Uniden Clock - Manual (Page 17)

SETTING THE SHALLOW WATER ALARM
Located just below the LCD window are two keys labeled “DOWN” and
“UP” Alarms. These keys are used to set the Shallow Water depth alarm
so that it will audibly alert you if you enter water shallower than your
preset depth alarm.
To set the alarm, press the “DOWN” key. The LCD shows an alarm
depth of A03. Pressing the “DOWN” continuously cycles the alarm
setting deeper by one foot increments from A03 through A10 (for
example: 3, 4, 5, 6, 7, 8, 9, 10). After A10, the alarm settings are by
2-foot increments (for example: 10, 12, 14, 16, 18, 20 feet). The alarm
settings jump by 5-foot increments (for example: A20, A25, A30).
When you see a digital readout proceeded by an “A”, this is your ALARM
setting. This number appears in the display window immediately after
you press either alarm key and then will disappear after several seconds.
This number remains in the unit’s memory until power is turned off.
To decrease the alarm setting, press the “UP” key. The display will show
these numbers in decreasing value so that the alarm is shallower.
Several seconds after you press either the “UP” or “DOWN” keys, the
instrument displays the actual depth reading. A00 indicates the alarm is
off.
