Description
The FMT15108H is a hand held 8 channel transmitter that has an operating range of up to 800 metres. With 100mW transmission power and only using 85mA during transmission makes it ideal for the standard 9 volt battery.
Each transmitter button is individually transmitted to the receiver making it possible to do simultaneous channel transmission. This means that up to 8 different functions can be done at the same time. Each button can operate any FMR151… series receivers making it possible to transmit each button to different single channel receivers or to multi channel receivers.
The transmitter uses a frequency of 151MHz and a modulation type of Narrow Band Width FM which makes it suitable for industrial applications where you would have a high level of electrical interference. This transmitter is not affected by man made or electrical interference.
The transmitter uses a specially programmed micro-controller which ensures the highest reliability, low standby current consumption (10uA) and greater flexibility. The greater flexibility allows customers to contact Elsema and request custom written software for special functions.

Coding Instructions
The 12 way dip switch on the transmitter sets the 12 bit unique code for the system. This has to be matched to the receivers 12-way dip switch.
Operating Frequency
There are 7 selectable frequencies available. The black 3-way dipswitch changes the frequency. If two separate systems are installed in the same location it is recommended to set each system to a different frequency. The default setting is 151.600 MHz (All 3 dipswitches "ON”). Following is a table with the Dipswitch settings and the corresponding frequencies.
