☞Service Guidelines Service Guidelines
•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.
•When making repairs with power on after connecting the test package, note that
dangers such as overcurrent, parts deterioration caused by short-circuit may occur.
•Note that PCB land may be detached due to overheating of a soldering iron while
making repairs on board status.
•Any additional devices that cause the change of performance shall not be added
to this phone, as registered.
