5 SPEKTRUM DX3E USER GUIDE
InsTallIng The baTTerIes
The DX3E radio system is supplied with 4 AA alkaline
batteries required for operation that provide over 16
hours of run time. Many drivers prefer alkaline batteries
over rechargeable batteries finding it more convenient to
simply replace the batteries when depleted rather than
taking the time to recharge.
To install the batteries:
Remove the battery door and install 4 AA batteries
observing the polarity marked on the battery holder.
Replace the battery door.

Optional NiMH 1.2-volt AA rechargeable batteries
(SPM9525) can also be used. If rechargeable batteries
are used, they can be conveniently charged without
removing them from the transmitter by using the charge
jack located on the back side of the transmitters base.
Use Spektrum’s charger (SPM9526) to charge
rechargeable batteries in the DX3E.
IMPORTANT: All Spektrum charge jacks are
center-pin negative. This is 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 DX3E uses 4 cells.
This is due to the electronics being more
efficient. When charging, be sure to use a
charger designed for 4 cells (a 4.8-volt battery
pack) when charging the transmitter. Many
drivers simply make a harness and use the
same charger used to charge their car packs
but turn the current rate down to 1 to 2 amps.
Warning: Charge only rechargeable batteries. Non-
rechargeable batteries may burst causing injury to
persons and/or damage to property.
