5. First steps
5.1 Front panel operation, manual tuning
Attention: Read safety informations page 2 very carefully. Before connecting receiver to mains,
select mains voltage and fuse-current on the rear pannel voltage selector/fuse holder.
Attention:
The receiver can have a built in IEEE - interface. Front panel operation is only possible if
the rear switch is in the off-position. This switch is off if the "red eye" is invisible.
A) Set all switches to the position marked by the hand-symbol in the picture on this page.
Switch 2.2 in the left position, turn 2.3 until 60 dB
µ
V is reached as attenuator reading.
Set the A.F.- volume in half position.
B) Switch on the receiver by pushing (9).
C) About 1 second after switching on a pulse is heard. The meter reading approaches
centre (0 dB) and then returns to the left end of the scale. This was the automatic
priority calibration with 100 Hz pulses according to band B 150 kHz.
The receiver is now ready to use and frequency is tuned by rotating the encoder (5.2).
The steps can be selected with (5.3) fine or coarse.
Fine permits narrow band signals to be tuned easily. Coarse is ideal for broad pulse
spectrums, and frequency hopping.
For overviews it is ideal to choose Log. indication with Low Noise (4) and reading the
upper meter scale (1).
If the frequency is tuned with the encoder (5.1) from 00.150 MHz (150 kHz band B) in
direction to lower frequencies, the receiver switches to band A at 00.100 MHz (100 kHz),
to give to the user an information below the frequency limit (info).
Then follows the change to band A and the frequency display changes to 150.00kHz.
The right lowest significant digit is then 10 Hz! If the frequency is increased, the frequency
changes to 00.150 MHz / band B.
In the right corner of the frequency display (5.3) the upper or lower segment shows band
A or B.
After this change between band A/B a recalibration is good practice (3).
