Never work on the wiring including satellite and terrestrial receivers, TVs) during or before a storm. A
lightning stroke into the antenna may cause dangerous overvoltage in the product metallic parts.
The product should be disconnected from the wiring immediately if it gets into contact with liquids dropping
water, spilled drinks etc.).
8) Product Maintenance
Always disconnect the product from the power grid and 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.
Coaxial cables installed outdoors should be replaced once in a few years. Unscrew all F connectors and
clean connector contacts, resp. shorten the coaxial cable by approx. 2 cm, every 2 years.
Check the state of power supply and its mains cord periodically. If the mains cord or the mains plug of
product is damaged, it must be replaced by manufacturer or qualified technician to prevent any dangerous
situation. Let the product serviced if the housing of power supply is damaged.
If not used for long time, disconnect the product from the power grid.
9) Troubleshooting
Always disconnect the product from the power grid before working on product, otherwise you risk the
electric hazard. Pay attention to your safety if you have to enter places with a risk of fall.
In the case the product does not work and LED of power supply is on:
•Check if the terrestrial and satellite antennas are correctly fixed, optimally set and connected to
the product, satellite and terrestrial receivers turned on, plugged on and correctly set.
•Check the connector connections. The inner conductor of coaxial cable must be in contact with
the inner conductor of F socket and the shielding of coaxial cable with F connector. Replace
broken or interrupted coaxial cable.
•Sometimes the reset of the multiswitch microprocessor is enough to fix the problem. Pull out the
power plug of the multiswitch and satellite receiver from power grid and then re-plug them a few
seconds later.
In the case the product does not work and LED of power supply is off or blinks:
•Check that the product is connected to the power grid with AC voltage. If not, connect the product
to the power grid with correct AC voltage.
•Disconnect the product from the power grid and check that there is no short-circuit on the input
satellite coaxial cables, which prevents the power supplying of LNBs. If yes, remove short-circuit
and re-plug the product into the power grid again.
•The power supply can fail temporarily in case of overload or overheating. The cause can be
current consumption of devices connected to the satellite inputs of product which exceeds the
specifications, see section 2) Product Specifications. The next cause can be the overheating of
product in consequence of wrong installation, see section 4) Product Storing and Installation.
Disconnect the product from the power grid, remove the cause, and re-plug the product into the
power grid after a few minutes again.
t the failure seems to be not related to power supply, check setting of all satellite receivers
connected to SCR output. Wrongly set up receiver may disturb or disable the operation for all other
users that share the same cable.
If the failure cannot be removed, please contact your distributor.
