SCM Doing the soundcheck (EM 500 only)
By doing a soundcheck you can check the reception area for field strength
gaps (“dropouts”) which cannot be compensated for by the EM 500’s diversity
circuitry. The EM 500 enables you to do the soundcheck without the help of
another person.

Make sure that the corresponding transmitter is switched off.

You can now check the results of the soundcheck on the receiver. If
the “
MUTE ” display is lit up, “dropouts” have occured. The bargraph
displays will indicate the lowest RF and the highest AF level. The
displays “
I ” and “ II ” indicate that both receiver sections are active.

If “dropouts” have occured, you now have to find out where exactly
the reception is subject to interference.
If only one receiver section is indicated, check the antenna connections.

button. “ REPEAT ” appears on the display. Repo-
sition the antennas and press the SET button. The soundcheck starts
over again and the previously measured data are then deleted.
To terminate the soundcheck, press the button. “ END ” appears on
the display.

then switches back to the standard display.
