[Premium-Rx] Telettra HF-L-R Scanning Receiver - looking for manuals

[Sergio Sigala]

Dear Sirs,

Finally I got my first, real, premium rx!

It's a Telettra HF-L-R Scanning Receiver (see below for details).
Views of various Telettra HF-L-R receivers operating can be
found there:

The Telettra are the five receivers at the bottom of the following picture:

The following image is a detail of the previous:

Now I'm looking for the operation and maintenance manuals.
Somebody has them ?

Best regards,

Telettra HF-L-R Scanning Receiver
---------------------------------

The HF-L-R can be used as either a communication or search and
intercept receiver and covers the 50 kHz to 30 MHz frequency range
in 10 Hz steps. It has two independent microprocessor modules and
is suitable for use either in a stand-alone configuration, or as a
basic building block for a computer-controller HF network.

The receiver operates in AM, CW, SSB and FM modes.  An internal FSK
demodulator and an ISB module are available as options.

An input attenuator is automatically inserted when the input signal
level exceeds the range of linearity. Sub-octave filters
automatically preset, increase the rejection of unwanted signals
and avoid the receiver blocking.

The receiver has a module capable of storing up to 99 channels.  For
each channel, the most important parameters of the receiver
operating condition can be stored in a non-volatile memory.

The operator can read or write into the memory without
interrupting the receiver operation.

Three options are available: local-, extended-, and remote-control.
The receiver can be remotely controlled in every operational
function, including diagnosis (up to failed module) and the
read/write operation.

Status: in service and hundreds of units sold since 1986.  Used in
Spider intercept/direction finding system.
