Chapter 1 Adjustment in installation
1.1 Menu usage
Refer to “
Menu usage
” (page3-1)
*About the shaded menu:
[Inters witch] in [System] menu, and [Sector mute], [Backup], [Transmission time] and [Operating time]
in [Maintenance] menu are not available during transmission, and they are all shaded.
1.2 Tuning method
The transmitted and received frequency of this radar may become detuned by environmental changes.
This results in “detuning” of the gain and the same image may be hard to be seen, even if the setup is
the same as before.
[Tuning method] can be changed directly in the upper light of the screen, with trackball and [ENT] key,
without using menu function.
Auto tuning
This function automatically compensates detune caused by environmental changes.
Sometimes, as auto tuning adjusts to optimize strong echo, weak echo may be weakened too much
when strong echo such as from land is received.
Adjust [AUTO ADJ] to optimize value if echo from the object target is weak.
[MENU] => [MAINTENANCE] => [STARTUP] => [TUNE AUTO ADJ]
Manual tuning
Perform all adjustments manually.
[MAN ADJ] adjustment is required whenever detuning is caused by environmental changes.
[MENU] => [MAINTENANCE] => [STARTUP] => [TUNE MAN ADJ]
[MENU] => [RADAR] => [TUNE AUTO ADJ]
Optimized value setup method
Adjustment shall be performed based on stable echo object such as from land. (Land is used in
following explanation.)
1 Set “RAIN” and “SEA” to 0.
2
Weaken Gain until land echo is nearly disappears.
3
Press [MENU] key, select [MAINTENANCE] => [STARTUP] =>.
4 Adjust [AUTO ADJ] or [MAN ADJ] to get the strongest land echo.
5
Repeat step 2 to 4 then adjustment is completed.
