InsTallIng The baTTerIes

The DX3S 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.

Optional NiMH 1.2-volt AA rechargeable batteries

(SPM9525) can also be used. A charge jack located opposite of the on/off switch is provided for convenient recharging with Spektrum charger SPM9526.

Remove the battery door and install 4 AA batteries observing the polarity marked on the battery holder.

Replace the battery door.

SPEKTRUM DX3S USER GUIDE

A charging jack is located on the opposite side of the on/ off switch. If rechargeable batteries are used they can be conveniently charged without removing them from the transmitter using the charge jack. Use Spektrum’s charger

(SPM9526) to charge rechargeable batteries in the DX3S.

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 DX3S 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.
