A. Operation
Install the desired number of batteries and the antenna to make the MRLY operational. The
MRLY should be placed between the transmitter and receiver.
B. Modes of Operation
The MRLY has two modes of operation. These modes are controlled by internal tilt switches.
Normal Operation – The MRLY may be put in normal mode by placing it with the antenna up
on a flat level location.
Power Off – Power is turned off by tilting the unit in any direction past 15°. This mode is used
to transport the relay to the development location to prevent transmission and battery power
drain.

C. RF Link
The operational range of the RF link is dependent upon various conditions. The high frequency
of the RF link works best under line of sight conditions. However, operation from gulches and
around buildings or hills is possible for shorter ranges.
Retransmission ranges of 25 to 100 miles can be achieved.
D. Emplacement Considerations
The MRLY must be placed within the transmission range of the sensor transmitter assembly.
For the best results, place the relay half way between the transmitter and the receiver on a flat
surface or at the top of a hill or building. Elevating the repeater antenna or using a toss up
antenna will greatly increase the operational range.
