8) Never change the design or add to the design of the device or electric circuit for this set. If you add to the design, it can cause danger to the safety. Also if you change the design or add to the design, the manufacturer’s warranty would be ineffective.
6) The voltage should not exceed 0.75V in any location and the current leakage must not exceed 0.75mA. * service precautions 1) When inserting the part or circuit board, you must keep the lead wire fixed to the end before soldering. 2) When inserting the high power resistance, leave about 10mm clearance from the board (metal oxidation coated resistance or metal coated resistance).
