Description
The LED indicator on the FMT-401 indicates the low battery (<6.5V) status 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-401 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 operation is achieved by a 12-way code switch (part of the digital encoding system)
which is used in place of the usual 8 or 10 way systems from other manufactures. This enables the user to
select any one of the 4096 codes available. The code can be easily changed at any time.

Using FMT-402 and FMT-404
To Use FMT-402 with a 2 channel receiver, and FMT-404 with a 4 channel receiver, just match the 10 way
dip switch on the transmitter to the receiver.
Using 2 Different Receivers with FMT-402
FMT-402 can also be used with 2 different single channel receivers e.g. FMR-212.
Make sure the 10 way dip switch on the transmitter board matches the first 10 dip switches on the receiver.
Set the receivers dip switch 11 and 12 as described below.
When Button A is pressed, dip Switch 11 is transmitted as “ON” (Dip switch 11 on the Receiver is up)
When Button B is pressed, dip Switch 11 is transmitted as “OFF” (Dip switch 11 on the Receiver is down)
When wire link is connected (Factory default), dip switch 12 is “ON” (Dip switch 12 on the Receiver is up)
When wire link is disconnected (cut), dip switch 12 is “OFF” (Dip switch 12 on the Receiver is down).
(see picture below for the location of the wire link)

Using 4 Different Receivers with FMT-404
FMT-404 can also be used with 4 different single channel receivers e.g. FMR-212. This can be setup as follows:
1. Make sure the 10 way dip switch on the transmitter board matches the first 10 dip switches of the receiver.
2. The receivers dip switch 11 and 12 configuration is illustrated below.
