3.5.1 [ECHO ADJUSTMENT] menu
Open the main menu then select [RADAR INSTALLATION] [ECHO ADJUSTMENT]
to open the [ECHO ADJUSTMENT] menu.
[VIDEO ADJUST VALUE]
Adjust the video level manually to remove noise.
Set the value so that noise just disappears from the screen. The setting range is -32
to +32 (default: +32).
Note: The setting range is 0 to +31 (default: +12) when the [MODEL] setting is set to
[50], see "[MODEL]" on page 3-12.
When using the number keys, the indication is first selected as a whole. At this time,
you can toggle between plus "+" or minus "-". Press the 8 key for "-", press the 2 key
for "+". If single digits are highlighted, toggle is not possible. In this case, press the
CANCEL/TRAILS key to re-highlight the whole indication.
[RING SUPPRESSION]
Remove “ring” noise which appears with the waveguide type radars. Adjust so the
rings disappear at the range of 0.125 m. The setting range is 0 to 255 (default: 1).
Note: This menu is NOT available when the [MODEL] setting is set to [50] (see
"[MODEL]" on page 3-12).
Preset the radar as follows:
• Interference Rejector (IR): 2
• Gain: 80
