Symptom #7:
 Absolutely No Functionality (How to determine which component is at fault)
Step: Component to Test Instructions
1. 
Verify Power Supply 
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 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.) 
2. 
Verify Emitter. (283M or 286M Blink
Style ONLY) 
Remove the power supply from the 
connecting block and all Emitters from 
the output. Place a jumper wire on the 
connecting block between IR and +12v. 
Reconnect the Power Supply and one 
emitter. The Emitter should Light bright 
and solid. Repeat for all emitters. 
3. 
Verify Emitter. (282M or 284M NON 
Blink Style) 
Use a diode tester to verify proper 
Emitter operation. Remove Emitter from 
Connecting Block. Place the Positive 
Lead of the tester on the TIP of the 
Mono Mini Plug and the Negative Lead 
on the Shield of the Mono Mini Plug. 
Meter should read a voltage. When the 
leads are reversed (Positive lead on 
Shield and Negative lead on TIP) you 
should not get any voltage reading at all.
