14.TAKING CARE OF YOUR MATRIX
Do not locate your matrix 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.
15.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.
15.1Power and Indicators
Problem | Remedy | |
|
|
|
No power | 1. | Confirm that the rocker switch is in the “ON” position, and that the lamp |
|
| is illuminated. |
| 2. | Confirm that power connections are secured at the amplifier 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 power cord from the |
|
| AC outlet and from the machine and then, using a flat head screwdriver, |
|
| remove the fuse holder located directly below the power connector. |
|
| 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. |
15.2 Video Signal
Problem | Remedy | |
|
|
|
No video at the output | 1. | Confirm that your sources and output device are powered on and |
device, regardless of |
| connected properly. Video signals connected to the input of your |
input selected. |
| switcher should be of an identical signal format at the output of your |
|
| source. Video signals at the output of your switcher should be of an |
|
| identical signal format as at the input of your display or recorder. |
| 2. | Confirm that any other switchers in the signal path have the proper input |
|
| and/or output selected. |
| 3. | Use the Video Tester to test the video path leading to/from your switcher |
|
| (see section 4.1 " Video Tester") |
|
|
|
Video level is too high | 1. | Verify that the video line is well matched through 75ohm impedance, |
or too dim. |
| otherwise it results in a video level that is too high or too dim when |
|
| looping is performed and the termination switches are not in proper |
|
| position. |
| 2. | Confirm that the connecting cables are of high quality, properly built and |
|
| terminated with 75ohm BNC connectors. Check level controls located on |
|
| your source input device or output display or recorder. |
