FMT-301, FMT-302, FMT-304
Handheld 27MHz Remote Control Digital Transmitter with Buzzer

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 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.

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.
