• 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.

Service Guidelines

Service Guidelines

• 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.
