| Q - The picture for a particular
device is very dark/showing rainbow colored streaks/showing
ghosts.
A - You have a video over-modulation. Look at the
modulator that goes with that particular device and
see if the red light for Video Over Modulation is lit
up. If so, a service call needs to be placed.
Q - The picture for a particular device is not
coming through. I only see fuzz/snow.
A - Your modulator is not functioning properly.
Look at the modulator that goes with that particular
device and see if the green "Power" light
lit up. If not, a service call needs to be placed.
If the power light is on, make sure the device is on,
go back to the MENU, then reselect the device through
the system. This works for DVD players & other devices
which have an automatic shut-off feature that haven't
been used through the system for a while. If this does
not remedy the problem, you can try plugging in another
video device into the modulator. If you still do not
see a picture, place a service call.
If your school is operating under a WAN (Wide Area Network)
and the step above does not work, contact your district's
technology coordinator for assistance.
Q - The Audio/Video for a particular device is
flickering/intermitant.
A - Most likely, this is a wiring problem. Open
up the back of the rack and find the problematic device
(most racks should have labels identifying the devices
on the front and back of the devices). Every device
will have Audio Out and Video Out ports. Make sure these
connections are firm. Trace the cable down to its modulator
(which should also be labeled with the device's channel
number) and make sure the connections are firm there
as well. This will often fix the problem. If not, a
service call needs to be placed.
Q - Some of my VCRs are turning off by themselves.
A - Your VCR is set up in an automatic shut-off
mode (sometimes called "energysaver"). Get
your gray Headend Manual and find the manual for your
VCRs. Display the VCR on the TV in your rack. Using
the native VCR remote (not a SmartSystem® remote),
follow the instructions printed in the VCR manual to
set-up the VCR. Find the "energysaver" option
and turn it off. Exit out of the VCR programming menu
and you are done!
If you lose power to your building, you may have to
repeat this procedure again.
Q - When I put a video into my VCR, it automatically
starts playing.
A - Your VCR is set up in auto-play mode. Get your
gray Headend Manual and find the manual for your VCRs.
Display the VCR on the TV in your rack. Using the native
VCR remote (not a SmartSystem® remote), follow the
instructions printed in the VCR manual to set-up the
VCR. Find the auto-play option and turn it off. Exit
out of the VCR programming menu and you are done!
If you lose power to your building, you may have to
repeat this procedure again.
Q - Devices in a particular panel of the rack
are not responding to classroom remote control commands.
A - Find the Source Control Module (SCM) at the
top of the rack panel. Go around to the back of the
rack, find that SCM and press the tiny red RESET button.
Have teacher re-access the source and try to control
it again.
Q - Teachers say one particular device is not
responding to Remote Control commands, but they can
control other devices fine.
A - Check the front of that device in the rack to
make sure the IR Emitter is still attached to the IR
Sensor. If not, reattach and the device should immediately
start responding.
Q - Devices in a particular panel of the rack
are not responding to classroom remote control commands.
A - Find the Source Control Module (SCM) at the
top of the rack panel. Go around to the back of the
rack, find that SCM and press the tiny red RESET button.
Have teacher re-access the source and try to control
it again.
Q - The monitor in my rack does not have all
of the channels.
A - Find the remote which is the same brand as the
monitor (not your Dukane remote!), and reprogram the
monitor. Usually this can be done by accessing the "menu,"
followed by "autoprogram." This will begin
a search process for all of the available channels.
NOTE: For the monitor to recognize the live broadcast
cart channels, the LBC must be plugged in AND turned
on! This process may need to be repeated if there is
a power outage or a brownout. It is not necessary to
reprogram the tvs in the individual classrooms because
the channels which are set up for use are accessible
by using the remote to access the GLOBAL or AUX on the
main menu.
