8-1-1 MAIN BANG SUPPRESSION
(Usually, doesn’t need set up. adjust if necessary)
This adjustment is decrease the transmitted signal which appears as a circular echo around the
center.
Adjustment is done so as to main bang is observe slightly seen.
Excess adjusting is danger for nearest small target observation.
If the main bang is not so big, use as factory setting.

Vector shows the movement of the target.
Vector Constant large. Vector is stable, but the response is slow.
Vector Constant small. Vector is unstable, but the response is quick..
Tap Vector Constant, setting Bar appears lower part of
screen.
Set up by flick or tap + -.
Rotary knob adjusting is possible. Click and set.

DETAIL PERFORMANCE SETTING
Gate Size:
Set up the region size which can search the moving target automatically.
Wide region:
Possible to track fast moving target, but many clutters are include.
Sometime do miss tracking because of much noise.
Narrow region
Possible to track stable, but fast moving target are tend to lost.
Because of first target soon goes outside of the region.

8-3-1 PULSE REPETITION FREQUENCY FINE TUNING (PRF ADJUST)
When existing the same frequency radar, in the same area, they interfere each other.
If p.r.f.(pulse reputation frequency)is the same, Interference can’t reject on the screen.
In that case shift the p.r.f. a little may decrease the radar interference.
PRF Fine Tuning:
If radar interference cannot reject completely, it is effective way to shift the PRF.
Watching the screen echo, rotate the
Rotary knob and stop when radar
interference are fade out from screen.

DETAIL PERFORMANCE SETTING
8-3-2 STAGGER TRIGGER
When existing the same frequency radar, in the same area, they interfere each other.
If p.r.f.(pulse reputation frequency)is the same, Interference can’t reject on the screen.
Another way to decease interference is shift the transmitting time randomly.
Not synchronize signal which transmit randomly is eliminate.
So decrease the other radar interference echo on screen.
ON Stagger: Stagger trigger is generated
OFF Stagger: Stagger trigger stop. (Normal trigger timing)
Select and Tap
Watching the screen echo, select off or on
when heavy radar interference on screen.

8-3-3 SCANNER ROTATIONAL SPEED
The rotational speed of inside microwave radiator is possible to change.
The sensitivity of radar are low speed is more higher.
So scanner rotation speed is possible to change according observing range.
Every pulse length can select the Antenna rotation speed.
Short range uses short pulse (SP).
Medium range uses medium pulse (MP)
Long range uses Long pulse (LP)
Shorter range requires the High speed refresh screen.
Longer range requires the Low speed for High sensitivity.
User can select rotational speed according to his request.

8-3-4 ECONOMY MAGNETRON SETUP (PRF , PULSE LENGTH)
The life of magnetron proportion to the total transmitting pulse power.
Low power transmission makes magnetron life more longer.
Selection
Normal:
It is the usual factory setup. Usually, this is chosen.
Economy: Selected the shorter pulse, repeat frequency is also selected lowest 650 Hz.
The life of a magnetron keeps more longer time.
Sensitivity is decrease somewhat from Normal.
High Power: High sensitivity high performance.
Select and Tap
return to the menu
8-3-5 TIMED TX
The life of magnetron proportion to the total transmitting pulse power.
Timed TX can save magnetron life longer.

8-3-6 TUNE PEAK LEVEL
Normally, adjustment is not necessary.
(In case of adjustment the tuning peak point is shifted from maximum echo point.)
This adjustment must be done with (8-3-7 Tuning indicator) alternately.
Set RANGE at 24NM
Display tuning level indicator menu.
Tune maximum echo point.
At this point adjust tuning level, so as to seen within the green bar.
Adjusting data is 0 to 127
8-3-7 TUNE INDICATOR LEVEL
Normally, adjustment is not necessary.
(Adjust ,in case of tuning level is too low.)
Set RANGE at 24NM
Display the Tune Indicator menu.
Tuning region is 0 to 127
NOTE! If tuning level is too excess setting, can’t work automatic tuning function.
Adjust the tuning level bar moves within 80 to 90%.
