This section introduces the features of
SPECTRA Mini.

©
SPECTRA Mini's SenDeck integrates 2 sensing areas to detect pressure changes on different sections.
Pressures at your feet change along with your body posture.
With the unique perceiving system, SPECTRA Mini is able to
real-time analyze your body posture based on these pressure
signals.
Other valuable information, such as whether you are standing
stably or lifting your toes or heel, could also be recognized.
Refer to the standing postures
on the left. Separate your feet
into front and rear.
Whether you prefer your left or
right foot ahead, SPECTRA Mini
is fully compatible with these
two postures.
-You are supposed to check the sensor modules before using the SPECTRA Mini. Refer
to the "Device" on Page 16 for more information.
-The arrows on the surface mark the positions of sensor modules. Putting your toes or
heels on the arrows will help to perceive your body postures.

SPECTRA Mini moves along with your posture thanks to the well-designed and intuition-motivated
motion controller. Simply by tilting your body, you can freely move forward and make turns.
Once SPECTRA Mini gets ready to go, lean slightly forward.
The SPECTRA Mini will gradually speed up.
Lean your body backward to gently slow down until stop.
To turn left, lean your body to the left and press your rear foot
on the left half of the SenDeck.
You can turn right in the similar way.
SPECTRA Mini adopts the truck , a classic mechanism on every
common skateboard.
When you are leaning, try to tilt the deck. The tucks will rotate
the front and rear axles in opposite directions, which can help
turning greatly.
-The maximum uphill slope is 7°. The SPECTRA Mini may shut off the motors if
exceeding such limit.
-The maximum downhill slope is 5°. Exceeding such limit may cause loss of control
therefore should be avoided.
-To loosen the truck, use the supplied Hexagon Socket to turn the Kingpin Nut
counter-clockwise. This will help you to tilt the deck more easily when turning.
