* Each piece of information is effective following the initialization of CDEC. The updating interval is 432 ms. If not any of the modulated wave signals can be received (that is, the signal cannot be LOCKed), then a hyphen ("-") will be displayed. "If notany of the modulated wave signals can be received" it represents a condition that the modulated signals could not receive the signals described in section 4.2.Display example: If the satellite wave 1 = 10%, satellite wave 2 = 3.4% and terrestrial wave = 0.23%, the display will show [11_32_23].
