• Precise adjustment should be made in a shield box or shield room where spurious
noise has been eliminated.
• When using magnetized tools, note that related magnetic elements may cause
malfunctioning of critical parts (such as IC).
• Use a twisted pair wire of thick type when measuring level. Using such a thick
twisted pair wire could reduce the measurement error as the wire contains less RF
resistance.
• When disassembling the phone set, you must use a driver tool meeting standard
requirements.
