IMPORTANT!

In order to get the best out of your system it is important you
take the time to read through the manual before you start to
install/program your equipment.

GENERAL INFORMATION

The system works at the frequency 433.92 MHz and uses frequency modu-
lation, generally known as FM.The main benefit of using FM instead of the
more common AM (amplitude modulation), is that FM is less sensitive to
the electrical interference generated in computers, electric motors, etc.
Objects positioned between the transmitter and receiver antenna, espe-
cially large metal objects (such as the reinforcement rods in concrete walls),
can affect the range in a very unpredictable manner, depending on how the
distribution of radio signals takes place.
The influence of other radio transmitters on the same frequency in the vi-
cinity also affects the range. Due to these circumstances it is difficult to give
any general advice other than that free visibility between the transmitter
and the receiver should produce the best the range with an optimal signal.
The normal range for the transmitter in an interference-free environment
is about 50-100 m.
