LED indicators
The green LED (ST) is used to indicate the number of satellites currently in lock. If the yellow LED (SC) is flashing
whilst the green (ST) LED is off, then the VBOX has no satellite lock.
If this is the case then check that you have the GPS antenna connector correctly fitted to the VBOX. Also check that
the antenna has a clear view of the sky.
The VBOX will normally lock onto satellites within 30 seconds of power up. However on its first use it can take up to
20 minutes to acquire satellite lock.
