Important safety instructions

General installation conditions
• Read these instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions.
• Do not use this apparatus near water.
• Clean only with a dry cloth.
• Do not block any ventilation openings. Install in accordance with the manufacturer's
instructions.
• Do not install near any heat sources such as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce heat.
• Only use attachments/accessories specified by the manufacturer.
• Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer,
or sold with the apparatus. When a cart is used, use caution when moving the cart/
apparatus combination to avoid injury from tip-over.
• Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, liquid has been spilled or objects have fallen
into the apparatus, the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.
Warning
Apparatus shall not be exposed to dripping or splashing and no objects filled with
liquids, such as glasses, shall be placed on the apparatus.
Safe installation
Do not place the equipment near heat sources or in a highly humid environment.
Do not place the equipment in a place where it can suffer vibrations or shocks.
Please allow air circulation around the equipment.
Do not place naked flames, such as lighted candles on or near the product.

* The unit's consumption with CAM will depend on the type of CAM being used (only ref. 563301).
For the LNB it is considered a standard consumption of 300 mA.
The technical characteristics described are defined for a maximum ambient temperature of 45°C (113ºF). Forced ventilation is used for higher temperatures.

Programmer / PC connector
The DVBS2 transmodulator with COFDM CI receives a satellite transponder
in some DVBS (QPSK) or DVBS2 (QPSK or 8PSK) modulation formats and
demodulates it by obtaining an MPEG-2 transport package.
The MPEG2 transport package is then modulated in COFDM format and
converted to the output channel (UHF or VHF and with a maximum
bandwidth of 8 MHz) using an agile up-converter.
Additionally, ref. 563301 incorporates a Common Interface slot for inserting
a conditional access module (CAM) to permit the unscrambling of services.
The programming of the transmodulator operating parameters (input
frequency, output channel, modulation format and adaptation of services
mainly) is performed through the universal programmer (ref. 7234).
