Press 'LEFT' and ‘RIGHT’ to adjust the value. The range is ± 127.
Selecting the correct value will require experimentation. When calibration is
completed test drive the wheelchair. Select a Veer Compensation value so that
the wheelchair does not veer when the joystick is pushed directly forwards or
backwards. If the wheelchair veers right, press ‘LEFT’; if the wheelchair veers left,
press ‘RIGHT’.
If a large compensation value is required, the mechanical position of the position
sense potentiometer may require adjustment - see section 5.3.3.
Press 'NEXT'.

If the steering motor drives to the wrong lock position during initial setup either:
•
reverse both the motor wires and both steering pot end wires (pot + and
pot -), or
•
use Wizard to swap the Left Lock and Right Lock parameter values,
then try calibration with the HHP again.
