Calibrating the Altimeter
Because the Rino 530 relies on the barometric pressure
to determine the elevation and the pressure at any given
elevation can fluctuate, you can calibrate the altimeter
to increase its accuracy. You must know the elevation
(from a map point or other reliable data) or the pressure
(calibrated to sea level - information you can obtain from
the NOAA weather forecasts received on your Rino 530
or other reliable source) for your current location.
To manually calibrate the altimeter:
1. Use the Thumb Stick to access the Option Menu.
2. Highlight the Calibrate Altimeter option and press
the Thumb Stick to display the Calibration Page.
3. At the message asking “Do You Know The Correct
Elevation?” highlight the on-screen Yes button and
press the Thumb Stick In to enter your elevation.
When finished, highlight OK and press it In to
return to the Altimeter Page. If you don’t know
your current elevation, press No to move to the
pressure calibration page.
At the message asking “Do You Know The Correct
Pressure?” highlight the on-screen Yes button and
press the Thumb Stick In to enter your pressure.
When finished, highlight OK and press it In to
return to the Altimeter Page.
Programming Data Fields
Two, user-selectable, data fields support this page and can
be programmed to display the data options.
To program a data field:
1. Use the Thumb Stick to highlight the desired data
field and then press it In to select desired data
from the options list.
