7.5 Advanced Settings
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 con-
nected to the scanner).
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 incor-
rectly 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 CLEAR 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
Radar System Checks
and Adjustments on page 8-16 .
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 adjust-
ing the display timing.
