SPEKTRUM DX3E USER GUIDE

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. Nonrechargeable batteries may burst causing injury to persons and/or damage to property.
