VBOX Micro
GPS Coldstart
A GPS coldstart forces the GPS engine to reset its downloaded almanac of current satellite positions. This can be useful if the VBOX Micro is having trouble
locking onto satellites, which typically occurs if the VBOX Micro 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 VBOX Micro powered up in a static location where the antenna has an unobstructed view of the skies, for at least
fifteen minutes.
Once the VBOX Micro 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.
There are two ways to perform a GPS coldstart on the VBOX Micro, one with and one without the use of a computer.
Without a computer:
Press and hold the square button '■' on the side of the VBOX Micro for five seconds. The unit will then beep to indicate that the GPS coldstart is underway.
With a computer:
To coldstart the GPS engine in the VBOX Micro using a computer, connect the VBOX Micro
to the computer via USB cable and run the VBOX Micro set up software, is supplied with the
unit. Press 'Read Settings' to start communications, then open the 'Options' menu and select
the 'ColdStart' option. The unit will beep to confirm that the cold start is being performed.
