Troubleshooting
Power
Should the XRX unit be turned off when starting up the aircraft?
When using aircraft power it is always a good idea to keep any avionics off during startup. Since the aircraft has
only two sources of power, the battery and the alternator, engine starting causes the battery to contribute
considerable amperage to the starter which reduces it’s output voltage below that of acceptable levels for most
avionics. While older, tube-style avionics are not as affected, newer processor-based avionics, such as XRX, may
not deal well with this situation, even though most avionics devices turned on during this time period should
simply reset itself. A potential power surge does pose some risk, however this is not very likely since the output
voltage on most alternators are protected from such.
Occasionally, when the power button is pushed, the unit turns off as soon as the button is released.
This system is turned on through a momentary press of the power button for less than one second. If the power
button is held down for too long, the system will shut off when pressure is released. Press the power button for
no more than one second, then release.
Unit powers on, the display briefly illuminates, then unit immediately shuts off.
Check all connections for proper installation. Unit will shut off automatically if a short in the system is detected.
Unplug all audio connectors and turn on unit. Check to make sure the minimum voltage and current are avail-
able through your power connector, both at the aircraft and at the tip of the power adapter (see Appendices:
Specifications). If unit never starts up, unit needs to be repaired.
Upon powering up, unit displays a garbled or semi-garbled screen, resets, then operates normally.
This is normal and simply means unit was reset (powered off then back on) too quickly. The unit will sense the
improper startup and reset itself.
Traffic Detection
When tracking an aircraft flying overhead, ATC said traffic was less than a mile, but XRX showed the traffic was
2.0 NM. Why the difference in range?
XRX gives range based on true distance in three-dimensional space and is based off of received signal amplitude.
Some aircraft such as airliners have twice the power output of most general aviation aircraft and will appear
closer than in reality.
