INSPECTION
PROCEDURE
1. INSPECT NAVIGATION ANTENNA ASSEMBLY (w/o Manual (SOS) Switch)
(a) Check that the navigation antenna assembly cable is properly installed and does not have any sharp bends, pinching or loose connections.
(b) Current consumption check:
(1) Measure the current consumption according to the value(s) in the table below.
Standard Current:

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.
