Dear all,
I already follow the testing procedure of new
controller.

>>Rotate the thumbwheel slowly until the LCD screen
displays the readings of
the left and right wheel sensors as follows: L Wheel:
<value> , R Wheel:<value> .

The LCD didn't show the text 'L wheel and R Wheel'
eventhough I already rotate the wheel.

I already slide the sensor and screw all the way
to the rear end of the slot and extend
the sensor as far over the side of the
chassis as possible, as the instruction command.

When my Robot run 'Navigate Square', he can do it, but
not perfectly square.

Please help.

Thank you
