walks forward naturally for several meters after turning on the tilt compensation
function. You can start tilt survey right after you walk to the survey point.
There are two methods to turn on or off tilt compensation. One is turning on or

is through Nuwa app. After the Oscar GNSS receiver Ultimate version is

interface.
When tilt function is turned on, the tilt LED on the Oscar Ultimate OLED display
lights on with steady red, a few seconds later it starts flashing red. At this time,
walk a few steps ahead, tilt the pole at any direction, then the tilt LED turns
steady green which indicates tilt compensation is valid. Now you can start tilt
survey.
When the tilt compensation is valid, click the Satellite info icon to view the

The tilt status is displayed at the top of the survey interface. When the tilt

ensure that the antenna height setting is correct which will affect the tilt
measurement results.
