The transmitter has an ergonomic fine shape and gives a pleasant handling to the user.

For the trasmitters are available 2 different coding systems, fully compatible:

Preset in factory selected by keys (Erone 30SL): Fixed code, preset in-factory with different codes among the 19683 possible combinations. In programming mode, the transmitter keys allow to personalise the code. This programming method allows to program the transmitter code onto the receiver without to unpack the transmitter.

Coding type selected by dip switch (Erone 30DP): Fixed code, the coding can be done by composing the own code on the Three-state 9 ways Dip-switch which allows 19683 code combinations.The transmitter are all sold with the same code; it is highly advisable to set the personal code on the dip-switches. In a second time the same code has to be stored into the receiver memory using a self-learning method. The security code can be modified in a second time, as well. Each variation will request a new memorisation onto the receiver.
