FMT-302 OPERATING MANUAL27MHz 2-CHANNEL REMOTE CONTROL DIGITAL TRANSMITTERThe hand controller, FMT-302 is part of a two-channel remote control system. A few of itsapplications could be as:The battery service life approximates its shelf life. 9-Volt Carbon or Alkaline type batteries may beused. Depending on the battery type, shelf life ranges between 1 and 2 years. While the FMT-302 isnot transmitting it uses no power. It will operate on as low a 4 Volts DC, however, in such cases thepower and range will be reduced.The highest possible standard of performance is achieved by employing a crystal-controlled, frequencymodulated radio signal operating in the 27MHz band. This is enhanced by a specially dedicatedcustom-built integrated circuit. The latest "state of the art" surface-mount technology (SMD) providesmaximum reliability.A 10-way code switch (part of the digital encoding system) is used. This enables the user to select anyone of the 1024 available codes and thus ensure highest security against false operations. The eleventhswitch is changed by pressing either channel A or B. The twelfth switch is “On” if a wire link is nextto the code switch, if it is removed the twelveth switch is off. This is displayed on the back of thebattery cover of the FMT-302. The code can be readily changed at any time.The maximum operating distance (in conjunction with our FMR series receivers) will average between200 and 250 metres. The operating distance may depend upon the structure of the building in whichit’s used. When operating near its range limit, some improvements may be obtained by pointing thecontroller towards the receiver. This is due to its slightly directional properties.In Australia, a licence issued under the "Wireless Telegraphy Act and Regulations" is not required forthe operation of this transmitter.The housing of the controller has been designed to accept Elsema’s leather pockets.The controller is also available without its front membrane label, to enable the fitting of customersown designed label.• a calling device for the elderly or handicapped.• a personal security alarm activator for home safety or cashcarrying businesses e.g. banks, shops service stations, etc.• a remote control switching device for garage doors, lights,gates and automatic telephone dialer.It is housed in an attractive, high impact resistant grey ABSplastic case.Pressing the designated switch on the front positively activatesthe controller. Activation is confirmed by the sound of its built-in buzzer.
