Repeat step 8 until interference on all channels is eliminated.
NOTE: After changes have been made, the decoder must not
be switched off for at least 3 minutes to allow for the
new setting to be saved.
If interference is still present, it is recommended that good quality
screened cables (preferably double screened) are used for
interconnecting all other equipments to the decoder.
Adding a Modem
Many exciting interactive features will be available in the future (Impulse
Pay Per View, Video on Demand, etc.). The decoder is ready for these
features as it can accommodate an optional built-in modem. A modem
port for connection to your telephone line via an external (faster) modem
is provided on the rear panel.

that, for normal viewing, it remains connected to the mains after
