Particularities on AM
Preselector
When receiving AM stations, the input and intermediate circuits of
the receiver can be tuned in two different ways:
1) Automatically with motor drive. In this case "AUT. PRESEL." will
appear in the display @.
The automatic fine tuning with the motor drive can be switched
on and off with the inner part of control @) (press button).
2) Manually with the knob@) (outer part of control@) which can be
rotated).
When this operating mode is used, it must be differentiated
between:
optimizing the recpetion when the motor drive is in opera-
tion
-
manual fine tuning with switched off motor drive.
You should use the automatic fine tuning with the motor drive in
the following cases:
-
generally when receiving on the LW band
-
generally when changing the wave band
-
in the MW and SW bands when
a) you are tuning to the stations rapidly
b) you are entering the frequencies with the numeric buttons
@
c) you call stored stations with the numeric buttons@.
After having performed these operations, you may optimize recep-
tion by manual fine tuning (outer rotating part of control @)).
You should switch off the automatic motor drive in the following
cases:
- when receiving MW or SW stations, especially on SSB recep-
tion, when you are tuning through the waveband in small steps.
-
on battery operation to save battery life (because of the consi-
derable power consumption of the motor).
When using the preselector, the scale@) will give an approximate
indication of the frequency tuned to. In addition, scale@) will de-
liver informations about the centre frequencies of the individual ra-
dio or amateur wave bands (e.g. 11.8 MHz on the 25m radio
band).
ANL Switch®
•
ANL on = switch
®
in bottom position.
The ANL circuit (automatic noise limiter) limits irregular interfe-
rences which may be caused by lightning discharges, switching
functions of electrical appliances, etc.)
The cut-off level is automatically adjusted to the degree of modu-
lation of the incoming station.
When you are using a headphone, the ANL circuit provides an ef-
fective protection against damage to your hearing.
Of course, the ANL circuit will not give any improvement in the
case of high frequency interferences (crackle).
AM Bandwidth ®
e
On the AM bands (LW, MW, SW) the band width can be set to
three different values.
In all three settings an interference filter is in operation which is
matched to the respective AM bandwidth.
SL...
= narrow.
In this position it is possible to se-
parate two closely adjacent stations.
...rL...
=broad.
In this setting the AM bandwidth is in-
creased to improve the sound quality when receiving fairly strong
stations.
..r-----L
= super broad.
In this position of the switch,
the AM bandwidth is further increased. This can be useful to ob-
tain optimum sound quality when a strong local station is received.
Storing of Stations
The receiver is provided with a memory in which up to 60 stations
can be entered and stored. The number of stations which can be
stored in the memory varies from band to band as follows:
4
stations on the LW band
8 stations on the MW band
16 stations on the FM (VHF) band and
32 stations on the SW band.
Each station you are listening to at the moment can be stored:
•
Enter the number of the memory position to which you want to
allocate the station with the numeric keyboard @.
e
Depress the SET key @ STORE STATION.
The display@ now additionally indicates STAT and the number
of the memory location. The stored station can still be
heard.
Recalling Stored Stations
•
Select the desired waveband with button® (LW, MW, SW, FM).
•
Enter the number of the memory location to which you want to
allocate the station with the numeric keyboard @.
•
Press the station recall button @ STATION.
-
If the called memory location is not yet allocated to a station,
the set is automatically tuned to the lower cut-off frequency of
the selected wave ban de (e.g. 510kHz on MW).
- When receiving on the AM wavebands, the automatic motor
drive should be switched on. The outer rotating part of the Pre-
selector control @)then permits to optimize the quality of re-
ception (fine tuning).
Setting the Clock and the Date
The maximum 30 seconds interval between each programming
step also applies when setting the clock and the date.
Entering of the data is possible in several ways, e.g. with or without
decimal point, with three or four digits, etc. In the following, only
the simpliest way of entering the data is shown. If any particularity
must be oberserved, this will be indicated.
The time of day, the date and the switching times can be entered
even when the set is switched off.
Setting the Clock to the Time of Day
Example: 6.30 hours:
•
Subsequently enter the figures 6 3 0 with the numeric key-
board@.
When the reference clock changes form 6.29.59 to 6.30.00
e
press the set button ®TIME and the clock starts running.
Indication of the Time of Day
When the set is switched off, the time of day is permanently indi-
cated,
When the set is switched on and with button AUX. ® being de-
pressed, the time of day is also permanently indicated.
With the set switched on and with radio reception, the time indica-
tion can be switched on and off as follows:
e
Press the display button @ TIME.
The time is displayed instead of the frequency.
To return to frequency indication
•
press the display button @ FREQU. or
•
turn the tuning control knob @.
Setting the Date
For setting the date, the German way of writing is used, i.e. day -
month.
Please note two particularities:
- A point must be entered after the day.
-
Day and month must be entered with two digits each.
Example: July, 9:
•
Subsequently enter 09.07 with the numeric key board @.
e
Press the date set button
®
DATE to store the date .
Now the date will be indicated in the display@ for about 30 se-
conds.
Recalling the Date
Independent from the indication in the display@, the date can be
recalled at any desired time.
•
Press the date display button @ DATE.
The date will be indicated in the display for 30 seconds.
It is also possible to immediately switch over to another indication,
e.g.:
to indication of the time of the day. To do so
•
press the time display button @ TIME.
Frequency indication:
•
press the frequency display button @ FREQ.
or another waveband button ®
or turn the tuning knob @.
