INITIAL ACTIVATION
AERIS Watch type dive gauges are placed in a Deep Sleep mode prior to being shipped from the factory. The intent is to extend
storage life of the Battery for up to 7 years, before the unit is initially placed in service.
In this mode, Date and Time are updated as they normally would be. However, they are not displayed. Upon waking the F11 up, the
correct Date and USA Pacific Time will be displayed and it will be ready to operate with full functions.
To wake the F11 up from Deep Sleep mode, simultaneously depress the upper/right (S) and lower/left (A) buttons for 2 seconds until
the display comes full ON displaying the MAIN TIME screen, then release them.
Once the F11 is brought out of the Deep Sleep mode, it can only be placed back in it by the factory.

INTERACTIVE CONTROL CONSOLE
The Interactive Control Console consists of four Control Buttons that allow you to select mode options and access specific informa-
tion. They are also used to enter Settings, operate the Backlight, and access additional screens of information.
Throughout this manual they will be referred to as the M, S, L, and A buttons.
• Upper/Left - Mode (M) button
• Upper/Right - Select (S) button
• Lower/Right - Light (L) button
• Lower/Left - Advance (A) button
OPERATING MODE STRUCTURE
Unless it is operating in Free Dive mode, the F11 will display Watch Main Time (Fig. 1), like a standard Watch, until the mode is
changed.
The A button is used to access other Watch functions that include an Alternate display, Countdown Timer, Chronograph (stop
watch/run timer), Daily Alarm, and Time settings. The M button is used to access and return from the Free Surface Main screen.
The screens of the Main and sub modes will remain on display until a button is pressed to access another screen or mode, activate
a sequence, or for 2 minutes if no button is pressed. The Chronograph remains on display unless turned Off or another mode is
accessed.
When operating in Free Mode, the F11 will enter Dive Mode upon descent to the DSD (Dive Start Depth) previously set which can
be 2, 4, or 6 FT (feet) or 0.6, 1.2, or 1.8 M (meters) for 1 second.
See page 19 for Set DSD.
OPERATION AS A DIVING GAUGE
Entering Settings relating to diving activities is only available in Free Surface Mode which also allows access to a Countdown Timer
(separate from the Watch CDT), Log, and History Modes.
COMPUTER INTERFACE
Interface with a PC or Mac, to allow uploading settings and downloading data, is accomplished by connecting the F11 to a PC or
Mac USB port using the special AERIS USB interface cable.
The software program together with the USB driver required is on the AERIS Product CD, or it can be downloaded from the AERIS
web site. The program's Help serves as the user manual which can be printed for personal use.
The settings upload portion of the computer interface program can be used to set/change the Main Time, Date, Set Alarms group,
and Set Utilities group using the same interface system.
Information available for retrieval (download) from the F11 to the download portion of the program includes dive number, surface
interval time, start depth, end depth, maximum depth, elapsed dive time, start date, start time, lowest temperature under water,
sampling rate, dive profile, and set points.
The computer interface program also allows update of select versions of the F11's firmware (operating system software).
•
Refer to page 29 for more details relating to the computer interface system.
GRAPHIC MESSAGES
The segmented digits of the LCD are used to present various messages such as alarms, day of the week, modes, items being set;
and graphics such as On, Off, Set, Last, Log, Hist.
AUDIBLE ALARM
A LED warning light, located at the 6 o'clock position on the side of the housing, is synchronized with the Audible alarm. It will
flash as the Audible sounds, then turn off when the Audible shuts off. The Audible and LED will not be active if the Alarm is set OFF,
an Alarm group setting which completely disables it.
When alarms strike, the Backlight will come On if Off and remain On until you turn it Off by pressing/releasing the L button or it
turns Off automatically after 10 seconds.
Situation that will sound (2) 2 second beeps -
• RTI (Repeating Time Interval) alarm, if set On.
Situations that will sound 3 sets of (3) 1 second beeps -
• Watch Daily Alarm (surface only), if set On.
• Watch Countdown Timer reaches 0:00 (hr:min), if set On.
• Free Mode Countdown Timer reaches 0:00 (min:sec), if set On.
• SRT (Surface Recovery Time) alert, if set On.
• RDI (Repeating Depth Interval) alarm, if set On.

• Depth Alarms DA 1 to DA 6, if set On.
BACKLIGHT
To turn the Backlight On, press and release the Light button (< 2 seconds). The Backlight will remain On for the Duration time set (a
Set Utilities selection) unless you turn it Off during that time.
• The Backlight will come On (even if set OFF) when alarms strike and remain On until turned Off or automatically after 10
seconds .
• Pressing and releasing the Light button (< 2 seconds) while the Backlight is On will turn it Off.
• Depressing the Light button for 2 seconds while the Backlight is On, will reset the timer and extend the On time to the full
Duration time set.
• If the Light button is depressed for > 60 seconds, the Backlight will be disabled and not turn On until the button is released then
pressed/released again.
• The Backlight will be disabled when there is a Low Battery condition, and be re enabled once the battery is replaced.
• Extensive use of the Backlight reduces Battery use life.
• Turning the Backlight Off when it is not being used will help extend Battery use life.
• The Backlight does not operate when the unit is connected to a PC or Mac.
AUTO GLO
When Auto Glo (a Set Utilities selection) is set On, Backlight operation on the surface in Watch and FREE modes is controlled as
it normally would be by the Light button and Duration time set.
Upon entry into Dive mode, the Backlight activates (turns On) automatically and remains On throughout the full dive until entry
into Surface mode when the Backlight operation reverts to normal.
POWER SUPPLY
The F11 utilizes (1) 3 volt CR2450 Lithium Battery.
Battery voltage is checked every 2 minutes during operation while on the surface.
• If voltage decreases to the Warning level (2.75 volts), the Battery icon will appear on the Watch Main Time and Free Surface
screens (Fig. 2a) as an indication that the Battery should be changed prior to commencing a series of dives.
• If voltage decreases to the Alarm level (2.50 volts), the Battery icon will flash and operation will automatically revert to Watch
Main Time and only operate in Watch modes until the Battery becomes completely depleted.
• Low Battery Warning/Alarm conditions are not displayed during Dive Modes.
• If a Low Battery condition was not displayed prior to starting a Dive, and a Low Battery condition occurs during the dive, there
will be sufficient Battery power to maintain operation for the remainder of that dive. Upon surfacing, the graphics CHNG >>
BATT will alternate (Fig. 3), then operation will automatically revert to and remain in Watch Main Time until the Battery becomes
completely depleted.

The Set Audible feature provides complete OFF control of the Audible and its associated LED warning light. When set OFF, no
beeps will be emitted and the light will not flash when an alarm condition occurs, which some divers prefer during select activities.
Icons and messages will still flash and the Backlight will still come On.
The SRT (Surface Recovery Time) Alarm provides an alert when a set 'recovery time' has elapsed after surfacing from a dive.
The RTI (Repeating Time Interval) Alarm repeats each time the Time Interval set is reached during operation in Dive Mode.
The RDI (Repeating Depth Interval) Alarm repeats each time the Depth Interval set is reached, except when the DA alarms strike. If a
series of descents, ascents, descents is made, the alarm will activate during each of the Descents.
The DA 1 to DA6 (Descending/Ascending) Depth Alarms are set and operate with no restrictions (such as sequence) while ascend-
ing as well as descending. Unless set Off, the audible sounds for the number of beeps set for that depth each time you reach (pass
through) the Depth set while descending and/or ascending.

SET UTILITIES
Sequence: Lead-in >> Units >> Wet Activ >> Water Type >> Backlight Duration >> Auto Glo >> Sampling Rate >> DSD >> BDSI.
• A (< 2 sec), while viewing Set Alarms Lead-in, to access Set Utilities Lead-in.
The Wet Activation feature allows you to disable activation of Dive Mode during activities when you only want to use the Watch
features and don't want diving information displayed or recorded.
The Water Type selection determines Depth calibration to accomodate activities in fresh or sea/salt water.
The Backlight Duration determines how long the Backlight will be On when activated by pressing the Light (L) button.
When Auto Glo is set On, the Backlight will activate automatically upon entry into Dive Mode and remain On until the BDSI time (up
to 1 min) elapses after surfacing. L button operation of the Backlight will be disabled during the dive, then enabled on the surface.
Sampling Rate determines the interval at which data is sampled and recorded for upload to the Computer Interface program. It
does not affect the rate at which data is measured for the display (which is at fixed 1 second rate).
The DSD (Dive Start Depth) feature allows you to select the Depth at which Dive Mode will be activated upon descent. Regardless
of the DSD set, every dive ends upon ascent above 2 FT (0.6 M) for the BDSI set.
The BDSI (Between Dive Surface Interval) feature allows you to select the time interval between surfacing and descending that
determines whether the descent is a new dive. Short intervals may be preferred for some activities and longer intervals for others,
thus a selection may be helpful.
At any time while entering settings -
• M (2 sec), or 2 minutes of no button action, will revert to SURF MAIN.

LOG & HISTORY MODES
• A (2 sec), while Watch Main Time or FREE SURF Main is displayed, will access and step through Log and History modes.
Sequence: Main >> Day Log >> Full Log >> Day History >> Full History.
Day and Full Logs display information from the latest 99 dives.
The difference between the modes is that the information in Day Log is only retained until a dive is conducted on a new calendar
day, or the Dive # is reset to #1 (by A+S while viewing the SURF Main) at which time all data is deleted from the Day Log.
Full Log retains information until it is overwritten due to storage capacity.
After exceeding 99 dives, the most recent Dive will be recorded in the Full Log while deleting the oldest. It is highly unlikely that
this will affect the Day Log which will do the same if 99 is exceeded.
Dives are numbered 1 to 99. Numbering starts at #1 each new calendar day beginning after midnight, or when Reset (by A+S
while viewing the SURF Main).
In the event that a dive’s EDT exceeds 59:59 (min:sec), the data at the 59:59 interval will be recorded for the Log and History
upon surfacing of the unit.
History records information accumulated during the most recent day and adds that information to a full (all time) record.
Battery replacement will not to delete Log or History data.
At any time while in Log or History modes -
• M (2 sec) at any time while, or 2 minutes of no button action, will revert to the Watch Main or SURF MAIN screen.
• L (< 2 sec) - to toggle the Backlight On/Off.
Will be On for the duration time set.
• L (2 sec), while the Backlight is On, - to reset the timer to keep it On for the full duration time set.
