Step 5: Testing the System
Step 1:
After the 95 kHz carrier cable, power
cables, and audio source are connected,
turn the MOD 1 power switch on. The
green LED on the front of the MOD 1
should light.
Step 2:
Make sure the sound system is on and your
audio source is active. Adjust the Audio
Level control on the front of the MOD 1
until the “OK” light flashes with the audio
signal. It is okay if the red “Hi” light
flashes occasionally, but it should not stay
lit constantly. If you can't get the “Ok”
light to come on, make sure the Input
Level switch is set properly. If it is, you
need to boost the signal source.
Step 3:
Look at the transmitter panel(s). With the
modulation signal and power connected, a
red light should be visible in the center of
the panel.
Step 4:
Hold a receiver near the “Infrared Test
Out” hole on the front of the MOD 1. Turn
the receiver on and adjust the volume. You
should be able to hear the audio signal
through the receiver. If not, make sure the
audio “Ok” light is still flashing. If the
light is not flashing, check your audio
source or the setting of the input level
switch and input level control. If the audio
light is flashing, but you don’t hear
anything from the receiver, try a different
receiver to make sure the receiver is
working.
Step 5:
Take a receiver into the listening area and
walk around to check the reception. Make
sure the “eye” on the receiver is not
covered up when in use. The receiver will
not work if it is placed in a pocket or
purse. The receiver eye must be able to
“see” the transmitter panel. It may be
necessary to adjust the angle of the
transmitter(s) to obtain the best coverage.
If coverage is not adequate, additional
transmitter panels must be used.
