Problems and solutions
There is no picture on the TV
– Check the HDMI or SCART cable connections of the Horizon box
and TV.
– Check the cable connection between the Horizon box and the wall
socket.
There is no sound on the TV
– Check the HDMI or SCART cable connection between the Horizon
box and TV. If other audio devices are connected, check their cables
also.
– Verify that the volume level is not set to zero.
There is no power supply to the Horizon box
– Check if the power supply cable is correctly plugged into the Horizon
box and the mains socket.
– Check that the ON/OFF switch on the rear of the Horizon box is set
to the ON position.
The Horizon remote control no longer works, the Horizon box
does not react to its commands
If the remote control no longer functions correctly, it is probably time
to replace the batteries. If the remote control still doesn’t work
after having replaced the batteries please call UPC customer
service (0800 66 88 66) to have your remote control replaced.
The volume controls on the Horizon remote control do not work.
I
can’t change the volume for any programmes
To increase or decrease the volume for digital television programmes,
the remote control must rst be set up for use with your television.
Otherwise the sound volume can only be adjusted using the TV remote
control.
For more information, refer to pairing the horizon remote control
with your tv.
The television picture is pixelated (“blocky” effect)
The signal received by the Horizon box is too weak. Check the coax cable
between the wall socket and the Horizon box. In order to ensure the
quality of the digital signal, you must use the cables supplied (see p.
7) or C12-compatible cables. C12 stands for Coax12; this cable cor-
responds to the special requirements for damping and radiation. If you
have your own distributors or ampliers, always connect them exter-
nally – the Horizon box must be directly connected to the wall socket.
If the picture remains pixelated after the cables have been checked,
please call customer service on 0800 66 88 66.
