Timed Transmit—is used to save power, likely while at anchor. 

When Timed Transmit is 

On, the radar refers to the settings in Timed 

Transmit XMIT Time and Timed Transmit STBY Time. If 

Off is 

selected, the Timed Transmit XMIT Time and Timed Transmit STBY 

Time fi elds are inactive. 
Timed Transmit XMIT Time—determines a time interval in 

minutes the radar transmits. For example, if set to 01 min, the radar 

transmits for a period of one minute before referring to the Timed 

Transmit STBY Time. 
Timed Transmit STBY Time—determines a time interval in minutes 

that the radar is in stands by. For example, if set to 10 min, the radar 

stands by for a period of ten minutes before referring to the Timed 

Transmit XMIT Time. When the radar is standing by, the scanner 

does not rotate or transmit; however, power is still applied to the 

Magnetron, eliminating the need for a warm-up cycle.  

The Display tab contains settings for  Center Offset,  Rings, 

 Background color,  Heading Line,  Bearing Reference, and  Navigation 

Features.

 Center Offset—has three settings: Center, Look Ahead, and Auto 

Shift. Center places your current location in the center of the display. 

Look Ahead shifts your current location toward the bottom of the 

display, allowing you to view an area farther ahead. Auto Shift adjusts 

your location on the display according to the current speed.
