Symptom 1,Z: Absolutely No Functlonallty (How to determine which
comr,,onent ts at fault)
Comaonent to Test Instructions
With a Multimeter, measure the DC Voltage of the
supply while it is connected to the Connecting Block.
Put the Negative lead of the meter on the terminal
marked GND and the Positive Lead on the terminal
marked 12VDC (or V). You should get a reading
between 11.5VDC and 13.0VDC. If not, remove the
supply from the Connecting block and measure again
1. Verify Power Supply this time directly on the 2.5mm Coaxial plug. If it
reads between 11.5VDC and 13VDC, power supply is
most likely good. Reconnect to the Connecting Block
and proceed to step 2. NOTE: In most cases this
will indicate the supply is good but in some cases
the supply can still be bad (i.e. reads good when
not plugged in but may not be able to handle the
current load of the system.)
Remove the power supply from the connecting block

ONLY)
Reconnect the Power Supply and one emitter. The
Emitter should Light bright and solid. Repeat for all
emitters.
Use a diode tester to verify proper Emitter operation.
Remove Emitter from Connecting Block. Place the

Mono Mini Plug. Meter should read a voltage. When
he leads are reversed (Positive lead on Shield and
Negative lead on Tl P) you should not get any voltage
reading at all.
Remove the power supply from the connecting block
and all Emitters from the output. Place a jumper wire
on the connecting block between IR Signal and GND.
4.
Verify IR Receiver. Reconnect the Power Supply. With a known good
hand-held remote, shoot a constant IR Command at
the receiver and verify the TB LED on the Receiver
lights.
