CAUTION

Be sure to use a cable which conforms to specifications listed in "11-2 Communication Cable Specifications".
The settings will be invalid if other cables such as POPCOM communication cables or those having different
specifications are used.
After changing the parameters, turn the power off and then turn it on again to enable the settings.
The TPB can be used even if the parameters have been changed.
