place exposed to strong vibration or a sloping surface. Doing so may cause the product to fall,
resulting in an injury or fault.

The product contains sharp edges that are left unavoidably exposed, such as jumper plugs.
Handle the product with due care not to get injured with such pointed parts.

Do not place anything on the product or expose the product to physical shocks. Do not carry the
