PRODUCT DESСRIPTION
TV modulator MT41 is intended to form TV channels of G/K/I/L/H/M/N/Australia standards in UHF ranges.
TV modulator MT47 is intended to form TV channels of B/G/D/K/I/L/M/N/Australia standards in VHF and UHF ranges.
TV modulator MT57 is intended to form TV channels of B/G/Australia MONO/STEREO A2 and D/K/I/L/M/N MONO standards in
VHF and UHF ranges.
Broadcasting signal has double sideband modulation.
The modulators are intended for indoor use only.
SAFETY INSTRUCTIONS
Installation of the modulator must be done according IEC60728-11 and national safety standards.
The modulator is powered from mains 230V~. This voltage is dangerous to life.
Any repairs must be done by a skilled personnel.
To avoid the electric shock follow these instructions:
do not remove the cover of the power supply section, without disconnecting the unit from the mains supply;
do not plug the modulator into the mains supply if the power cord or plug are damaged;
do not plug the modulator into the mains supply until all cables have been connected correctly;
to disconnect the modulator from mains completely, disconnect plug from mains socket;
the mains socket must be easily accessible;
modulator shall not be exposed to dripping or splashing water and no objects filled with liquids, such as vases, shall be placed on it;
avoid placing modulator next to central heating components, near highly compustible materials and in areas of high humidity;
before connecting the modulator to multimedia system, be sure that system is installed in accordance to national safety standards;
devices of multimedia system should have easy access to disconnect them from the mains supply;
no naked flame sources, such as lighted candles, should be placed on modulator;
if the modulator has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before plugging into
the mains;
do not insert any objects into ventilation openings;
the ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths, curtains;
mount the modulator on not flammable wall or in not flammable installation box in vertical position with power supply located on
the left. The modulator must be fixed with steel screws Ø 3.5-4 mm. The screws are not included in a package;
from top, front and bottom of installed modulator must be at least 10 cm free space.
Caution (mark on rear side).
Risk of electric shock (mark on rear side).
This product complies with the relevant clauses of the European Directive 2002/96/EC. The unit must be recycled
or discarded according to applicable local and national regulations (mark on rear side) .
Equipment intended for indoor usage only (mark on rear side).
Apparatus is double insulated from the mains.
This product is in accordance to following norms of EU: EMC norm EN50083-2, safety norm EN62368-1 and RoHS
norm EN50581.
This product is in accordance with Custom Union Technical Regulations: "Electromagnetic compatibility of technical
equipment" CU TR 020/2011, "On safety of low-voltage equipment" CU TR 004/2011.
This product is in accordance with safety standard AS/NZS 60065 and EMC standards of Australia.
