“AA” batteries.
No power to the
receiver (AC power

connection.
Ensure power input to the receiver
unit is correct. If the power indicator
(AC) is still not lit, please check the

operate correctly.
Receiver configuration is not set
properly or output wiring is incorrect.
Please refer to section 6 and 7
to ensure receiver is correctly wired
