2.  RADAR, CHART RADAR OPERATION

To tune the radar, start by setting the brilliance to a comfortable level, adjusting the 
gain until the background speckle just disappears, and selecting the 48 NM range. 
Then, do the following:

1. Select a weak contact somewhere near the edge of the screen and concentrate 

on that, while adjusting the gain control in small steps - allowing at least two sec-
onds between each step - until the chosen contact is as big, bright and consistent 
as possible.

2. Click the [TUNE] button on the InstantAccess bar to display [TUNE MAN].
3. Put the cursor on the tuning bar.
4. Spin the scrollwheel to tune. The best tuning point is where the bar swings maxi-

mum. The arrow below the bar shows the tuning control position; not the tuning 
condition.

The pulse length in use is displayed at the top-left position on the screen, using the 
indications shown in the table below.

Appropriate pulse lengths are preset to individual range scales and function keys. If 
you are not satisfied with the current pulse length settings, you can change them as 
shown below.

You can select the pulse length for the 0.5 to 24 NM range 
scales as shown below.

1. Open the menu then select [1 ECHO], [1 CUSTOM-

IZE ECHO] and [8 PULSE] menus to show the 
[PULSE] menu.

2. Do one of the following:

Control Unit: Press appropriate numeric key to select 
corresponding item number.
Trackball module: Click appropriate item.

3. Select desired option by pressing the numeric key 

pressed at step 2 or spinning the scrollwheel.

4. To confirm selection, press the ENTER key on the 

Control Unit, or push the left button.
