Delta 150 NICAM stereo TV tuner handbook
Stereo LED
This LED (light emitting diode) will glow green when the
stereo flag is switched on at the transmitter. You may find that the stereo
LED will be illuminated even when a mono broadcast is transmitted. This
is not indicative of a fault, merely of the practice of the
broadcasting station.
LI, L2 Dual language mode LEDs.
The LI LED will glow green when a dual language
programme is transmitted. English is always transmitted as the main
language (LI j, and the second language is transmitted as L2.
The English language will be received automatically - there
is no need to select it. However, if you wish to receive the second
language, simply press the NICAM button once and the second
language will be received instead.
The L2 LED will now glow green.
Pressing the NICAM button a second time will return the
programme to L1. When a dual language programme is transmitted, the
stereo LED is not illuminated.
Note
When a dual language programme is transmitted, both
languages are in mono - although the chosen language will
automatically be heard through both loudspeakers of your TV or
hi fi system.
It is not possible to receive English on the left channel and
the second language on the right channel simultaneously.
Channel buttons
These two buttons select any of the 8 preset channels by
pressing the up Button to change sequentially from channels 1 to 8, and
the down button to change sequentially from channels 8 to 1.
NICAM button and LED
The NICAM LED uses a 'traffic light'sequence to indicate the
status of the sound track of the programme being transmitted.
If the LED glows red, only a mono FM programme is being
transmitted. This is automatically routed equally to both the left and
right audio outputs.
If the LED glows amber, a NICAM encoded programme is
being transmitted, but the tuner is switched to mono FM reception.
Press the NICAM button once and the LED will now glow green, to
indicate that the NICAM version of the transmission is being routed to
the audio outputs.
Press the NICAM button again to revert to the mono
FM mode.
Only if the LED glows green, are you receiving and listening
to a NICAM broadcast.
Tuning tip
When tuning in the channels of your Delta 150, please
observe the status of the NICAM LED.
If it glows amber, press the NICAM button before pressing
the store button, so that the NICAM LED now glows green.
This will ensure that every time this channel is selected, it will
be automatically received in NICAM (when transmitted).
Similarly, if a programme, which was originally available only
in mono FM (red LED), is now available in NICAM, you may find that
every time this programme is selected, the NICAM LED glows amber If
this is the case, simply press the NICAM button, so that the LED now
glows green, and then press the store button.
Power switch
This switches the unit on and off. The LED above the switch
will glow green when the unit is on.
