26.1.3 Gray scale test
Set brilliance and contrast to calibrated positions. Use the gray scale test to visually inspect neutral shades of grey.
Note: During any selftest, the ECDIS becomes inoperative and this is indicated by sounding the buzzer and flashing
the lamp in the SYSTEM FAILURE key on the keyboard-equipped control unit.
To activate the grey scale test, do the following:
1. Spin the thumbwheel to show Menu/Info/Chart Menu in the mouse functions area and then push the left mouse
button.
2. Choose Initial Settings from the menu and then push the thumbwheel.
3. Place the cursor on the triangle in the dialog box, choose Selftest from the menu and then push the thumbwheel.
4. Click the OK button. The system will end normal operation and start the Selftest mode.
5. Choose Display and then push the left mouse button.
