Product Features This section introduces the features of the SPECTRA Silver. 2018 WALNUTT. All Rights Reserved. 7 SenDeck The SPECTRA Silver's SenDeck integrates 5 sensing areas to detect pressure changes on different sections. Perceive Your Posture Pressures at your feet change along with your body posture. With the unique perceiving system, SPECTRA Silver 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. How to Stand 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 Silver is fully compatible with these two postures.

- You are supposed to check the sensor modules before using the SPECTRA Silver. Refer to the "Device" on Page 17 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. 8 2018 WALNUTT. All Rights Reserved.

- The operation conditions of SPECTRA Silver are limited within -10 ~ 35 and under 85 kg. Long-time operation under high temperature and large load may cause sensor module failure therefore should be avoided.

- You MUST wear helmet and other safety equipment while riding the SPECTRA Silver.

- Use the eBoard Go app to change the start mode of the SPECTRA Silver. Refer to the

"Device" on Page 17 for more information.

- If you are just starting out using the SPECTRA Silver, you are suggested to choose the Stand Mode. Refer to the "Device" on Page 17 for more information. 2018 WALNUTT. All Rights Reserved. 9 Motion Control The SPECTRA Silver 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. Move Forward Lean slightly forward. The SPECTRA Silver will gradually speed up. Shift your weight backward to gently slow down until stop. Make Turns To turn left, lean your body to the left and press your rear foot on the left sensor module. Tilt the deck to steer more easily. You can turn right in the similar way. Use the Truck SPECTRA Silver 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 truck and the differential speed together bring you a better steering experience.

- 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. 10 2018 WALNUTT. All Rights Reserved. Cruise Function Cruise Function Slightly lift your front heel up and keep for 1.5 seconds, Cruise function will be activated, speed will remain as you keep your front heel up. Put back down your front heel, cruise function will be deactivated. Alarm: D - D (Every 2s ) Headlight: Flash (Every 2s) 4WD Braking The SPECTRA Silver come with four Hub Motor Wheels, SPECTRA can brake timely and reliably while ensuring the safety and smoothness. Decelerate & Brake Shift your weight backward. The SPECTRA will gradually slow down and stop eventually, unless you lean forward again. Alarm: D-D-D-

All Rights Reserved. 11 Speed Mode When you are riding on the SPECTRA, three different speed modes are available. The details of each start mode are found below. Mode Name Description Beginner Mode For beginners to get started. Speed and acceleration are limited: Approx. 8km/h. For users familiar with the SPECTRA Silver. Normal speed and acceleration: Approx. 15km/h For skilled users pursuing performances. Speed and acceleration limits are relaxed: Approx. 35km/h Sport Mode Pro Mode Ramp Assist The SPECTRA Silver embeds inside 6-axis sensors to perceive its attitude and the slope. Whether in uphill or downhill, you can still use the same posture to control the SPECTRA Silver freely. Uphill In uphill, the SPECTRA Silver will increase the motor outputs by itself. The maximum uphill slope is 36 %. The SPECTRA Silver may shut off the motors if exceeding such limit. Long-time riding in uphill will reduce the range. Downhill In downhill, the SPECTRA Silver will decrease the motor outputs and brake to slow down. The maximum downhill slope is 25%. Exceeding such limit may cause loss of control therefore should be avoided. 12 2018 WALNUTT. All Rights Reserved.

The SPECTRA Silver is stunning because of its unique material and original design, intuitive thanks to the revolutionary control method, full-range safe based on thoughtful consideration and protections, and extremely portable within amazingly small size and light weight. Do I need a remote controller?

No. The SPECTRA Silver knows your body postures and moves along with them. When you shift your weight forward, it speeds up; and when you shift your weight backward, it slows down. You can also use the eBoard Go app to interact with, configure and lock the SPECTRA Silver. Why does the SPECTRA Silver have a magnalium unibody?

The Magnalium body come with not just a light weight but also provides strong corrosion resistance and physical strength, and is integrated to a one-shaped body, presenting no additional holes or slits but only the artistic textures and the streamlined exterior. Is the SPECTRA Silver safe?

We put your safety in the first place from design to manufacturing. Whether the SPECTRA Silver or its built-in battery has adopted rigorous testing and qualified for various safety certifications. To ensure safety, whenever you jump off the SPECTRA Silver, it stops instantly. Meanwhile, to prevent any error or malfunction, the SPECTRA Silver tests its system and components, and warns you immediately in case of any abnormality detected. How do I learn to ride the SPECTRA Silver?

An interactive ride tutorial is provided for you to get started with the SPECTRA Silver. It usually takes only 5 minutes to go through all the process and handle the ride skills. You are also recommended to watch the tutorials videos on our website. How does the SPECTRA Silver turn?

The SPECTRA Silver applies different speeds on both wheels to make turns. For example, the right motor runs faster to turn left. The truck also rotates the front and rear axles in different directions to enhance the steering. 24 2018 WALNUTT. All Rights Reserved. How does the SPECTRA Silver brake?

The SPECTRA Silver uses both front motors and rear drum brakes to automatically brake according to your posture and speed. You can also lift front heels to make it decelerate. All braking forces are regulated intelligently to ensure safety and smoothness. How fast and how far could the SPECTRA Silver travel?

The SPECTRA Silver could run up to 35 km/h, and is designed to travel as far as 18-25 km. Since the built-in battery and motor performance is subjected to environmental factors, the actual speed and range may vary. Can the SPECTRA Silver run on ramps?

The SPECTRA Silver integrates attitude sensor to detect the ground slope and accordingly adjust the motor outputs. It accelerates in uphill or brakes in downhill to let you feel riding on the ground. But for safety, you should avoid riding on slopes exceeding limits (>36% uphill or >25% downhill). Can I take the SPECTRA Silver on the plane?

According to civil aviation authority regulations, electronic device with lithium -ion battery whose capacity is below 100 Wh can be placed in the carry-on luggage. Thus the SPECTRA Silver is in principle eligible for boarding since its capacity is 88.8 Wh. In addition, the SPECTRA Silver and its built-in battery also have air transport certificate to authenticate their safety. Since the regulations of airlines may differ in specific flights, periods or context, we recommend you to consult the airline of your flight in advance, especially the international flight. 2018 WALNUTT.
