MODE Power switch behind the cover 2) Testing of main display and processor unit begins. Memory, LEDs and buzzer are tested in order, each tested eight times consecutively. Open the lid at the bottom of the display unit and press the [SET] key. The display should look like the illustration below, with the highest digit of distance run blinking. 1 2 3 0 0 nm: Before pressing [SET] key 0 0 1 2 3 0 0 nm: After pressing [SET] key Blinking 2. Repeat steps 2 and 3 to change other digits. Note 1: Distance run can be reset to zero by entering all zeroes. Note 2: To restore previous distance run setting, do not operate arrow keys or [SET] key for more than 10 seconds. When this is done the distance run indication stops blinking and then the previous setting is restored. Note that if the ship is moving at this time the distance run indication will change. Press the [SET] key. 10 System Settings The system settings do not require frequent adjustment. The table below shows setting range and default setting for each parameter.

[. . . ] In the processor unit of the DS-50, difference of "fo + fd" and "fo - fd" are computed to extract only the Doppler shift factor "fd". (fo+fd) -(fo-fd) = 2fd Since the 'fd' is theoretically given by fd = 2Vcos x fo/C (C: Sound velocity in water) and fo, C and are known, V can be calculated if the "fd" is given. Note that the sound velocity in water changes with water temperature and water pressure but the change by water temperature is automatically compensated for by using temperature sensor. 18 DIGITAL INTERFACE IEC 61162-1 EDITION 2 Output sentences of channel 1, 2 (NMEA/CIF 1, NMEA/CIF 2) VBW, VTG, VLW, VHW.
