User manual
NOTE: Sometimes the transmitted service
does not identify the audio language
correctly (for instance, it sends '---'
instead of an audio identifier such as
'eng'), so the receiver cannot iden-
tify the selected language. Should
this happens, it is recommended to
use the manual mode to select the
audio.
In audio for index the user selects the audio
service from the list of available audios for
the present program:
- Audio for index:
The corresponding audio subcarrier willl be
modulated (L+R)/2.
R will be modulated in the audio subcarrier.
L will be modulated in the audio subcarrier.
NOTA: If the service of audio is dual mono
(a language in the channel L and
another one in channel R), the user
it will have to select the suitable
option (Right or Left). If Stereo is
selected will leave both languages,
each one in its channel.
To carry out the modification the
must be pressed until the desired parame-
ter flashes. Then the correspondent field can
be modified using the and
e.- Monitor menu 1
This menu shows the following information:
estimation of the BER (bit error rate before
Viterbi) and the firmware version of the
MPEG decoder.

f.- Monitor menu 2
This menu indicates current temperature on
a 1-10 scale, as well as the maximum tem-
perature recorded at any time by the equip-
ment. By pressing the key, the maximum is
reset and updated according to current tem-
perature.
The recommended operation ranges are as
key
follows:
Optimal function: 0-6
High temperature: 7-8
keys.
Excessive temperature: 9-10
In the event that the maximum recorded lies
outside the optimum range, the installation
should be altered to bring down temperatu-
re. Should the modules be in a Ref 5069
cabinet installed and the working tempera-
ture be over the optimal level, the installation
of a ventilation unit Ref 5334 is strongly
recommended. To check whether this chan-
ge has been successful, you can reset the
maximum and check temperature value
after a certain time.
