Magnetically notched. When the control
is turned slowly, the bands are scanned
in steps of:
1 kHz on AM (LW, MW, SW), and
10 kHz on FM (VHP).
When the control is turned rapidly, the
‘sound is muted and the tuning steps
are increased as follows:
from +kHzto 3kHzonLW,
from 1kHzto 5 kHz on MW,
om 1 kHz to 10 or 100 KHz on SW,
ani
from 10 kHz to 100 kHz on FM.
@® Auxiliary Tuning Scale Drive and Fine
Tuning
The centre part of this control is a
switch which can be used to bring the
preselector and auxiliary tuning scale
@ into operation (the latter gives a
rough indication of frequency on AM).
When the switch is operated it does not
remain pressed in but returns to its
initial position so that it is flush with the
outer part of the control. When the
Preselector and tuning scale drive are
switched on, “AUT. PRESEL.” appears:
in the display ©. It can be switched off
by pressing the switch again, and
“AUT. PRESEL.” then disappears from
the display. This switch has no action
on VHF (FM).
The outer part of the control can be ro-
tated and provides fine tuning.
When the conirol is tumed, the
frequency reading in the display
does nat change as only the aerial in-
put and bandpass circuits are affected.
NB.
Because of the high power consumption it
is recommended that the auxiliary scale
drive is not used on AM bands (LW, MW,
SW) when the set is operated from
baiteries.

Power Supply
Battery Operation
The battery compartment @ and mains:
lead compartment @ are located behind
a sliding cover. Access to the battery com-
partment @ can be gained by sliding the
cover until the arrowhead on the cover is
opposite to the one marked BATT. This al-
fows the cover to be taken off completely.
Full access to the cable compartment ®
is obtained by sliding the cover fully to the
left, In this position the caver cannot be
removed.
When installing or replacing batteries in-
sert them as indicated by the symbols
{) in the battery compartment or holder.
The set is designed to operate from two
sets of batteries, Alkaline-manganese bat-
teries usually last longest and are highly
leakage-resistant.
@ Two HP 7 (IEC LR 6 or R 6) batteries or
equivalent for the clock and memory.
These batteries should always be
fitted even if the set is operated
from the mains.
When the set is switched off or if there
is a mains failure, these “standby” bat-
teries will supply the clock and memory
with power.
@ Six HP 2 (IEC LR 20 or R 20) batteries
or equivalent for radio operation,
When the set is operated from the
mains these batteries are automatically
disconnecied, Exhausted batteries
should be removed immediately from
‘the set.
If the set is not in use for long periods *
or is permanently operated from the
mains, the batteries for the radio sec-
tion should be removed from the set.
No responsibility can be accepted for
damage due to leaking batteries.
Note:
Alkatine-manganese batteries usually last
longest and are highly leakage-resistant.
B

GRUNDIG Dryfit Battery
In place of the six batteries for radio
operation you can install a GRUNDIG Dryfit
battery 476, This battery can always be re-
charged.
A single charging operation is sufficient to
operate the set on AM for about 21 hours
or on FM for about 20 hours. The battery
will be automatically charged when the set
is switched off but connected to the mains
supply or via socket @ to an external DC
supply of 12-16 V.
The charging time for a fully discharged
battery is approx. 15 hours.
The set is fitted with an automatic
charging circuit which prevents over-
charging. To achieve a long battery life,
never store it in a discharged condition.
* Battery Condition Indicator
With the switch @ in the upper position,
the meter ® indicates the radio battery
voltage or the condition of the re-
chargeable battery. If the pointer reaches
the green field of the meter @ (BATT./
ACCU), the batteries are satisfactory or
the rechargeable battery is charged. !f the
pointer does not reach the green field, the
batteries are exhausted and must be
changed or the rechargeable battery must
be charged.
This check is best done with the mains
cable disconnected.
Five horizontal lines and "BATT.” flashing
in the display ® with the set switched off
indicate that the standby batteries are ex-
hausted.
Before the standby batteries are replaced,
the six radio batteries or rechargeable bat-
tery must first be removed. The set should
be connected to the mains and be
switched on while these batteries are be-
ing replaced to ensure that the contents of
the memory and clock setting are retained.
Unless this is done, the time of day, date,
switch-on and off times and preset
stations will have to be entered in the me-
mory again.

Mains Operation
The built-in power supply unit enables the
set to be operated economically from
50-60 Hz mains and can be adjusted for
mains voliages of 110-127 and 220-240 V
{GB: 240 V AC).
The set must be disconnected from the
mains when the setting of the voltage se-
lector switch @ is changed. The set must
not be connected to the mains before this
has been done. Take out the mains lead
from the compartment @ and connect it to
socket @.
Additional Information for Sets Sold
in Great Britain
N.8. Ensure that the receiver is set for
220-240 V (GB: 240 V AC}.
We recommend that a 13 amp 3-pin
plug fitted with a 3 amp fuse be used.
The brown lead must be connected to
the live pin (marked "L” or ”red” or
brown”) and the blue lead to the neu-
tral pin (marked ”N” or “black” or
"blue"). On no account should either of
the wires be connected to the earth pin
(marked "E" or "green/yellow”). If other
mains plugs are used, ensure that they
are protected with a 3 amp fuse.
Changing Fuses
Unplug the set from the mains before
changing the fuses.
Open the fuse holder @ with a coin.
The fuse must only be replaced by one of
the same rating, ie: 315 mA time lag ("slow
blow’).
Waring
Never make improvised repairs to de-
fective fuses, as this may result in dam-
age to the set.
Operation from an External DC Source
The set will operate from an external
10-16 V DC source connected to socket @.
This facility is intended for use in cars,
boats or campers. Connection is with bat
tery adapter cable Il. Any batteries fitted
are automatically disconnected.
Aerials
®@ Telescopic aerial @ for receiving VHF/
FM and shortwave (SW) stations.
For FM reception the aerial should be
fully extended, then swivelled and rotat-
ed until best results are achieved. For
SW reception the telescopic aerial
should be vertical.
@ For optimum reception on all wave-
bands a 75 ohm external aerial may be
connected to socket @. (Switch from
telescopic aerial to external aerial by
releasing button @).
@ An external aerial and earth can be
connected to the clamping terminals @
for alt wavebands. Your dealer is
familiar with local reception conditions
and will be pleased to advise you on
the choice of aerial and its installation.
@ The set has a built-in ferrite rod aerial
for receiving mediumwave and long-
wave broadcasts.
The best position for receiving a station
should be found by rotating the set
about its vertical axis.
Radio
The set is switched on and off with
switch @.
=On
o= Of.
When the set is switched on and operated
from the mains, the meter @ and display
are permanently illuminated. When the
set is connected to the mains, out
switched off, the display @ is faintly illumi-
nated. The tuning scale @ is permanently
illuminated on the AM wavebands (LW,
MW, SW) when the set is operated from
the mains. When the set is operated from
batteries, the scale @, display @ and
meter @ can be illuminated for a short
period by moving switch @ ( ) to the
lower position.
The function switch @ switches the set on
and is on the secondary side. To isolate
the set completely from the mains, remove _
the mains plug from the wall socket.

Important
For normal radio reception on the AM
bands the operating mode switch @
should be set to 7AM” (centre position)
and the control @ (AM/RF GAIN
CONTR.) turned fully anticlockwise to
the AGC (lock-in) position.

Loudspeaker Switch ©
With 3 settings.
In the lower setting (qf 44), the built-in
broadband speaker and tweeter are in
operation. in the centre setting (q) the
tweeter is switched off, in the upper
setting (EXT.) both internal speakers are
disconnected and any extension
loudspeaker connected to socket @ is in
circuit.
It is thus possible with this switch to
select either the built-in loudspeaker or an
extension loudspeaker (if connected).
To improve the sound quality the tweeter
should normally be switched on when lis-
tening to FM, records or tape recordings.
On the AM bands it is advisable to use the
tweeter only for strong local stations and
with the bandwidth switch © set to "wide".
AM Bandwidth ©
On the AM bands (LW, MW, SW) the band-
width can be set to 3 different values with
switch @ (BANDWIDTH). In the left-hand
setting (1) the bandwidth is narrow. This
makes it possible to obtain better separa-
tion of two adjacent stations, ie: an inter~
fering adjacent station can be largely sup-
pressed. 7
In the centre setting ( [— |) the AM band-
width is increased to improve the sound
quality in cases where the “narrow” setting
need not be used, eg: particularly when a
fairly strong station is being received.
In the right-hand setting (f~ L) the AM
bandwidth is further increased; this can
be useful, for example, to obtain optimum
sound quality when a strong local station
is received.
In all three settings an interference filter is
in operation which is matched to the ap-
propriate AM bandwidth.
ANL Switch ©
If AM reception is accompanied by cracks
or clicks due to, eg: lightning discharges
or the switching of electrical appliances, it
is advisable to switch on the ANL (Auto~
matic Noise Limiter) (switch © in lower
setting). All noise peaks above the level of
the desired signal are then “clipped”. The
cut-off fevel is automatically adjusted to
the degree of modulation of the incoming
station.
When headphones are used, the ANL pro-
vides effective protection against damage
to your hearing. The ANL does not of
course give any improvement where the
frequency of the interierence is high
(crackle).
Aerial Trimmer ® <
This trimmer operates only on the short-
wave band when an external aerial is in
use (from about 15 MHz upwards). It can
also be used as an RF jevel control, since
it provides a reduction in aerial signal level
of up to approx. 15 dB. The trimmer does
not have any effect if the built-in telescop-
ic aerial @ is in use (switch from telescop-
ic to external aerial with the aeriat switch
@).
How to Use the Numbered Buttons @
These buttons are for keying in the infor-
mation required for direct frequency selec-
tion, setting the clock, selecting preset
stations etc., eg: time of day, date,
switching times, frequency and numbers
of preset station memories. To clear any
incorrect entries, press the button marked
CL (Clear) in this group. If a broadcast is
being received, the tuning does not alter
while entries are being made. The required
function will only be carried out when one
of the SET buttons @ is pressed.
Only entries keyed in correctly are ac-
cepted by the set. If entries are made in-
correctly, five "8s” will flash in the display
@ to indicate "incorrect operation”.

Important
Each programming step {entering the rel-
evant numerical information and pressing
the appropriate set button) must be car-
ried out not more than 30 seconds after
the preceding one, otherwise the new fig-
ures already entered will be lost and the
display will reveri to its previous reading.
NB.
Strong interference from, eg: badly sup-
pressed domestic appliances, may cause
the set to fail to accept entries because
the operation of the input processor has
been upset, with the result that the set
can no longer be operated.
In this case the receiver should be
switched off and the standby batteries
(two HP 7s) removed for about 1 min. (Re-
set).
After the batteries have been inserted
again, the ctock wit! start up after a short
period and the display will show” +0 0 ”
Then enter the time of day, date and
switching times again.
Tuning to Stations
1, Waveband Selection
The VHF, longwave, mediumwave and
shortwave bands can be selected with the
appropriate button (FM, LW, MW or SW) in
the group of buttons @®. Whenever a wave-
band is selected, the set immediately
tunes to the station last tuned to on the
band concerned. Other stations on the
band can then be tuned to manually, by
direct frequency input or by selecting pre-
set memory positions as described below.
2. The Preselector and Auxiliary Tuning
Scale Drive
These are operated by the control ®. The
centre part of the contro! is a switch and is
used to switch on the automatic preselec-
tor and the auxiliary tuning scale drive.
When these are switched on "AUT.
PRESEL.” appears in the display ®. They
can be switched off by pressing the
switch again, and when this is done, “AUT.
PRESEL.” disappears from the display ®.
The switch in control ® has no effect on
FM. When the automatic preselector and
the auxiliary tuning scale drive are in oper-
ation, the pointer of the scale @ will give
an approximate indication of frequency
when AM stations are tuned to manually,
by keying in the frequency with the num-
bered keys ®, or by selecting stations en-
tered in the memory (see Sec. 3, 4 and 5
below),
‘The outer part of the control ® can be ro-
tated and is used to adjust the preselector.
It does not change the frequency tuned to,
only the sensitivity.
N.B.
Because of the power consumption of the
motor, the use of the automatic preselec-
tor and auxiliary tuning scaie drive is not
recommended when the set is being op-
erated from batteries.
Note
The automatic preselector and auxiliary
tuning scale drive only provide approxi-
mate tuning. On SW especially, small
manual corrections will need to be made
by hand using the rotary part of the
control ®. lf the frequency is changed
with control ® after these adjustments
have been made the auxiliary tuning scale
drive will be activated and the preselector
may be brought back to a setting which is
not quite correct.
For this reason when small frequency
changes are being made, or a broadcast
band is being scanned or the set is being
used for SSB reception, the frequency
should first be tuned to with the automatic
preselector on, and after fine adjustments
have been made with the outer part of
control @, the preselector shouid be
switched off. Depending on the shortwave
band concerned, the frequency can be al-
tered by 50-200 kHz without any need io
adjust the preselector.
3. Manual Tuning
Once the required band has been select-
ed, stations can be tuned to manually with
the magnetically notched rotary tuning
control ®. Each notch alters the tuning by
1kHz in the case of AM (LW, MW, SW) and
by 10 kHz in the case of VHF/FM. The fre-
quency tuned to is shown in the display ®.
While stations are being tuned to, there
will be a certain amount of tuning noise.
This can be eliminated (muted) by turning
the tuning control more quickly. Under
these circumstances, the tuning steps will
aiso increase:
on LW from ikHzto 3 kHz,
on MW from 1kHzto 5 kHz,
on SW from 1 kHz to 10 or 100 kHz,
on FM from 10 kHz to 100 kHz.
This of course reduces the time required
to tune through rather large changes in
frequency. Once a station has been tuned
to, the outer part of the control @ should
be adjusted until a maximum reading is
obtained on the field-strength meter ®.
If required the automatic preselector and
auxiliary tuning scale drive can be used on
AM (see Sec. 2). The auxiliary tuning scale
@ will then give an approximate indication
of the frequency tuned to,
4. Direct Frequency Selection
The frequency of the station to be tuned to
must be known (frequency data may be
found in transmitter tables or local radio
programme guides). The frequency is.
entered with the numbered buttons @
{see also section entitied "How to Use the
Numbered Buttons”).
4.1 Selecting AM (LW, MW, SW)
Stations
‘The frequency is always shown in MHz in
the display ®.
if a single figure, eg: 6, is entered in the
SW band, it will be identified as 6 MHz and
6.000 will apear in the display ®. To enter,
say, 6.075 MHz in the SW band, key in
6075 with the group of buttons @ and
then press the FREQ. bution @ (6.075 will
then appear in the display).

In the SW band it is not therefore
necessary to key in the decimal point with
the "@" button in the group of buttons @.
We recommend that frequencies in the
MW and LW bands be entered in MHz
inserting the decimal point with the "@”
button @.
Examples:
To enter 200 kHz in the LW band,
key in "0.2":
To enter 720 kHz in the MW band,
key in "0.72";
To enter 1248 kHz in the MW band,
key in "1.248".
In all cases the FREQ. bution @ must be
pressed after keying in the frequency to
complete the tuning operation.
The automatic preselector and auxiliary
tuning scale drive can of cours be
switched on and used when selecting sta-
tions by direct frequency selection on the
AM bands.
4.2 Selecting FM (VHF) Stations
In this case the decimal point @ must be
entered as well.
Example: Selecting 88.90 MHz
1. Press FM waveband button ®.
The station tuned to on this band be-
fore the set was switched off will be
heard.

5, Automatic Selection of Stations
The set is equipped with a memory in
which the frequencies of up to 60 stations
can be entered in numbered positions.
Once the frequency of a given station has
been entered in the memory it is possible
to tune to it instantly by selecting the ap-
propriate band, keying in the number allot-
ted to the station with the group of buttons.
@, and then pressing the STATION
RECALL button @.
The number of stations which can be en-
tered in the memory varies from band fo
band as follows:
LW: 4 stations
{buttons 1-4 @ used for selection)
Mw: 8 stations
(buttons 1-8 @ used for selection)
FM: $16 stations
{all buttons @ can be used for
selection)
SW: 32'stations
{all buttons @ can be used for
selection).
W

N.B,
Remember that whenever a band Is se-
jected with the group of buttons ®, the
last station tuned to in the band will be
heard.
Example:
a. FM Stations
Suppose you wish to enter a VHF station
broadcasting on 97.90 MHz on memory
position "1” for the VHF (FM) band. First
tune to the station manually or by direct
frequency selection (see Sec. 2 and 3
above).
Now key in the number of the memory po-
sition (in this case "1”) to which the station
is to be allocated and press the "STORE
STATION” button ®,
The siation is then entered in the memory
and can be selected at any time using the
automatic selection system. At this point
the display @ will show
To select @ (VHF) FM station entered in the
memory, select the VHF band with the FM
button (group of buttons @), press button
"1" @ and then the STATION RECALL
button @.
b. AM Stations
AM stations are entered in the memory in
exactly the same way and later selected
as described above. In this case, however,
the automatic preselector and the motor
drive for the auxiliary tuning scale can be
used if desired (press the centre part of
the control @) (see Sec. 2 above).
"AUT.PRESEL.” will then appear in the dis-
play ©. When this drive system is on and
AM stations entered in the memory are se-
lected, the auxiliary tuning scale pointer
will give an approximate indication of fre-
quency. The display ® will show the pre-
cise frequency, the waveband (FM) and
the station memory position number as
well as "AUT. PRESEL.”.
The auxiliary tuning scale @ is only for
use on AM, and in addition to indicating
frequency gives the centre frequency of
SW and amateur bands (eg: 11.8 MHz is.
marked above the 25-m band as the
centre frequency).
Clock Operation
The maximum 30 second interval between
each programming step also applies to the
clock. The time of day, the date and the
switching times can be entered even with
the set switched off. When the time is dis-
played, it is shown in hours and minutes
with the seconds reading in small figures
underneath.
Setting the Clock to the Time of Day
Example: The time of day (eg: 6.30) can
be entered using the numbered buttons @
in any the following ways:
"630", "6.30", "0630", "06.30".
tt is not therefore essential to enter the
decimal point. The clock will start running
exactly from the minute displayed (ie: sec-
onds reading "00") as soon as the SET-
TIME button @ is pressed. The time can
be displayed when the display is showing,
eg: frequency, by pressing button @
(TIME). When the set is switched off, the
display always shows the time of day.
Setting the Date
The date (eg: 9.7) can be entered using
the numbered buttons @ in any of the
following ways:
"09.07" or “09.07.” (the decimal point must
be entered after the day, but is not es-
sential after the month).
If the number of the day or month is jess
than 10, it should be preceded by a ”0”
(eg: January = 01).
The date is entered in the memory by
pressing the DATE bution @ and will ap-
pear in the display © for 30 seconds.
When the set is switched on the date can
be displayed for 30 seconds by pressing
the DATE bution @, after which the dis-
play will revert to the frequency. The dis-
play can be switched to frequency imme-
diately by pressing the FREQ, button @.
If the set is switched off and the DATE but-
ton is pressed, the display will show the
date for 30 sec. and then automatically re-
vert to the time of day. The display can be
switched to showing the time of day im-
mediately by pressing the TIME button @.
Programming the Switching Times
The set can be programmed to switch on
and off automatically at preset times up to
three times a day. The switching times are
entered in the memory by means of the
ON-TIME and OFF-TIME SET buttons @).
The ON-TIME/OFF-TIME RECALL butions
@ are for displaying the switching times
once entered.
Example: Switch-on time 16.00 hours.
First select the switch-on time memory po-
sition by pressing the ON-TIME RECALL
button @). If a switch-on time has already
been programmed, it will appear in the
display ®. If not, the display will show a
colon with two lines to the right and left of
it. Enter the required switch-on time using
the numbered buttons @ (1-6-0-0) and
enter it in the memory by pressing the ON-
TIME SET button @. The second and third
switch-on time memory positions can then
be selected with the ON-TIME RECALL
button @ and further switch-on times
entered in the memory by repeating the
above procedure.
A similar procedure is followed for the
three swiich-off times except that the
OFF-TIME RECALL button @ is pressed to
select the switch-off time memory position
and the OFF-TIME SET button @ to enter
the time in the memory,

The switch-on and -off times can also be
programmed in alternately. This need not
be done in chronological order. The clock
processor will automaticatly arrange the
switching times in chronological order, If
the display is switched to another function
(date, time or frequency) not more than 30
seconds after the last programming entry.
Switching times already in the memory
can be replaced by new ones. If a switch-
ing time is to be retained, one of the two
remaining sets of switching memory posi-
tions ("on” and “off” times) must be se-
lected by pressing the RECALL. ON-TIME
or OFF-TIME button a second time.
Setting the Radio to Switch On
Automatically
If the set is to switch on automatically with
a station tuned in (eg: as an alarm), press
one of the waveband buttons LW, MW, SW
or FM @ and tune io a station which will
be broadcasting at the switch-on time.
Then set the function switch @ to the top _
position (AUT,). The set will now switch on
at the preset time (ON-TIME) tuned to the
station received tast in the waveband
selected.
The set will switch off automatically at the
preset switch-off time (OFF-TIME).
If you have a portable GRUNDIG cassette
recorder you can also record radio broad-
» casts on tape in your absence, To do this,
connect the universal 8-pin socket on the
cassette recorder to the tape socket
{ 200 @) on the Satellit with the cable
STK 227. Select record and start on the
cassette recorder. When the Saitellit
switches on automatically, the cassette
recorder will start recording.
With record/standby selected on the
recorder it is advisable to connect it to the
mains (to reduce battery usage).
The SSB Section
The three controls and switches ©, @, ®
belong to the SSB section and have the
following functions:
Conirot @ AM RF GAIN CONTR. :
The AGC (Automatic Gain Control) is
switched on when this control is turned
fully anticlockwise (switching position).
MGC (Manual Gain Control) comes into
operation and the gain can be varied when
the control is turned clockwise. Switch ®
MODE (LSB, AM, USB) is for selecting the
operating mode. Control @ BFO/SSB-
CLARIFY is used for fine tuning SSB trans-
missions.
Important
The SSB unit should be switched off for
normal reception on AM wavebands, Set
the contro} @ to AGC and switch @ to AM,
otherwise distortion and whistle may occur.
Reception of SSB Stations
In normal radio transmissions the carrier
and two matching sidebands are transmit-
ted. Such stations can be tuned to without
difficulty. Tuning is more complicated in
the case of the SSB (single-sideband)
transmission system, used mainly by radio
amaieurs. Only one sideband is transmit-
ted in this case; the carrier and the other
sideband are suppressed. Moreover, this
single sideband is only present when the
SSB transmitter is modulated (usually by
speech), ie: tuning is not possible during
the pauses.
For SSB reception it is important to tune
the receiver with the manual control ®
and the CLARIFY control @ in such a way
that the sideband being received and the
carrier generated in the set match each
other very accurately.
We recommend the foliowing procedure
(example : tuning to SSB transmissions in
40 m amateur band (7.0-7.1 MHz): initially
the SSB unit is not in operation and the
CLARIFY acontrol @ is set to its centre po-
sition. Tune the set to 7.0 MHz and set the
preselector ® to its optimum position,
then switch off the motor-driven tuning
system (if selected) (press contro! ® to
release it). Then scan the band for ama-
teur stations by slowly turning the manual
iuning control @. When a station is found
(usually between 7.050 and 7.100 MHz),
adjust the mannual control for maximum
deflection of the pointer of the meter ®,
which swings in step with the as yet
unintelligible speech.
Then select MGC with switch @ and ad~
just the control so that reading of the
meter ® ts below "5". For weak stations ft
may be necessary to tum it fully clock-
wise, Next switch the MODE switch @ to
LSB. It is then usually possible to re-
cognise that speech is being broadcast,
although it may still be difficult to under-
stand. Intelligibility can then be improved
by turning the CLARIFY control @ slowly
clockwise or anticlockwise. If the speech
is still unclear, increase or reduce the fre-
quency by 1 kHz with the manual controt
and then adjust the CLARIFY control @
again until the speech is intelligible. This
may be necessary particularly for weak
stations, because the optimum tuning
point cannot be found or is difficult to find,
It should always be possible to obtain in-
telligible speech, If the frequency of the
SSB station is known it can of course be
entered with the numbered keys @ ; this
greatly simplifies the tuning procedure.
Finally it should be noted that the lower
sideband (LSB) is transmitted in the 80
and 40m amateur bands and the upper
sideband (USB) in the 20 and 15 m
amateur bands.
