Troubleshooting
This chapter contains troubleshooting tips for FAST Survey, and the various hardware devices supported by FAST
Survey.
GPS Heights
FAST Survey records GPS heights as the ellipsoid height, expressed in meters, at either the phase center or the ARP of
the antenna, depending on the GPS manufacturer. If the position is recorded to the ARP, then the LS record (antenna
height) will only reflect the user-entered value. If the position is recorded to the phase center, then the LS record
(antenna height) will reflect the user-entered value plus the phase center offset.
Handheld Hardware
How do I reset the computer after a lock up?
Ranger
Hold down the power button until the computer resets or instructs you to hold it for 5 more seconds to reset.
Allegro
Hold down the power button until the computer resets.
Why can’t I load the software?
The computer may disconnect from ActiveSync when there is not enough memory allocated to “Storage Memory”. In
the control panel, select the “System” icon followed by the Memory tab. Position the slider so that there is 5mb (5120
kb) allocated and not in use (i.e. if the “In Use” value says 1024 kb then add 1024 & 5120 to determine what the
“Allocated” value should be).
How do I clear the RAM backup and why?
Clearing the RAM backup seems to improve performance on the Ranger platform after new programs have been
installed or removed. Make sure that all software applications are closed and select the “RAM Backup” icon from the
control panel. Select the Delete button and answer Yes to the three resulting message boxes.
Why can’t I communicate through the COM port?
If you cannot communicate with the instrument, verify all COM settings in FAST Survey and make sure that they match
the COM settings on the instrument. If communication has previously been working and the COM settings have not
been altered, try one of the following to clear up the COM port:
 Exit FAST Survey, turn off the computer, Restart the computer and re-enter FAST Survey.
 Exit FAST Survey and perform a soft reset on the device (Verify that all applications have been closed).
 Exit FAST Survey and perform a hard reset on the device (Verify that all applications have been closed).
How do I set the CAPS LOCK status?
Ranger
1) Hold down the yellow shift button [ ^ ] and the [ALT] buttons, then press and release the power button.
2) A small keyboard should be showing. On the small keyboard, press the [CAPS] button then repeat step 1 to dismiss
the keyboard.
Allegro
Press and release the blue function button followed by the CapLk/Shift button located at the lower left side of the
keyboard.
How frequently should I charge the device?
We recommend starting every day with a fully-charged battery. Refer to your hardware manual for specifics on
charging your battery.
How do I calibrate the touch screen?
In the control panel of the CE device, select the “Stylus” icon to configure the “Double Tab” and “Calibration” of the
touch screen.
How do I turn on/off the back light?
