1 GENERAL
1.1 Description
The EN-106 is a module able to generate a signal in DVB-T format
(Digital Terrestrial Television) from an audio / video (A/V) analogue input.
The audio / video analogue input has three RCA sockets, one for
VIDEO signal and two more for RIGHT and LEFT audio signal.
These two analogue signals are processed through a MPEG-2
compression system, that digitises and compresses them, obtaining then a
MPEG-2 transport stream, which is digitally modulated in order to obtain a
multiplex, with a television service, at the DVB-T output socket.
This DVB-T signal can be inserted via the RF input (for loop-through)
into an already existing television distribution network, with the advantages
of robustness and high quality that digital technology offers.
The EN-106 module adjusts the compression rate to the available
bandwidth, using the modulation DVB-T parameters.

2.2 Maintenance
2.2.1 Cleaning Recommendations
CAUTION
To clean the cover, make sure the instrument is disconnected.
CAUTION
Do not use scented hydrocarbons or chlorized solvents. Such products may
damage the plastics used in the construction of the cover.
The cover should be cleaned by means of a light solution of detergent and
water applied with a soft cloth.
Dry thoroughly before using the system again.
CAUTION
