The ‘english’ selection is the default. This is known as MPEG stereo sound and is available at all times for Standard Definition broadcasts.

The ‘english5.1’ option is available when either an (1) optical TOSLINK cable or (2) coaxial cable is connected between the set-top box and a Digital Surround Sound Amplifier.

Troubleshooting: Although the set-top box will indicate 5.1 sound, most programmes however are 2/0 surround sound.

SWITCHING LETTERBOX 4:3 MODE

If you have a standard 4:3 ‘square screen’ type television, you can enjoy the widescreen view (whilst in the ‘info’ mode) by pressing the blue key. Black bars will appear across the top and bottom of your television screen. This is normal. Note that this option only appears when ‘4:3 television’ is selected in the Video & Audio preferences.

Notice: In this mode you may see white dots on the top or bottom of the screen for some programs. These dots are broadcast related and cannot be removed by the set-top box.

TURN-OFF INFO MODE

Simply press the key again or press the cancel key on the remote controller to exit the ‘info’ mode.
