DIRECTIONS FOR USE
INITIAL SETrINGS
Turn on the receiver on the AF GAIN
(12)
or on the power supply N1400 or
N1401
and turn the AF GAIN
(12)
to approx. middle position.
Turn the CLARIFIER (15) to the center position, the RF GAIN (13) fully clock-
wise and the AGC SWITCH (14) to position ON. Choose the wanted mode of recep-
tion on the MODE SWITCH
(II).
(For further description of mode filter - and AGC
selection, please examine the paragraphs below).
FREQUENCY CONTROL
The frequency is controlled from the KEYBOARD
(I)
and the CONTINUOUS TUNING (10)
wheel. The wanted frequency must be entered into the KEYBOARD
(1)
in kHz and
l
is then displayed on the liquid crystal DISPLAY (5). The decimal point is only
to be used when a fractional kHz is wanted. After- entering a frequency the re-
ceiver is blocked and the CONTINUOUS TUNING
(10)
wheel is disabled.
After keying in a frequency you must press the NOISE GENERATOR (4) and adjust
RF TUNE (7) for maximum reading on the METER (6). For frequencies below 150 kHz
chosen there is no tuning to be done on the RF TUNE (7), just press NOISE GENE-
RATOR (4) to unblock the receiver.
,P
Now the wanted frequency is selected and the receiver front end is tuned. The
s
CLARIFIER (15) controls the frequency between the
100
Hz steps selectable.
>
For searching over a frequency range the CONTINUOUS TUNING
(10)
wheel is acti-
vated by pressing the decimal point key on the KEYBOARD
(1).
When the desired
s
frequency is found the CONTINUOUS TUNING
(10)
wheel can be disabled by pres-
sing the zero key on the KEYBOARD (I).
The CONTINUOUS TUNING (IO) wheel is able to tune the receiver over the full
frequency range
10
kHz to 30 MHz. It is necessary to follow the frequency tu-
ning wheel with the front end tuning on the RF TUNE (7). Each time you pass a
band limit by means of the CONTINUOUS TUNING
(10)
the receiver blocks. (Band-
limits: 150 kHz, 530 kHz, 1.6 MHz, 4 MHz,
7
MHz,
14 MHz and 30 MHz). To unblock
the receiver again you must press the NOISE GENERATOR (4) and adjust the RF-
0
TUNE (7) for maximum METER (6) reading.
DISTRESS
With the controls set as described under INITIAL SETTINGS above just turn the
MODE SWITCH
(II)
to DISTRESS
(2182
kHz.1 position.
Now the receiver is ready
for reception on the distress frequency, mode selection (AM) and front end tu-
ning is automatically done in the receiver.
SSB TELEPHONY
For normal telephony purpose turn the MODE SWITCH
(II)
to A3J (SSB) position.
Now SSB reception of normal upper sideband is established.
For SSB telephony purpose the preferable AGC
(14)
position is ON.
