GPS system attached through the USB (in serial protocol) or
multi-pole connector.
ANT FAIL
- There has been an antenna failure or the antenna is not
connected.
If a survey point is stored with a BAD or OLD GPS position, the position displayed is likely
to be that of the previous point. This would create a distance of zero. C-SCAN recognises
this and will not allow the operator to use the GPS position when entering the distance;
however it will be recorded. The operator must then enter the distance manually, or go
back to the SEARCH screen and wait for GPS acquisition.
Loss of GPS acquisition is usually caused by the GPS antenna being temporarily
obscured; either by buildings or being inside a vehicle. Ensure that the top of the Detector
has a clear view of the sky so that it can ‘see’ the satellites to receive the GPS signal.
When a survey is conducted in the open where the operator walks between survey points,
it would make sense not to turn off the Detector; however, this reduces battery life. A
power saving mode has been introduced that enables the GPS unit to remain on whilst all
other devices are switched off. To enter this mode press the ON-Off key ( ) with GPS still
on. A message will be shown enabling the unit to be switched to Power-Save mode with
the GPS left running in the background. This occurs only if the GPS is on prior to
switching off the Detector. A 30 second countdown will be shown, during which the
display will be active and any key press will re-start the Detector. After 30 seconds the
screen will shut down but the GPS will continue running; this is indicated by the flashing
red LED. After a total of 10 minutes (600 seconds) the Detector will shut down completely.
