Loudspeakers
To achieve the best results we
that you choose GRUNDIG HiFi Loud-
speaker Enclosures as these are of the
highest quality and capable of handling
the full output power of the unit.
The loudspeaker impedance must be 4 Q
to obtain full power output and the
impedance must never be allowed
below 3.2 Q. It is permissible, however,
to use loudspeakers with an impedance of
up to 16 Q provided that the loss of output
power experienced is tolerable.
On the rear of the set, connecting sockets
for two separate stereo loudspeaker
groups are provided (pos. O. O). These
speaker groups can be operated
simultaneously in two separate rooms
(black sockets = stereo group I, green
sockets stereo group II).
Loudspeaker group I or II, used for stereo
reproduction, will deliver 2 x 50 W nominal
power (2 x 70 W music power). For two
room stereo (groups I -F 2), the power
output will be 4 x 15 W nominal
music power).
Always make sure that the right-hand
loudspeaker unit is connected
socket and vice versa.
Note: Loudspeaker extension cables are
available in 5 metres length (cable 375a)
and 10 metres length (cable 376a).
Headphones
For those ardent music lovers,
wish to disturb others and who, themselves,
do not wish to be disturbed, connecting
sockets O for two pairs Of stereo
headphones are provided (DIN 45 327).
We recommend headphones with an
impedance between 5 and 2000 Q, in
particular GRUNDIG HiFi Headphones 2i6
or 223.
Switching On and Off
The receiver is swit&ted on and off by
means of the toggle switch O situated on

Automatic FrequencyControl on FM (AFC)
The automatic frequency control is in
operation when the toggle switch O is in
its top position. It locks in a station once
it is tuned in. When tuning in a different
FM station switch off the AFC by setting
the AFC switch O to its bottom position.

FM Programme Keys
The keys O can be programmed to
store 7 different FM stations. The stored
stations can be recalled instantly by
lightly pressing the required key.
The tuning controls are to be found behind
the flap above the keys. To facilitate
tuning, use the bushing inside the flap. To
tune in the individual stations proceed as
follows:
Switch off the AFC by setting switch O
to its bottom position.
Slightly press the required key.
Fit bushing onto corresponding tuning
control (U I ... U 7) and tune in
desired station. When tuning refer to
the frequency meter @ which will
display the frequency of the station
being received. Final tuning should be
made by referring to the tuning
meter O. Always tune for maximum
deflection on the meter. The
"Tunoscope" @ is an additional
tuning aid on FM — see corresponding
paragraph.
When all the desired stations
stored the AFC should be switched
again. It will ensure correct tuning when
a station is recalled.
Aerial Rotator
The Receiver is fitted with a rear mounted
socket O for connection to the
"programmatic-rotor" aerial rotator
manufactured by Stolle & Co.
The position of the aerial rotator can be
programmed when the VHF stations
being tuned.
When a station is recalled by pressing
one of the FM keys the VHF dipole will
automatically be steered towards the
transmitter.
FM "Tunoscope"
The three light emitting diodes O permit
easy and accurate tuning of FM stations.
For this first switch off the AFC.
tune in the desired FM stations so that only
the middle green LED lights up. The
left or right red LED will light up if the
station is not accurately tuned in. If both
red LEDs are lighting, only a very weak
station or no signal at all is received.
Switch on the AFC again after having
tuned in the station.
