Lowrance 250c 操作指南

4 

When operating on external power the iWAY is designed to enter a 

Standby mode if the external power source fails. For full details see 

the discussion of power button functions in Section 4. 

The iWAY has an optional Standby Mode (on by default) which allows 

the unit to conserve power while not in use. When the iWAY is in 

Standby Mode it will activate quickly when powered up. If the iWAY is 

running on external power and the power source is removed the iWAY 

will display a dialog box informing you that it is about to enter Standby 

Mode. If you want to keep operating the iWAY touch the screen to in-

terrupt automatic Standby. However, if the iWAY does enter Standby 

in this manner it will automatically restart (or "wake up") as soon as 

external power is reconnected. 

These features of Standby Mode can be particularly useful in vehi-

cles where the ignition controls the cigarette lighter. In such vehi-

cles connect the iWAY to external power. Turning the car off will 

automatically place the iWAY in Standby and starting the car will 

restart the iWAY. 

On the left side of the unit are two sockets for external connections. 

These are, from top, the USB cable connection and the headphone con-

nection. The sockets on the right side of the iWAY, from top, are the 

external GPS antenna, MMC card slot and external power cord. The 

power button also is located on the right side of the unit. 

Certain vehicles are equipped with special windshields containing 

metal in the glass. These models may prevent any GPS unit from 

receiving satellite signals and establishing a "lock." If the GPS will 

not navigate inside, test it outside the car. Also, confirm the wind-

shield type by consulting your vehicle's owner's manual or the vehi-

cle dealer. If the iWAY has difficulty receiving satellite signals you 

can use an optional external antenna. Some of these windshields 

have a specific location where the external antenna will work. Oth-

erwise you must place the external antenna near a side window, a 

rear window or on the car exterior with the magnet mount. To buy 

an external antenna, see the accessory ordering information inside 

this manual's back cover.
