Alarms
The 3500 has both a shallow alarm and a deep alarm. The shallow alarm
sounds if you move into water
shallower
than the shallow alarm's setting.
The deep alarm sounds if you move into water
deeper
than the deep
alarm's setting.
To use the shallow alarm, first press the up arrow
key. The screen shown at right appears. As you can
see, the shallow alarm is off. Quickly, press the up
arrow key to increase the shallow alarm's setting.
In this example, we set the shallow alarm to 10 feet.
Release the up arrow key and the 3500 automati-
cally switches to the deep alarm as shown below.
If you want to set the deep alarm, press the up arrow
key until the desired depth appears. When it does,
release the up arrow key. Wait a few seconds, and
the 3500 will erase the alarm display.
The alarms are now set. If you move into water shallower than the shal-
low alarm's setting or deeper than the deep alarm's setting, the appropri-
ate alarm will sound.
While an alarm sounds, you can adjust it's setting by pressing the up or
down arrow keys.
To turn an alarm off, repeat the above steps until the desired alarm ap-
pears, then press the down arrow key until the word "OFF" appears.
Release the down arrow key and wait until the alarm messages are cleared
from the display.
Note: The alarm settings are not stored in memory. If you turn the 3500
off, all alarm settings are erased. You will have to reenter the alarms each
time it's turned on.
