8) Product Maintenance
Always disconnect the product from the power grid and wiring before performing any maintenance of the
product.
Use only dry cloth to clean the product and do not use any liquid agents.

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
