At power-up this welcome screen is displayed. Main SW and user interface SW version numbers plus unit
serial number are shown.
When the unit is powered the display lights up showing selected output channels (Fig 1. no 2 ). The factory
set output channel is E21.
The display is switched off after 3 minutes. Two signal led indicate that the unit is powered. The display
lights up again by pressing any button of remote controller unit.
Next program info for channel previously selected is displayed and the channel opened, if possible. Info
shows program name, transponder frequency, channel video and audio PID number.
3.2 First time set-up
When using the unit for the first time, you must first connect video and audio connectors to monitor. After
this you can continue set-up using on-screen menus.
To control the unit first slide front panel switch to “ON”. When programming is ready, the front panel
switch must be slide to “OFF”. This will prevent accidental changes to be made while controlling other
