      *a Component without harness connected
      (Navigation Antenna Assembly)
      *b Voltage Applied between Terminals

      Current consumption check:

      1. Measure the current consumption according to the value(s) in the table below.

        Standard Current

        Tester Connection Condition Specified Condition
        3 (core) - 3a (shield) 4.2 to 5 V applied between terminals 3 and 3a 10 to 30 mA
        NOTE:

        Do not apply 6 V or more between terminals 3 and 3a.

        HINT: 

        If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.

  2. INSPECT NAVIGATION ANTENNA ASSEMBLY (w/ Manual (SOS) Switch)
