Standby
This stops transmission, but keeps the radar ready to transmit again.
Off
This saves on power consumption (but you must turn it on and wait for the radar to warm
up before you can use it again).
The radar transmits until you change the radar mode to Standby or Off.
Set Radar Range offset (trigger delay)
The radar sweep should commence at your vessel (a radar range of zero). You may need to
adjust the radar range offset to achieve this. (The radar range offset is also known as the
trigger delay.)
If this is set incorrectly, a large dark circle in the center of the sweep might occur. You might
notice straight objects such as straight sea walls or piers having curves or an indentation.
Objects close to your vessel may appear "pulled in" or "pushed out". To rectify this, adjust the
radar range offset using either the straight line or the circle method.
To adjust the radar range offset using the straight line method:
Position the vessel about 45 m to 100 m (50 yards to 100 yards) from a straight-walled jetty
•
or similar feature that produces a straight line echo on the display.
• Select the 1/8 mile range.
Adjust the gain setting until a reasonably good image of the jetty echo is displayed.
•
Adjust the radar range offset to make the jetty echo appear as a straight line on the display,

To adjust the radar range offset using the circle method:
If it is not possible to position the vessel near a suitable target, perform a rough set up of the
range offset by using the circle at the center of the radar screen as a guide.
