Note: Use only Quattro LNBs. If optical splitting is required, use PLC splitters.
Optical multiswitch:
•
Connect input SC/APC socket to other optical device (splitter, transmitter)
•
Connect output F sockets with user wall sockets or directly with satellite receivers*
•
Connect DC2.1 socket marked “DC 12V” with power supply unit – it is included in the package
•
Connect connector marked with protective bounding symbol with protective bounding conductor
* RF signals applied to transmitter’s inputs appear at multiswitch’s outputs

The maximum signal level of the optical transmitter’s inputs should not exceed 85-90dBuV, there is a
significant deterioration in signal quality at higher levels.
It is recommended to add terrestrial TV preamplifier at the terrestrial input of the transmitter.
The wiring examples are shown in the section 9) Wiring Diagrams or at the website www.emp-centauri.cz.
6) Safety
Due to security reasons the product and wiring in which the product is connected, must be grounded
properly. Make sure the antennas are grounded properly. Connect all devices to power grid only after all
connections are finished and checked. Never work on the wiring (including satellite receivers, TVs) during
or before a storm. A lightning stroke into the antenna may cause dangerous overvoltage in the product
metallic parts.
7) Product Maintenance
Always disconnect the product from the power supply and coaxial wiring before performing any
maintenance of the product.
If you have to enter places with a risk of fall, pay attention to your safety. Use
only dry cloth to clean the product and do not use any liquid agents.
8) Symbols Explanation
certificate of conformity
Protective ground
Invisible laser radiation
According to EU directive, electric and electronic devices which are identified by one of the
following symbols must not be disposed of together with municipal waste. When disposing of
the old device, use local waste collection and separation systems.
