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.

NOTES

 

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.   
If the following recommended actions do not result in satisfactory operation, please 
consult your KRAMER Dealer. 
 

11.1 

Power and Indicators 

Problem Remedy 

No Power 

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

If there is still no power use a Philips screwdriver to 
remove screws on both sides of the machine and release 
the panel. 

Locate the fuse inside your machine. Confirm that the 
fuse is good by looking for the wire connected between 
the ends of the fuse. If this wire is broken, replace fuse 
with another, with the same rating.  

Install cover and tighten the Philips screws.
