8Putting the receiver into operation
The receiver is switched on with the ON / OFF switch . Display panel is now lit up to show
that the receiver is switched on, and the last frequency set is shown (see chapter 10). The display
OMUTEO (see chapter 13) is lit up . If a suitable transmitter is already operating on this frequency,
the display OMUTEO is initially lit up for about 4 seconds. Then the display changes to ORFO and
ODEVO - (RF level and modulation, see chapter 13), and the diversity branch in use is displayed
(see chapter 4).
Note
The ON / OFF switch works in the secondary circuit of the integrated mains
transformer, and thus only switches the low voltage side. By using a modern magnetic
core transformer, the power consumption of a EM 3031/3032 receiver of approx.
1
/2 Watt when switched off is extremely low. For larger installations with several
receivers, a complete mains disconnection can best be achieved by an additional
common ON / OFF switch.
The AF connection is via the socket on the rear. The control
controls the AF signal
output level.
