Basic Timer Operation

Operation of the WTT4 and WTT5 Wake Turbulence Timers is simple and intuitive - a few minutes practice will show you everything you need to use the timers.  Refer to the drawing below.




Setup Menu

Display and button brightness and alert volume (if the option is fitted) may be adjusted by pressing the green Menu/Dim button when both timer sections are idle.  Brightness and volume have 16 levels to accomodate all conditions.

When the green Menu/Dim button is pressed, the yellow display will show [dSP] indicating it controls the display and button brightness and the red section will display [Snd] indicating it controls the alert volume level.  Press either yellow button to adjust brightness or either red button to adjust volume.  


Brightness

Press either yellow button in the menu mode to control brightness.  The yellow display will show the current brightness level between 0 (minimum brightness) and 15 (maximum brightness).  Pressing the left button decreases brightness.  Pressing the right button increases brightness.  Press the green Menu/Dim button when the brightness is satisfactory.

 
 Volume

Press either red button to adjust the volume.  The red display will show the current volume level between 0 (minimum) and 15 (maximum).  Pressing the left button decreases the volume level.  Pressing the right button increases the volume level.  A brief sound will be made at each step to judge the level.  Press the green Menu/Dim button when the volume level is satisfactory.
