squares forming on the
screen or sometimes the
picture freezes Could be caused by low TV signal
strength or poor quality reception To check the signal level use the information
plate as described on page 9. If the signal
strength % is black in colour you will have

Why does the show guide
(EPG) show some digital
TV stations but I can not
receive them Some of the digital TV stations are
transmitted in high definition (HD).
This set top receives standard
definition (SD) TV stations only and
will not display HD stations If you want to pick up HD TV stations you will
require a HD set top box
Why does the television
set top box not have all
channels tuned It is possible that the signal level for
a TV channel might have been low
for some reason during the tuning
process Repeat the setup procedure for tuning in TV
stations
Why does the picture on
the TV look green It is possible that the red video
RCA lead and the red audio RCA
lead on the back of the TV may be
connected incorrectly Change around the two red RCA leads on
the back of the TV
