 (2)  Do a test of the controls on the indicators:
 (a)  
Turn the INT control clockwise.

 1)  Make sure the intensity of range marks, azimuth lines, alphanumerics, and the test pattern increases.

 (b)  
Turn the INT control counterclockwise.

 1)  Make sure the intensity of range marks, azimuth lines, alphanumerics, and the test pattern decreases.

 (c)  
Turn the INT control on the captain's indicator to the middle position.

 (g)  
AF 160, 162-171; Make sure each indicator shows the correct number of range marks and range mark messages as follows:

 NOTE: The test pattern must stay the same for all
____ ranges. The bands are related to the position on the indicators but not to the range.
 1)  Range to 20 - 4 range marks, 20-mi range message, and 5-mile range mark message.
 2)  Range to 40 - 4 range marks, 40-mi range message, and 10-mile range mark message.
 3)  Range to 80 - 4 range marks, 80-mi range message, and 20-mile range mark message.
