5. ALIGNMENT

The transmitter and receiver must be aligned to ensure the proper
function of the device.
Perfect alignment is achieved when the optical axes of the first and last
beam from the transmitter meet the optical axes of the corresponding
elements on the receiver.
Two yellow LEDs on the receiver, "HIGH ALIGN" and "LOW ALIGN",
simplify the alignment process.
