Problem: The Dashboard displays “Acquiring Fix” on the Lat/Lon LCD Page for more than about 5 minutes.
Solution: Make sure that the GPS has a reasonably unobstructed view of the sky.
Solution: Make sure you have gotten a valid fix before the vehicle starts moving. Moving slows down the acquisition process considerably.
Solution: Some areas have lots of RF Noise, which can increase the length of time required to get a fix.
Solution: On cloudy days, it will take longer to get a fix than on clear days.
Problem: My eLogger V3 shuts off or the LED flashes rapidly when used with the GPS.
Solution: The GPS draws significant current from the eLogger. When the eLogger is powered by a higher voltage pack, such as an 8s or larger
pack, or a pack above 30 volts, the eLogger’s regulator may shut off after a short period when used with the GPS. Please use our “Battery Backup
Harness”, part number CAB-BAT-BACK, to provide supplemental power to the eLogger, if you encounter this issue.
