Video VBOX LITE not responding - GPS Coldstart
The GPS engine has locked up.
Perform a GPS Engine Coldstart
A GPS coldstart forces the GPS engine to reset its downloaded almanac of current satellite positions. This can be
useful if the Video VBOX LITE is having trouble locking onto satellites, which typically occurs if the Video VBOX LITE has
not been used for several weeks or if it was last used a long distance (over one thousand miles) away from the current
location.
After performing a GPS coldstart leave the Video VBOX LITE powered up in a static location where the antenna has an
unobstructed view of the skies until the ‘GPS’ LED becomes solid green. Once the Video VBOX LITE has downloaded
the new almanac it will reacquire satellites in noisy situations (such as near trees, buildings and under bridges) much
more quickly. It will also acquire satellite much more quickly on power-up.
To perform a GPS coldstart on the Video VBOX LITE perform the following actions:
Press and hold the round grey ‘RECORD’ button on the front of the Video VBOX LITE for five seconds.
When the button is released the ‘GPS’ LED will flash green as the Coldstart is being performed.
After approximately 30 secs the ‘GPS’ LED will light solid green indicating satellite lock has been achieved.
