Dual Radar – Radar Overlay Control
Radar overlay for each radar channel may be switched on or off
independently.
The radar overlay icon on the upper toolbar displays the radar overlay
status from the two channel’s transceivers.
When channels 1 and 2 are in Transmit, and radar overlay is switched on
for both channels, the icon is displayed in the same way as described
previously for single radar.
To view the radar overlay status for each channel right click on the icon. If
both channels are in Transmit the option to select
Radar Overlay On or
Radar Overlay Off for both, or individually select radar overlay for channel
1 or channel 2 is available.
When only one channel is in Transmit the icon shows the number of the
transmitting channel (1or2). Right click on the icon in this mode only radar
overlay for the transmitting channel and Radar Overlay Off are available.
If radar overlay is switched off at channel 2 (with channel 2 still in
Transmit), or the video is automatically suppressed if channel 2 radar
overlay origin is too far from the centre of the display area, the video is
automatically switched back on if channel 1 is switched to or forced into
Standby, or the radar overlay at channel 1 is switched off.
If the origin of channel 2 radar overlay is automatically suppressed while
channel 1 is in Standby the video icon is displayed with a yellow
background and a temporary prompt appears confirming the video
suppression.
The yellow background is removed when either channel 2 radar overlay re-
appears, or channel 1 is switched to Transmit.
