Note:

a.When welding products, an electric iron with reliable grounding is needed. The welding temperature shouldn’t be too high,and the welding time shouldn’t be too long, The circuit soldering repetition can’t exceed triple times.
b.± 15V power supply port can not be reversed, and single electrical connection is not allowed(+15V or -15V).
c.In order to prevent electrostatic damage ,please avoid touching the circuit pins directly.
d. Please pick off the protective cap when using this product in the system.
e. An alcohol wipe to clean the products is recommended.
