Lowrance 5150c 操作指南

Also remember that this unit will always show navigation information 

in the shortest line from your present position to a waypoint, regardless 

of terrain! It only calculates position, it can’t know what’s between you 

and your destination, for example. It’s up to you to safely navigate 

around obstacles, no matter how you’re using this product. 

Many instructions are listed as numbered steps. The keypad and arrow 

"keystrokes" appear as boldface type. So, if you're in a real hurry (or 

just need a reminder), you can skim the instructions and pick out what 

menu command to use by finding the boldface command text. The fol-

lowing paragraphs explain how to interpret the text formatting for 

those commands and other instructions: 
Arrow Keys 
The arrow keys control the movement of dotted cross-hair lines on your 

mapping screen called the cursor. The arrow keys help you move 

around the menus so you can execute different commands. They are 

represented by symbols like these, which denote the down arrow key, 
the up arrow, the left arrow and the right arrow: 

↓ ↑ ← →. 

Keyboard 
The other keys perform a variety of functions. When the text refers to a 

key to press, the key is shown  in bold, sans serif type. For example, the 

"Enter/Icons" key is shown as 

and the "Menu" key is shown as 

. 

Menu Commands 
a menu command or a menu option will appear in small capital letters, 

in a bold sans serif type like this: 

. These indicate that 

you are to select this command or option from a menu or take an action 

of some kind with the menu item. Text that you may need to enter or 
file names you need to select are show in italic type, such as trail name. 
Instructions = Menu Sequences 
Most functions you perform with this unit are described as a sequence 

of key strokes and selecting menu commands. We've written them in a 

condensed manner for quick and easy reading.
