Note: if the 9 volt battery is installed in the Dashboard, the Dashboard will be powered by the battery even when the USB plug is
connected. If you wish to monitor or record very long runs with Live Mode, turn off all power to the Dashboard and remove the 9
volt battery. Then, the Dashboard will be powered by USB.

Troubleshooting
If your problem is not resolved after carefully reading the following section, visit our support page at
http://www.eagletreesystems.com/Support/support.html
for additional help.
Issue: My Dashboard is receiving data, but it doesn’t look like correct data.
Solution: First, refer to your Recorder manual and read the section pertaining to the incorrectly displaying parameters. Then, verify
that parameters are working correctly with just the Recorder by either making a recording and playing it back, or using Recorder (not
Dashboard) Live Mode.
Solution: Some parameters, like altitude, airspeed and current, are “zero calibrated” each time the Dashboard is turned on. If these
parameters are not zeroed, try turning off and on the Dashboard.
Issue: My altitude or airspeed values seem to drift, even when the model is sitting still
Solution: Some slight drift may occur after flying. Note that for airspeed, which is related to the square of pressure, slight drift from
zero will not affect your higher speed readings much. For example, if your Dashboard is displaying 9 MPH when not moving, the
error at 50 MPH would be closer to 1 MPH, rather than 9 MPH.
Issue: I am unable to successfully complete an “antenna down” range check with the Seagull Transmitter running. I am seeing servo
jitter or observing reduced range during range checking.
Solution: Read the troubleshooting section in the Recorder manual and see if one or more of those solutions resolve the problem.
Solution: First, verify that the problem does NOT happen with the Recorder/Transmitter removed from the plane.
