GENERAL SAFETY
OPERATIONAL SAFETY
● The product must be charged with a 5V-1A adapter having IEC/EN 60950-1 approval.
● The instructions and warnings that the product bears on the labels attached to the
product and packaging must be strictly followed.
● Do not expose the product to liquids such as water. If liquids are leaked into the product
it may cause malfunction in the product or produce electric shock. In this case turn the
device off immediately and consult the authorized service center for inspection and/or
repair.
● Keep the product away from excessive heat sources.
● In order to prevent the risk of electric shock disconnect the product from the power
source in extreme weather (storms, lightning, etc.).
● Do not drop the product or place any other objects on the product.
● To avoid danger, keep plastic bags out of the reach of infants and pets.
● This product must not replace good orientation and mobility skills. This product only
notifies you about the obstacles between the head and waist level of your body. Please do
not use the product except for its intended use.
● Before using WeWALK, the user should receive training on the limits/capabilities of the
white cane.
● WeWALK must be used with a white cane with the proper alignment of the length
according to the height of the user. The length of the cane should be at least the same as
chest level or higher.
● Take care when unpacking as the folded sections of the white cane are held together
under tension by an elastic bungee in a similar manner to a traditional white cane, and they
will snap together when unfolded.
● In order to avoid malfunctions, use only recommended accessories.
● A round shaped and mesh covered ultrasonic sensor is posted at the front of the handle.
Do not press on it or try to manipulate it in anyway. Any damage to the sensor may cause
the product to perform poorly.
● Do not use the product in humid or rainy weather conditions which could deteriorate the
performance of the ultrasonic sensor and might cause a malfunction.
● Some obstacles may not reflect ultrasonic waves and therefore may not be detected by
WeWALK. The object must have a strong ultrasonic echo back to the sensor to be detected.
Large targets such as a liquid surface in a tank are detected at the maximum range. Curved
objects or sound absorbing materials such as fabrics reflect less energy directly back to
the sensor. Granular materials may absorb sound energy from the sensor due to surface
variation and/or angle of repose.
● Optimum operating temperatures are between 0 and 40 degrees Celsius.
● Ultrasonic functionality should be regularly tested to ensure correct functionality.
● Use this product at an altitude of less than 2000 meters above sea level.
