Plugging in the Leads
Plug the servo leads into the appropriate servo ports in the receiver noting the polarity of the
servo connector.
Red LED Hold Indicator
The AR8000 features a red LED that indicates the number of holds that have occurred since
the receiver was last powered on. The LED will flash the number of holds then pause (e.g.,
flash, flash, flash, pause, flash, flash, flash, pause indicates three holds occurred since the
receiver was last turned on). Note that holds are reset to zero when the receiver is turned off.
During the first flights of a new airplane, it’s recommended to check the red LED hold indicator.
If it’s flashing, it’s important to optimize the installation (move or reposition antennas) until no
hold occurs. On later flights, the LED Hold Indicator can be used to confirm RF link performance.
Range Testing
Before each flying session and especially with a new model, it is important to perform a range
check. All Spektrum aircraft transmitters incorporate a range testing system which, when
activated, reduces the output power, allowing a range check.
30 paces (90 feet/28 meters)
1. With the model restrained on the ground, stand 30 paces (approx. 90 feet/28 meters) away
from the model.
2. Face the model with the transmitter in your normal flying position and place your
transmitter into range check mode.
3. You should have total control of the model with the button depressed at 30 paces (90
feet/28 meters).
4. If control issues exist, call the Product Support Team in the U.S. at 1-877-504-0233 for
further assistance. In the UK or Germany use one of the following contacts.

Advanced Range Testing
For sophisticated models that have significant conductive material in them, the advanced range
test using a flight log is recommended. The advanced range check will confirm that the internal
and remote receivers are operating optimally and that the installation (position of the receivers)
is optimized for the specific aircraft. This Advanced Range Check allows the RF performance of
each receiver to be evaluated and to optimize the locations of the remote receiver.
Advanced Range Test
1 Plug a Flight Log (SPM9540 - optional) into the Batt/Data port on the AR8000 and turn on
the system (Tx and Rx).
2. Advance the Flight Log until F-frame losses are displayed by pressing the button on the
Flight Log.
3. Have a helper hold your aircraft while observing the Flight Log data.
4. Standing 30 paces away from the model, face the model with the transmitter in your
normal flying position and put your transmitter into range test mode. This causes reduced
power output from the transmitter.
5. Have your helper position the model in various orientations (nose up, nose down, nose
toward the Tx, nose away from the Tx, etc.) while your helper watches the Flight Log
noting any correlation between the aircraft’s orientation and frame losses. Do this for 1
minute. The timer on the transmitter can be used here.
