The SLxRF modulator works by using an unused UHF channel on your TV to show
the signal from your AV equipment. On your TV, each terrestrial TV channel
occupies a UHF frequency. In the UK, a typical example of the fequencies used for
each channel are:
On the rear of the SLxRF modulator is a 8-way DIP switch (just below 'CHANNEL
SETTING'. By selecting the OFF (up) or ON (down) position of each of the 8
switches, you can choose any UHF channel between 21 and 69 (471.25 to
855.25MHz) for the the SLxRF modulator to display the desired AV signal.
To avoid inteference between channels, there must be a
3-channel UHF spacing
between each channel. E.g. do not set up your DVD player on channel 40 and your
satellite on channel 41. The following settings are suggested as a guide :

B. Setting the output frequency (continued)
For the SLxRF modulator to
work, it must be set to use a
UHF channel that is not already
used by a TV channel, or the
VCR if it is connected to your TV
by a RF flylead (the coaxial
input).
