The ADVANCED SET UP option allows you to set up values for the following
three parameters that affect the fine-tuning of the radar. Advanced settings are
only available from the Master radar display (that is, the display connected to
the scanner).
Parameters Function Slider Range
Display timing Corrects for display range error 0m to 153m
STC preset Equalises target levels across display 0-preset maximum
Tune preset Allows adjustment of the tuning 0-255
range controlled by the TUNE control
Note: Under normal circumstances you will not need to adjust these settings, as
they are set automatically at the factory. If these parameters are set incorrectly
the performance of the radar will be adversely affected. Access to the menu is
therefore via a hidden key press.

To change the settings:
1. Press the
MENU
key to display the set up soft keys.
2. Press and hold the blank soft key directly to the right of the
RADAR SET UP
soft key for 5 seconds. The Advanced Settings menu is then displayed.
3. Use the trackpad to move the selection bar to the required option.
4. Use the soft keys to increase or decrease the slider setting. As soon as you
start to adjust the setting, the menu page is cleared so that you can see the
effects of the adjustment on the radar picture, and the radar is set to 1/8nm
range.
5. Press
ENTER
to display the menu again.
6. Press

to return to the Menu soft keys, and
CLEAR
again to return to
normal operation.

If required, you can recall the factory defaults for this page. To do so, move the
selection bar to the
SCANNER RESET
option, press the
ADVANCED SETTING RESET
soft key, and press the
YES
soft key to confirm.
Display Timing
If you extended the inter-unit cable, you should have set the display timing
when you first installed your system, as described in
Section 8.9 .
Under certain circumstances, it may be easier to adjust the display timing with
MBS (Main Bang Suppression) off; press the
MBS
soft key to toggle the setting
OFF
. MBS is reset to
ON
automatically when you finish adjusting the display
timing.
