Incorrect timing is most noticeable on the
1
/
8
nm or ¼ nm range scales. Targets
such as bridges or piers appear bent or bowed.
Note: Under normal circumstances you do 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 this
menu is therefore via a hidden key press.

To adjust for correct timing:
1. Select the
1
/
8
nm range.
2. On the radar locate a straight dock, seawall or bridge that is facing your
ship. If the image is bent or bowed, as shown in the following diagram, then
you need to adjust the timing.

3. Press the
MENU
key to display the set up soft keys.
4. Press and hold the blank soft key directly to the right of the
RADAR SET UP
soft key for 5 seconds. The Advanced Set Up menu is then displayed.
5. Use the trackpad to move the selection bar down to the Display Timing
option.
6. Use the soft keys to adjust the Display Timing slider. As soon as you start
the adjustment, 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
/
8
nm range.
7. When the displayed image appears straight, press
ENTER
to return to the
Advanced Set Up soft keys.
8. Press
CLEAR
to return to the set up soft keys, and
CLEAR
again to return to
the normal radar screen.
Alternatively, you can use a VRM in conjunction with a target at a known
distance and adjust the picture so the target co-incides with the VRM.
