Interpreting the test results display
• The program numbers of the MAIN and PANEL programs appear at the top of the display.
• The ROM, RAM, VRAM, NMEA1, NMEA2 and PANEL CPU are checked for proper
operation and the results displayed as OK or NG (No Good). For NG contact a FURUNO
agent or dealer for advice. The NMEA1/NMEA2 test checks the NMEA (monitor unit) /
NMEA (transceiver unit) ports.
• The TX FREQUENCY of the transducer is measured and displayed.
• ROLL and PITCH values change with ship’s pitching and rolling (range: -30° to +30°).
