Alignments FM24
Virgin
Normally 'off'. When this option is set to 'on', the display starts
with the language selection menu.
ICONN control
Normally 'off'. Set this option to 'on' in case a so-called
'ICONN'-box (for Hotel TV) is connected to the display.
Caution: When this option is set to 'on', without an ICONN-
Box connected to the monitor, one cannot control the monitor
anymore (because the RC connection is interrupted).
There are two ways to restore the remote control again:
• connect pin 8 (IR_TX) to pin 9 (IR_RX) on the RS232
connector of the monitor (the easiest way to do this, is to
make a 'dummy' connector with these pins connected, and
plug this into the monitor). or
• Set the set in the Service Alignment Mode (SAM) via
shorting jumpers 1 and 2 of connector 0382 on the
SCAVIO panel.
After this you can enter the appropriate menu to set
'ICONN control' to 'off' again.
