2) Using arrow keys, move the menu to the channel concerned and press key OK.
3) Using arrow keys, scroll the several configurations and press key OK.
4) Press key ESC to go back to the previous menu.
5) Repeat point 2 to change another channel.
The several channels: Ch. 1, Ch. 2, Mpx 1 and Mpx 2, when enabled, must be assigned
the priority. The channel with higher priority must be assigned number 1; accordingly,
the others will have priorities 2, 3, or 4.
It is impossible to assign two channels the same priority.
5.3 Times and Levels: "Var" Menu
Menu Var is made up of the following menus: start up time, analog off time, switch
off time, restore time, analog low level and analog high level.
5.3.1 Start-Up Time
The start-up time is enabled every time that Discovery is switched off. During such
periods, no exchange move is operated. We advise you not to set this time for a
period less than 15-20 seconds. The ideal condition is to set this period 2-3 seconds
longer than the PLL synchronisation of the transmitting apparatus.
During the start-up phase, the keyboard is disabled and the display visualises
possible programmed text lines or the words "R.V.R. Elettronica".
5.3.2 Analog Off time
This parameter is associated with analog level. When a signal maintains under
the preset threshold in the "analog low level" field or exceeds the "Analog High
level" threshold for a period of time equal to or higher than the Analog Off Time,
the Discovery changes over the audio signals to the following channel defined in
the menu of priorities.
If the S/N control is enabled by means of the jumper, the off time is the same as
the time relevant to the analogue signals.
