Lowrance electronic LMS-480M, LMS-480DF manual Show Waas Alarm, Software Version Information

The last field in this menu is CONFIG DST. 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.

Once you have each field set the way you want, press EXIT repeatedly until you return to the previous page.

Show WAAS Alarm

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:

1.Press MENUMENU↓ to GPS SETUPENT↓ to SHOW WAAS ALARM.

2.With the option highlighted, press ENT to uncheck it (turn off) and check it (turn on.) After the option is set, press EXITEXIT to return to the page display.

3.You can return to this command and press ENT again to turn the fea- ture on.
