Friendly Robotics robomower RL350 Service Manual page 151

5.3.3 Set Country
It used for positioning the Robomow globally. This operation is important, as the
Robomow needs to be able to adjust the sensitivity of the magnetic navigation system to its
location on the globe. This process should be done only once, prior to the first automatic
operation. This is a preliminary step to DK Calibration. DK Calibration will not succeed
without first setting the country location.
5.3.4 DK Calibration
The DK (Direction Keeping) calibration calibrates the Robomow to the magnetic fields in
the customer's yard.
A. Enter DK Calibration in the 'Service' menu.
B. Verify that Set Country is already set at the correct country for use.
C. Insure the Robomow is positioned on a leveled and smooth surface inside the perimeter
wire. It should not be placed close to anything that could alter the earth's magnetic field
such as buried or overhead power lines, large metal objects or concrete floors with steel
reinforcing bars for example.
D. Turn the Perimeter switch on and perform the DK Calibration as shown in the sequence
below:
Test passed
Press C
When calibration is completed a
'Test passed' will be displayed.

If the calibration was not successful

The mower will now rotate 2-4
turns. Wait until calibration is
completed.
