IMPORTAnT: All Spektrum charge jacks are center-pin
negative. This is the opposite of many chargers. Before
using a charger make sure the connector is center-pin
negative. This can be done using a voltmeter. Also
unlike conventional radio systems that use 8 cells to
power the transmitter, the DX5e uses 4 cells. This is due
to the electronics being more efficient. When charging,
be sure to use a charger designed for a 4-cell 4.8-volt
battery pack when charging the transmitter.
TRAnSMITTER POlARITy
The center pin on all Spektrum transmitters is negative.
Therefore, the center pin on all Spektrum chargers is
negative, not positive. This is different from many other
manufacturers’ chargers and radio systems. Beware of
improper connections based on “color coded” wire leads,
as they may not apply in this instance. You must make sure
that the center pin of your Spektrum transmitter is always
connected to the negative voltage of your charger for correct
polarity hookup.
DIGITAl TRIMS
The DX5e features digital trims. Each time a trimmer is
moved the servo output will change one step. If the trimmer
is held, the output will scroll in that direction until the
trimmer is released or the output reaches its end.

lOw bATTERy AlARM
When the battery voltage drops below 4.7 volts, an alarm
will sound and the voltage LEDs will flash.
TRAInER
The DX5e offers a trainer function that allows the transmitter
to operate as a master or slave. The trainer switch is located
on the back left of the transmitter. When using the trainer
function, plug the trainer cord (SPM6805) into the trainer
port in both the master (controlling) and the slave (training)
transmitters. The master transmitter must have the power
turned on and the slave transmitter must have the power
turned off.
note: The DX5e trainer system is compatible with all
JR and Spektrum transmitters.
MASTER
The DX5e transmitter can be used as a master but the slave
transmitter must have the same programming (i.e. reverse
switch positions) as the master.
SlAvE
When using the DX5e transmitter as a slave with another
DX5e, it’s necessary to match all the reverse switch
positions.
RECEIvER InSTAllATIOn
The AR500 incorporates dual receiver antennas, offering
the security of dual path RF redundancy. By locating these
antennas in slightly different locations in the aircraft, each
antenna is exposed to its own RF environment, greatly
improving path diversity (the ability for the receiver to
see the signal in all conditions). The receiver features two
aileron outputs making it convenient when installing the
receiver in airplanes that have two aileron servos.
RECEIvER InSTAllATIOn
Install the receiver using the same method you would use
to install a conventional receiver in your aircraft. Typically,
wrap the receiver in protective foam and fasten it in place
using rubber bands or hook and loop straps. Alternately, in
electric models, it’s acceptable to use thick double-sided
foam tape to fasten the main receiver in place.
Mount the antennas such that the tip of the feeder (long)
antenna is perpendicular (90 degrees) to the short antenna
and the antennas are at least 2 inches apart. Essentially, each
antenna sees a different RF environment and this is key to
maintaining a solid RF link.
