ROM, SDRAM and NMEA checks: Result is
shown as OK or NG (No Good). For any NG,
try the test again. If the result is still NG, con-
tact your dealer for advice. NMEA check
shows no result. This check is for factory use
only.

ation.

nately and a beep sounds with each push.
• [MODE] control: Rotate the control. The
name of mode selected appears above the
