ON AIR PROTECTION

Summa's 'on air protection system' provides three modes of operation:
• On
• Rehearse
• Off
When 'on air protection' is switched on or into rehearse , certain talkback and tone options are disabled to help to avoid
unwanted broadcast of tone and talkback feeds. The tone and talkback settings associated with the three operation
modes are shown in the table below.

Changing Modes

With the touch display interface in 'active Show' view , the 'on air' mode selection button is in notifications area along
the top of the screen. Tap the 'on air' button to and select one of the three mode options from the pop-up.

On Air Mode via GPI

Two GPIO options are available relating to the 'on air protection' system: 'On air protection - on' and 'on-air protection
- 'rehearse'. Applying a signal to either of these GPIs puts the console into the on or rehearse mode.
If mode selections are made both by GPI and from the touch display interface, the highest setting will be used:
On being the highest and Off the lowest.
