. This feature allows your unit 

to automatically adjust with the time change caused by Daylight Sav-

ing Time (you should only have to set it once). You may select which set 

of rules matches DST in your region, or simply accept the default.

When the signal is available, your unit will automatically use WAAS to 

boost the accuracy of the position fix. When the WAAS signal is lost or 

acquired, an alarm message appears. Since the U.S. government is still 

developing the WAAS system, it's not unusual for a GPS/WAAS re-

ceiver to frequently lose and reacquire its lock on a WAAS satellite. 

That can result in the alarm repeatedly going on and off. If you want, 

you have the option of turning off the WAAS Acquired/Lost alarm with-

out affecting how the unit uses WAAS. Here's how:

From time to time, Lowrance updates the operating system software in 

some of its products. These software upgrades are usually offered to 
customers as free downloads from our web site, www.lowrance.com. 

These upgrades make the unit perform better or introduce a new fea-

ture or function. You can find out what software version is running in 

your unit by using the Software Information command.
