and turn up the receiver's gain until only one
LED lights. For rooms with high ceilings,
multi-transducer clusters, or highly
reverberant conditions, it may be necessary to
attach the receive unit to a piece of conduit
or broomstick to obtain proper proximity to the
source.
5. A speaker that is in proper polarity (positive
signal moves cone away from magnet) will light
the green LED.
6. An out of polarity speaker will light the red
LED.
V. What does all this mean?
A. Balanced device polarity:
1. An intact properly polarized device will light
the green LED in the 2-T position and the red
LED in the 3-R position.
2. If there is a dead short between any two
conductors, neither LED will light.
3. If #2/tip and #3/ring are reversed the red LED
will light in the 2-T position and the green
LED will light in the 3-R position.
4. Any other combinations of LED's lit, or the
presence of hum when the device is in use,
indicate opens or reversals that warrant visual
inspection, repair, and re-testing.
NOTE: Proper and reverse polarity of #2/tip and
#3/ring will be indicated whether #1/shield is intact
or not when tests are performed with the "CON/POL"
switch in the "POL" position.
