4.1.3 Transmitting delay time adjustment (TX DELAY)
This adjustment is intended to match the picture on the radar display with the distance of an actual
target by the adjustment of the transmission delay time. For the most accurate adjustment, find a close,
hard, long, straight object such as a quay wall. Select or chose within 100 m an object for the best
result. Transmitting delay time is adjusted in accordance with the following procedures.
(1)
Change the range scale to 0.25 NM by pressing “+” (or “-”) key on the Operation unit.
(2) Press MENU
key to display “Menu”.
Select [MAINTENANCE] => [STARTUP] => [TX DELAY] => [VALUE] will show the current
setting of the input value by highlighting the last digit value by the trackball/joystick.
(3) Move the trackball/joystick up or down to adjust the value to get a straight picture of the straight
object in the display as shown in Figure 4.1.
(4) Press ENT key to save the adjustment result.
Note: When you use inter-switch mode at first time, please set TX DELAY adjustment of each antenna.
These setting data are memorized in non-volatile memory, and applied automatically when each
antenna is selected.

key to display “Menu”.
Select [MAINTENANCE] => [STARTUP] => [ANT HEIGHT] => and set antenna height from the
sea level by the trackball/joystick, then press ENT key to save the setting.
