Located on the left-hand side of the transmitter is the charging jack, which accepts only
JR ® or Spektrum ™ style wall chargers. Please do not attempt to use any other brand of wall
charger as it may be the reverse polarity and can cause damage to your system. Only use the
JR or Spektrum type wall charger when the DX3.0 is equipped with NiMH batteries.
Warning: Charge only rechargeable batteries. Non-rechargeable batteries may burst
causing injury to persons and/or damage to property.

Please note that DSM2 and marine compatible transmitters can be identified by the following
logo located on the back of the transmitter:
Note: When using a separate NiMH receiver as a power source, the operating voltage
range is 4.8–6.0V (4–5 cells) under load.
Attention: Make sure the male and female connectors have the correct polarity (+/–)
before connecting. Be sure to orient the servo plug correctly for proper insertion.
Most electronic speed controllers are set up for BEC (Battery Elimination Circuitry) operation
and plug directly into your receiver. See Figure A for a typical setup and check your speed
controller’s manual for correct installation.
