*b Voltage Applied between Terminals


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


NOTICE:

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.


If the result is not as specified, replace the navigation antenna assembly.
