• OK/NG judgment conditions
◆
OK/NG judgment of Gyro output values
(Determine differences between Gyro output value and Offset standard values and make OK/NG judgment.)

USABLE range is OK range of parts with secular change considered. (The screen displays USABLE.)
OK range is criteria to judge if they are within OK range at the time of shipping inspection.
Service division is expected to determine parts to be OK items when they are Usable.
• After the test, use [AV] key to return to the main menu.
When some errors occur to each inspection item, the following error messages are displayed.

When no API response is returned from GPS unit, this will be displayed.
Following incidents can be causes for it.
• Timeout occurs just because something is wrong with serial interface
(poor contact), or data gets garbled and looks like another response.
• When a response different from the requested API is returned
because of malfunction of GPS unit and another request for API is
already requested, the time-out response to the first request is
determined to be incorrect one.
• Navigation system performs so slow that it cannot handle the
response within the time limit even though a response is returned
from GPS unit, or GPS unit cannot handle the same kind of situation
within the time limit. (The time limit is 1.5 sec.)

Displayed message
GPS UN-CONNECT When communication between the navigation system and GPS unit is not
established for some reason, this will be displayed.
This can be mainly because something is wrong with the hardware.
Something can be wrong with the navigation system itself, serial interface
(including poor serial connection), and GPS unit.
