USING THE TRANSMITTER

Antenna

The transmitter antenna bends and turns at the hinge (A) and only bends and turns to the front of the transmitter. The antenna cannot point to the back of the transmitter. Turn the antenna tip to point away from the model and ground. Signals transmit strongest from the antenna shaft, not the tip.

WARNING: Do not pick up the transmitter by the antenna.

Do not alter or put weight on the antenna. Damage to antenna parts can decrease transmitter signal strength, which can result in loss of model control, injury or property damage.

NOTICE: While DSMX allows you to use more than 40 transmitters simultaneously, when using DSM2 receivers, DSMX receivers in DSM2 mode or transmitters in DSM2 mode, do not use more than 40 transmitters simultaneously.
