is most likely not enabled. Communicate with your VB3i SL using VBOX Tools software. Enter VBOX Setup, then access the GPS tab, and

 After you have pressed this, the box will re-scan, after which the slip module channels will appear selectable as a tab, in

the channels list.

The DUAL LED won’t go Green (permanently Orange), or flashes Green/Orange.

 Check the physical separation between the antennas (centre point to centre point). Does this match up to what has been configured within the VBOX File

Manager.

If the separation is correct, is the location suitable? Try driving to a more open space, free from obstructions or other traffic.

 Check the antenna connection with the VBOX 3i SL; only small amounts of dirt in the socket can cause a significant reduction in signal strength. Also check

the cable at the plug and along its length for any damage. Do not extend the cables in any way when using two antennas.

 Move the antennas away from the edge of the roof, and away from any roof bars or additional antennas.

 Try removing and re-applying power to the box.

 Check that ROLL MODE is not enabled if using a front and rear antenna layout.

 If in ROLL MODE, make sure the primary antenna (Port A) is on the left hand side of the roof.
