TROUBLESHOOTING GUIDE
The Impact
®
4000 will not show up in the GeoBallistics
®
App in my device.
• Bluetooth
®
modules of a certain age may not be able
to communicate with modern devices. Devices such
as iPhone 6 and older, or Android 4.0 and older,
may not work with the Impact
®
4000.
I have paired my Impact
®
4000 with my device, but they
are not communicating.
• If you have successfully paired before, and the
device and Impact
®
4000 will not communicate,
turn the device on and off on both your device and
on the Impact
®
4000.
My compass will not calibrate.
• If the compass will not calibrate, ensure you are
calibrating the compass outside and away from
buildings, cell towers, or other structures.
• If the Impact
®
4000 calibration is off, then repeat
the calibration. The Impact
®
4000 may need to be
recalibrated when changing geographic location,
typically 30 miles or more.
