Delta 150 fsJICAM stereo TV tuner handbook
Set up switch
The set up/normal switch works in the same way as on a
VCR, and is used to provide a test signal which helps tune in your TV or
VCR to the remodulated output of the Delta 150.
When the Delta 150 is installed, switch the power on and
select the 'set up' position on this switch.
Select an unused channel on the TV (eg channel 5), and
adjust the TV tuning until the test signal appears
on the screen - two white vertical bars on a black
background. The television should be tuned in to
give the best picture, i.e. good definition on the
edges of the white bars, and uniform brightness in
the centre of the bars.
Test signal
Now select the 'normal' position on the set up switch, and
tune the Delta 150, as described on page 8.
It will probably be necessary to make this adjustment if you
use a satellite receiver as well as a VCR in conjunction with the Delta
150. In fact, it is possible that some re-adjustment of the channels
allocated to all these remodulated outputs may be necessary This is to
ensure that they do not interfere with each other or compromise the
reception of any TV transmissions broadcast within the range of
channels 30 to 39.
Power socket
Plug the supplied mains lead into the power socket, making
sure it is pushed firmly home.
ADJ
If the test signal cannot be obtained properly when tuning
your TV into the remodulated output of the Delta 150, then it may be
necessary to adjust this screw. This will alter the channel (i.e. frequency)
on which the test signal is transmitted. Insert a small screwdriver
through the hole in the back panel and carefully make small adjustments
(about '/20 of a turn at a time) until a clear picture is received. The range
of adjustment is from channels 30 to 39.
