uations; however, even with the alarm audio off, you'll still see
the alarm messages displayed onscreen.
You can set the 961's alarms to emit seven different levels of
sound from low to high, or else turn the alarm audio off. The
ALARMS screen has two keys—LOUDER and SOFTER—that
you press to raise or lower the audio volume.
To adjust the alarm audio, press the STAR key to access the
ALARMS screen:
When you press the LOUDER key, you raise the ther-
•
mometer-style audio indicator, as well as the alarm audio
itself, to the next level. While you press and hold the
LOUDER key, a tone sounds to provide a sample of the
new volume setting.
When you press the SOFTER key, you lower the ther-
•
mometer-style audio indicator, as well as the alarm audio
itself, to the next level. While you press and hold the
SOFTER key, a tone sounds to provide a sample of the
new volume setting. To turn off the alarm audio, press the
SOFTER key until you reach the OFF setting.
The 961's TideTrack function calculates and selects tide infor-
mation for any of over 3,000 NOS/NOAA tide stations. Tide-
Track covers the entire U.S. coastline, including Alaska and
Hawaii, plus many Caribbean islands and western Canada.
You can display tides up to the year 2099. The data is from the
official tide-table predictions, and should be as accurate as the
printed tables. For more information about the printed tables,
refer to Tide Tables published by the NOS/NOAA, Rockville,
Maryland 20852.
With TideTrack, you can display tide-station information right
on the CHART screen. When you select a tide station that's
either near your vessel or somewhere else on the CHART
screen, a tide graph displays the tide height during any
24-hour period.
