The LED indicator on the FMT-402 indicates the low battery (<6.5V) status alert by flashing at 1Hz. To activate the transmitter, simply press the button at the front. LED will be “on” when the transmitter is activated.
Working in the 27MHz band , the FMT-402 achieves the highest possible standard of performance by employing a crystal-controlled, frequency modulated radio signal. The microcontroller with the latest surface-mount technology provides maximum reliability.
High security against false operations is achieved by a 12-way code switch (part of the digital encoding system) is used in place of the usual 8 or 10 way systems of other manufactures. This enables the user to select any one of the 4096 codes available. The code can be easily changed at any time.
