1)  Slide the battery cover in the direction as shown to remove the cover.
2)  Install 6pcs alkaline or rechargeable “AA” size cells into the battery holder connected to the transmitter.
3)  Slide on the battery cover and make sure it is closed securely. 
4)  Turn the power on to check. If the Power Indicator LED fails to light, check the batteries for insufficient contact 

or incorrect battery polarity.

 CHECK:

a)  Use only fresh, alkaline cells, all of the same brand. 
b)  Make certain that the contacts in the battery holder stay clean by using a pencil eraser to gently remove any 

corrosion or dirt that may accumulate on them. It is recommended to do this each time you install fresh cells 
into your transmitter.

c)  If using the rechargeable battery pack, simply remove the battery holder by pulling out the connector from the 

transmitter. Then plug-in the battery pack connector to the transmitter.

d)  When the rechargeable battery is installed in the transmitter, it can be charged through the external charging 

jack located on the transmitter.

CAUTION: 

a)  Do not attempt to charge alkaline batteries, they may explode!!
b)  When charging the rechargeable battery, set the power switch on “OFF” position before charging. The charger 

plug must be correct type (“+” inside and “-” outside, type TAMIYA N-3U or equivalent). The wrong type may 
burst causing personal injury and damage.

c)  Always be sure the batteries are loaded in the correct polarity order. If the batteries are loaded incorrectly, the 

transmitter may be damaged.

d)  When the transmitter is not used for any short or long period of time, always remove the batteries from the 

transmitter.

Make sure the batteries are located in the correct polarity 
order. Maintain the battery contacts in the same way as 
described in previous section.
