5.5.4.5.4 Changing the content of settings (ADJUST)
The items in the ADJUST menu are ones that need adjustment at the time of installation. The settings need not
normally be altered.
(1) Adjusting distance (TIMING ADJ)
This adjustment is necessary to adjust the distance on the radar screen to the actual distance.
(1) In preparation for adjusting the distance, the following adjustments are to be conducted.
First, set the radar range to 0.25 NM, FTC to minimum, and GAIN to optimum. Then adjust STC until the
pulse generated by your own radar appearing at the center of the screen is clearly recognized as a round dot.
(2) Adjusting the distance.
(2)-1 Select ADJUST by "common operations for CUSTOM", use up-down cursor keys to select TIMING
ADS from among the pull-down display items and press the "ENT" key.
(2)-2 As the distance adjustment screen is displayed, adjust timing until the center dot looks as (b) with the
control knob. If there is a linear target such as a bridge or breakwater, adjust timing until the target
appears straight in the screen.
(2)-3 When the adjustment is finished, press the "ENT" key to exit from the distance adjustment screen.

This adjustment is necessary to adjust the head direction on the screen to the actual direction of the ship.
(1) In preparation for adjusting the angle, the following adjustments are to be conducted.
(1)-1 Find one small target within a 0.5 to 1.5 NM range which, lying in the bow direction, can be detected
with eyes and is clearly visible in the radar screen.
(1)-2 Measure the bearing of this target from the bow direction using a compass. Let it bec.
(1)-3 Measure the bearing of the above target in head up (HU) mode using EBL. Let it ber.
(1)-4 Calculate the following:
c - r
ifc is greater than r
360 - ( r - c )
ifr is greater than c
This is the azimuth error of your radar at installation. If c and r are equal, the adjustment described below
is unnecessary.
