Lowrance 250c 操作指南

10 

Since the iWAY screen responds to pressure, with practice, you will 

learn exactly the right amount of pressure to operate the touch screen 

controls. Buttons are easy while scrollbars can be a little more chal-

lenging. 
NOTE: 

From time to time you may notice a slight delay between pressing 

an on-screen button and seeing the iWAY respond. The delay may 

be necessary while the iWAY retrieves information from the hard 

drive. If the iWAY does not immediately respond to a touch screen 

command look for the hourglass icon in the lower left corner of the 

screen. Wait until the hourglass disappears from the screen before 

entering another command. 

"Press and Drag" 
Some controls, such as the scrollbar or the zoom selection box which we 

will describe later in this section, require you to press and drag an item 

on the touch screen.  
The term "press and drag" will be used throughout this manual. It re-

fers to the motion of selecting an item on-screen by pressing on it then 

maintaining that pressure while you drag the item to a new location on 

the screen. 
Closing Menus 
Menus and dialogs that appear on your screen will all have an "X" icon 

in the top right corner, just like you are used to seeing on your home 

computer. Remember that all menus and dialogs can be closed by 

pressing 

. 

When using the iWAY in either Map Mode or Music Mode press the 

 button located in the top left corner of the screen to open the Main 

Menu. The Main Menu contains commands that let you switch modes, 

perform searches or customize the iWAY’s behavior.
