2.3 USAGE OF THE PRODUCT
2.3.1 As soon as power is supplied, the Product transfers to the mode of course
and speed data display; herewith gyrocompass and log readings are displayed as zeroes,
see Figure 6. Signal is absent on the converter’s output. The Product requires an input of
initial course values and gyrocompass and log types.
Unless initial course values and types of gyrocompass and log are entered, the
Product will stay in waiting mode, and alarm will work.
To ensure proper operation, select gyrocompass type and log type in the menu set-
tings, see 2.3.8 and 2.3.9, and input manually current course data of used gyrocompass.
If received compass and log data are invalid, the display shows «?»(a question
mark) –in the beginning of the relevant line.
