TAKING CARE OF 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 switcher where 
temperature and humidity may be excessive. Doing so may also damage the electronics, and cause 
erratic operation or failure of your switcher. Do not clean your switcher 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. 
 

10. 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. 

 

10.1 

Power and Indicators 

Problem Remedy 

 

No power 

1. 

Confirm that the rocker switch is in the “ON” position, and that it is 
illuminated. 

2. 

Confirm that power connections are secured at the machine and at the 
receptacle. Make sure the receptacle is active, outputting the proper 
mains voltage. 

3. 

If there is still no power, check the fuse. Remove the power supply from 
the AC outlet and from the machine and then remove the cover of the 
VS-3000 and locate the internal fuse. Confirm that the fuse is good by 
looking at the wire connected to the ends of the fuse. If the wire is 
broken, replace the fuse with another of the same value and replace the 
cover of the machine. 

 

10.2 

HUM and Electric Interference 

Problem Remedy 

 

Noise bars “roll” up 
or down in the output 
image 

or:  

Low frequency hum 
in the output signal 

 

 

Hum bars (ground loop) are caused by a difference in the ground potential 
of any two or more devices connected to your signal path. This difference is 
compensated by passing that voltage difference through any available 
interconnection, including your video cables.  

WARNING

Do not disconnect the ground from any piece 
of video equipment in your signal path!  

Check the following to remove hum bars: 

1. 

Confirm that all interconnected equipment is connected to the same 
phase of power, if possible. 

2. 

Remove equipment connected to that phase that may introduce noise, 
such as motors, generators, etc. 

3. 

Disconnect all interconnect cables and reconnect them one at a time until 
the ground loop reappears. Disconnect the affected cable and replace, or 
insert an isolation transformer in the signal path.
