Description
Buzzer indicates the status of the transmitter. To activate the transmitter, simply press the button at the front.
Buzzer will be on when the transmitter is activated.
Working in the 27MHz band, the FMT-301 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.
Operating Distance
An operating distance (in conjunction with our FMR series receivers) of 200 metres is possible.
The operating distance depends upon the receiver antenna and location. An independent test revealed the
following ranges:
Range (m) Receiver Antenna Receiver Type
40 250mm wire FMR-… series
Up to 200 ANT27M FMR-… series
Range tests were done in an open area test site with line-of-sight operation and the receiver antenna wire was
fixed vertically, away from any metal objects.
When operating near its range limit, some improvements may be obtained by pointing the transmitter towards
the receiver. This is due to its slightly directional properties.

Using FMT-302 and FMT-304
To Use FMT-302 with a 2 channel receiver, and FMT-304 with a 4 channel receiver, just match the 10 way
dip switch on the transmitter to the receiver.
Using 2 Different Receivers with FMT-302
FMT-302 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-304
FMT-304 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.
The channel coding figure can be found at the back of the battery cover.
