Tune the Radar
The radar can be tuned automatically (Auto Tune) or manually (Manual Tune). Tuning is used to optimize the
radar system settings.
NOTE:
For best results, run the tuning while there are targets within range, so it will be easier to review the data and make
adjustments.
CAUTION!
Do NOT interrupt the power or press any keys on the control head while it is tuning.
1.
Select Tune from the Installation menu.
2.
Select Auto Tune or Manual Tune:
Auto Tune:
Press the RIGHT Cursor key to start Auto Tune. Follow the on-screen instructions as
the control head stops radar transmission and starts automatic radar tuning.
OR
Manual Tune:
Press the RIGHT Cursor key to open the Manual Tune submenu. Use the 4-WAY
Cursor Control key to select and adjust the following settings:
•
Fine
(0 - 255; Default = 50)
•
Coarse
(0 - 255; Default = 50)
3.
Auto Tune Complete:
The screen displays a dialog box to start radar transmission. Follow the
on-screen prompts. Press the RIGHT Cursor key to select Yes or press the LEFT Cursor key to select
No. It is not required to start radar transmission when the tuning is completed.
If the radar was tuned manually,
press the EXIT key to return to the Installation menu.
Adjust the Trigger Delay
Trigger delay adjusts the signal timing so that long straight targets appear straight on the display.
NOTE:
The following settings must be in place to optimize the Trigger Delay setting: Gain = 0, FTC = 0, STC = 0. See
Adjust
Radar Settings
for more information.
1.
Select Trigger Delay from the Installation menu.
2.
Use the 4-WAY Cursor Control key to select and adjust the following settings:
Gain:
Press the RIGHT or LEFT Cursor keys to adjust the gain. The gain controls the amplification
of the radar signal. (0 - 255; Default = 0)
Trigger Delay:
Press the RIGHT or LEFT Cursor keys to adjust the trigger delay. A high number sets
a longer delay, while a low number sets the radar to a shorter delay. (0 - 255; Default = 166)
