1) Disconnect any signal from the external stereo-encoder input and any RDS or SCA signal.
2) Select the display menu field "MPX" and check the pilot tone, which must be now the only signal avalable.
The standard level is that previously stated, i.e. 9-10% or -21 ÷ -20dB, and may be adjusted accordingly
on the external stereo-encoder to suit the request.
3) Reconnect any previously disconnected signal as done.
Very low power level transmission:
SIRIO2000T transmitter is not reccomended as a very low power unit. Do not use at less than 250W
, never below 100 Watt. Although rare, with specific power and frequency combinations (usually at less
than 20 Watt), some sub-harmonic and/or spurious signals may be generated, and the power level stability
is anyway not good as it is at higher power level. Moreover, it may be dangerous to use a transmitter which
may generate a very higher power if improperly set in a lower power tailored antenna/filters environment.
If low power level transmission is imperative, adjust it very carefully and also pre-set the maximum
output power which may be adjusted by main regulation: the software permits to adjust the max RF output
level (cfr. relevant section in the manual). Carefully check with a spectrum analyser that the transmitter is
workly properly at and just below the operating power.
The installation of the transmitter is thereby completed. Many other monitoring and control facilities are
provided by the internal display and software, and are remotely accessible. Navigation through the menu
driven software is suggested and encouraged to gain confidence with the options: no extensive training is
needed for the most common options. Neverthless some options are hidden for security purposes and
always require the password. Read the relevant section of the manual to know all possible functions which
are adjustable.
AEV S.P.A. reminds you that we are always available for further informations or to tackle any specific
problem You may encounter.
OPERATION WITHOUT THE ANTENNA OR WITH A FAULTY ANTENNA
CONNECTION MAY CAUSE DEGRADATION AND POSSIBLE DESTRUCTION OF THE
FINAL STAGE. THIS FAILURE IS NOT COVERED BY THE GUARANTEE.
