Safety Instructions
WARNING: To prevent re or electrical shock, do not expose the device to rain
General Precautions
Avoid placing the device next to central heating components and in areas of
high humidity.
Do not cover the device with elements that obstruct the ventilation slots.
If the encoder modulator has been kept in cold conditions for a long time,
keep it in a warm room minimum 2 hours before plugging into the mains.
Mount the encoder modulator in vertical position with the connectors
located on the top side.
When replacement parts are required, be sure the service technician has
used replacement parts speci ed by the manufacturer or have the same
characteristics as the original part. Unauthorized substitutes may result in
re, electric shock or other hazards.
Safety check- Upon completion of any service or repairs to this device, ask
the service technician to perform safety checks to determine that the device
is in proper condition.
Power precautions
The encoder modulator is powered with a voltage of 12V DC. The power
supply voltage must not exceed the recommended voltage, which otherwise
may cause irreparable damage to the device and the invalidation of the
warranty. Therefore:
- Do not replace power supply with a voltage greater than 12V DC.
- Do not connect the device to the power if the power cord is damaged.
- Do not plug the device into mains supply until all cables have been
- Do not cut the cord.
or moisture.

554902 encoder & modulator (home use) is Televes´ consumer product which
allows audio/video signal input in TV distributions with applications in home
entertainment, surveillance control, inns, restaurants, small shops, etc.
It is a device that allows to convert a composite video signal (with or without
audio) into digital DVB-T COFDM signal and so distribute for the existing
network.
The signals source could be from satellite receivers, CCTV cameras, DVD players,
etc. Its output signal is to be received by a DVB-T standard TV, DVB-T STB etc.
With this DVB-T modulator is also possible to use a USB memory as signal
source.

Connect the signal source, select “Start Record” and choose “Yes” to start
recording.
Advanced Con g:
File size: User can set the le size for the *.ts to be recorded. A single le
can be maximum 2000MB in size.
File save mode: there are three diferent modes:
- Single le (For example, when the le size is set as 1000M and the *.ts is
recorded up to 1000M, it automatically stops recording TS.).
- Segmented le (For example, when the le size is set as 1000M and the *.ts
is recorded up to 1000M, it automatically saves the les and continues to
record TS and save it to next le until the USB memory is full.).
- Loop record: (it automatically saves the les and continues to record
TS and save it to next le. When the USB memory is full, it replaces the
previous les.)
File name: User can edit the name for the *.ts les to be recorded. For
example, if users name it “Record-”, it will give name to the saved *.ts
les“Record-001.ts”, “Record-002.ts”…“Record-00N.ts”.
Automatic Record: User can choose between record the TS automatically
or manually.

information (Network ID, Network Name, LCD Mode, Private Data and LCN
number of the program mentioned in explanation 6) will be added to the
transport stream.
- NOTE: when the Private Data is set as 0*0, it is invalid. For example in UK is
necessary to edit the value of Private Data to: 0x233A.
