Safety Instructions for Batteries

If the transmitter is left on, and both the steering and throttle haven't been used for ten minutes, a slow beeping alarm will 
sound. To stop the alarm simply move the power switch to the off position. If the combined voltage of the batteries in the 
transmitter drops below 4.8v a quick beeping alarm will sound and the power LED will blink. To stop this alarm replace the 
batteries with four fully charged units - 

DO NOT MIX BATTERIES OF DIFFERENT TYPES OR AGES

 - this will 

result in reduced range and possible loss of control.

1. Use only four(4) AA alkaline batteries in your ATX200/ATX300 transmitter.

2. Do not dispose of the battery in a fire as it may explode. Check with local 

codes for possible special disposal instructions.

3. Do not open or mutilate the battery. Released electrolyte is corrosive and 

may cause damage to the eyes and skin. It may be toxic if swallowed.

4. Exercise care in handling batteries in order not to short the battery with 

conducting materials such as rings, bracelets and keys. The battery or 

conduction material may over-heat and cause burns.

Your transmitter is setup specifi cally for your kit at the factory. This can vary model to model so please consult your full kit 
manual for your specifi c. default settings
