REMINDERS FOR USING THESE PRODUCTS
Before using these products, be sure to request the delivery specifications.
SAFETY REMINDERS
Please pay sufficient attention to the warnings for safe designing when using these products.
When mounting on live electrical parts directly, there is a fear that an insulation accident is caused, so please consider on the design in
case of use.
There is a fear that sullenness of double sided adhesive tape occurs, so please refrain from the use to a part where you wind
repeatedly by which it's for the hinge part.
