Switching On and Off
The receiver is switched on and off by
means of the toggle switch O situated on
the far left. Top position =

Loudspeaker Selection Switches
The toggle switches O allow to switch on
and off separately the two loudspeaker
groups. Top position on; bottom posi-
tion off.

FM Field Strength Indicator
The tuning meter of the set serves also as
field strength indicator.
This is particularly useful for the proper
orientation of a rotating multi-element
FM dipole. It is also possible to identify
the locally strongest FM transmitter
others, all transmitting the same pro-
gramme.
A properly orientated aerial —allowing
maximum field strength reception — also
reduces multi-path reception caused by
signal reflections.
The use of the field strength meter also
shows if any particular programme is
received with a sufficiently high signal
level. The high sensitivity of the set
ensures perfect reception for the majority
of transmitters, even if these only mar-
ginally exceed the ambient noise level. For
stereo transmissions, on the other
the aerial signal must be at least ten times
greater. Technical limitations

reason for this. The lower level for ade-
quate stereo receptions with this unit is
35 for a signal/noise ratio of 44.5 dB
(to DIN 45 500). At a lower field strength,
reception will become noisy.
