Troubleshooting

A. No picture appears on the TV or projector.
1) Check that all cords are plugged in, especially the power cord, and that the TV or
projector is on.
2) Check that the power switch on the scope's cradle is on (the red light will be illuminated).
3) Press the LIGHT/ON button on the scope to make sure the lights are on.
4) Check that the correct channel or input is selected in your display. See the table below
for some tips:
Step 1
Television Plug the video cable into a yellow video
input port (this could be on the front or
the back of the TV).
Projector Plug the video cable into the yellow
video input port (located on the back or
side of the projector)
DVD/VCR If you have a DVD or VCR hooked up to
your TV, you can have the SOAR go
through it (so you don't have to unplug
it from the TV). Plug the video cable
into a yellow video input port on the
DVD/VCR (this could be on the front or
the back).
White Board Plug the video cable into the yellow
video input port.
Computer Plug the video cable into the yellow
video input port on a digital converter.
Plug the converter's USB cable into
your computer.
B. Image produced by the 1X lens is a weird color.
1) For the "New" SOAR, turn the scope off, then back on, using the power switch on the
cradle. This should correct the color balance. If that does not help, press the LIGHT
button to return to the previous setting.
2) For the "Old" SOAR, press the ERASE button located on the underside of the scope. If
that does not help, press the ON button to return to the previous setting.

Step 2
Depending on the type of TV you have,
you will have to do one of the following:
• go to the channel below 2
• press the input button on the remote
until you see "AV, video, or composite"
• go to the menu and select the input
source to be one of the above choices
The projector might find the correct input
on its own, but if not, press the input
button and select "composite video."
Make sure the TV is on the right channel
to view the DVD/VCR. Then either press
channel down on the DVD/VCR until you
get to a channel below 2 (AV, video, etc.)
or go to the DVD/VCR menu and select
the proper input.
There are many different brands of active
board. You may need to consult the
manual for your instrument or contact the
school/district technology specialist.
You have to install the software first.
Refer to the software instructions if
necessary.
