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.
