TAKING CARE OF YOUR MACHINE
Do not locate your machine in an environment where it is susceptible to dust or moisture. Both of these may
damage the electronics, and cause erratic operation or failure. Do not locate your machine where temperature
and humidity may be excessive. Doing so may also damage the electronics, and cause erratic operation or
failure of your machine. Do not clean your machine with abrasives or strong cleaners. Doing so may remove or
damage the finish, or may allow moisture to build up. Take care not to allow dust or particles to build up inside
unused or open connectors.

TROUBLESHOOTING
NOTES
1. Please note that if the output signal is disturbed or interrupted
by very strong external electromagnetic interference, it should
return and stabilize when such interference ends. If not, turn
the power switch off and on again to reset the machine.
2. If the following recommended actions still do not result in
satisfactory operation, please consult your KRAMER Dealer.
11.1 Power and Indicators
Problem Remedy
No Power
1. Confirm that the rocker switch is in the “ON” position, and that the switch is
illuminated.
2. Confirm that power connections are secured at the machine and at the receptacle.
Make sure the mains receptacle is active. If still there is no power, remove power
cord from AC outlet and then, using a flat head screwdriver, remove the fuse
holder located directly below the power connector on your machine.
3. Confirm that the fuse is good by looking for the wire connected between the ends
of the fuse. If the wire is broken, replace the fuse with another, with the same
rating.
11.2 Video Signal
Problem Remedy
No video at the output
device
1. Confirm that your source and output devices are powered on and connected
properly. The input of your machine (parent picture) should be of an identical
signal format at the output of your source. Signals at the output of your machine
should be of an identical signal format as at the input of your display.
2. Confirm that any other device in the signal path has the proper input and/or
output selected.
3. Use the Video Tester to test the video path leading to/from your machine (see
section 4.1 " Video Tester").
Video level is too high
or too dim.
1. Verify that the lines are well matched through 75ohm impedances, otherwise the
video level will be too high or too dim.
2. Confirm that the connecting cables are of high quality and properly inserted.
