12 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,
disconnect power from the machine and reconnect again to
reset the machine.

2. If the following recommended actions still do not result in

satisfactory operation, please consult your KRAMER Dealer.

12.1 Power and Indicators

Problem Remedy
No Power

1. For

the

SD-7108, SD-7208, SD-7816 and SD-7816B, confirm that the

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

2. For

the

SD-7108, SD-7208, SD-7816 and SD-7816B, 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. 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.

3. For

the

6104 – check for proper DC polarity, and if needed, carefully

remove the cover of the machine and check the on-board fuse. Replace
the fuse with an identical-value fuse if necessary.

12.2 SDI and Digital Audio Signals

Problem Remedy
No video or audio at
the output device.

1. Confirm that your source and output devices are turned on and connected

properly. The input of your machine should be of an identical signal
format or standard as the output of your source. Signals at the output of
your machine should be of an identical signal format or standard as at the
input of your display or acceptor.

2. Confirm that any other device in the signal path has the proper input

and/or output selected.

3. Confirm that the maximum cable length was not exceeded.

Disappearance of the SDI or the Digital Audio signals may be a result of
the “cliff effect”.
