PATENT NOTICE

U.S. Patents have been issued, or applied for, to protect the following design features: Dive Time Remaining (U.S. Patent no. 4,586,136), Data Sensing and Processing Device (U.S. Patent no. 4,882,678), and Variable Ascent Rate Indicator (U.S. Patent no. 5,156,055). User Setable Display (U.S. Patent no. 5,845,235) is owned by Suunto Oy (Finland).

DECOMPRESSION MODEL

The programs within the BUD simulate the absorption of nitrogen into the body by using a mathematical model. This model is merely a way to apply a limited set of data to a large range of experiences. The BUD dive computer model is based upon the latest research and experiments in decompression theory. Still, using the BUD, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression sickness, i.e. “the bends.” Every diver’s physiology is different, and can even vary from day to day. No machine can predict how your body will react to a particular dive proﬁle.

CONTROL BUTTON (B)

The Control Button (B) allows you to select display options and access speciﬁc information when you want to see it.

BAR GRAPHS

TLBG (Tissue Loading Bar Graph)

The TLBG (Fig. 1a) represents tissue loading of nitrogen, showing your relative no decompression or decompression status. As your depth and elapsed dive time increase, segments will add to the TLBG, and as you ascend to shallower depths, the segments will begin to recede, indicating that additional no decompression time is allowed for multilevel diving.

The TLBG monitors 12 different nitrogen compartments simultaneously and displays the one that is in control of your dive.

It is divided into a No Decompression zone (up to 3 segments displayed), a Caution zone (4 segments displayed, also No Deco), and a Decompression zone (all 5 segments displayed).

While you cannot provide a guarantee against the occurrence of decompression sickness, you may choose your own personal zone of caution based upon age, physique, excessive weight, etc., to reduce the statistical risk.

VARI (Variable Ascent Rate Indicator)

The VARI (Fig. 2a) provides a visual representation of ascent speed (i.e., an ascent speedometer).

The segments of the VARI represent two sets of speeds which change at a reference depth of 60 FT (18 M). Refer to the chart for segment values.

WARNING: At depths greater than 60 FT (18 M), ascent rates should not exceed 60 FPM (18 MPM). At depths of 60 FT (18 M) and shallower, ascent rates should not exceed 30 FPM (9 MPM).

When Ascent is too fast, (i.e., greater than 60/30 FPM, or 18/9 MPM), all segments will ﬂash and the graphic SLOW will be displayed (Fig. 3) until ascent is slowed.

Deeper than 60 FT (18 M)

Fig. 3 - ASCENT ALARM

Fig. 4 - CURRENT DEPTH

It is imperative that you understand the formats, ranges, and values of the information represented to avoid any possible misunderstanding that could result in error.

Current Depth is displayed on the Main Dive screens (Fig. 4a).

While at a No Deco Safety or a Deco Stop, the required Stop Depth is displayed on the Main (Fig. 5a).

Max Depth is displayed on Alternate Dive screens (Fig. 6a).

Times are shown in various formats.

• Hour:Minute - Dive Time Remaining (Fig. 4b), Elapsed Dive Time (Fig. 6b), Surface Interval, Fly, Sat.

• Minute:Second - Safety Stop Time (Fig. 5b).

Altitude is displayed as a range from L2 to L7 on the Surface Main when at elevations above 3,000 feet. It is not displayed at Sea level, which extends up to 3,000 feet elevation. Refer to the table on page ??.

POWER SUPPLY

The BUD utilizes (1) type CR 2430 Lithium 3 volt cell. Expected use life is approximately 100 hours if (1) 1 hour dive per day is conducted each time the unit is activated, up to 300 hours if (3) 1 hour dives per day are conducted.

Low Battery

Voltage level is checked upon activation and every minute during operation on the surface.

• When voltage decreases to the warning level (2.75 volts), the icon is displayed solid on the Surface Main (Fig. 7a).

• Upon decreasing to a voltage level that will no longer sustain proper operation (2.50 volts), the icon will ﬂash 5 times and the unit will shut off.

• If a low battery condition exists when the unit is activated (by pressing the button), the graphic bAT and the icon will appear ﬂashing for 5 seconds and the unit will shut off.

• If the button is not pressed to activate the unit prior to a dive, and a low battery condition exists, the icon will appear ﬂashing as a warning upon descent to 5 FT (1.5 M) and no other information will be displayed.

• If a low battery condition occurs during a dive, there will be sufﬁcient battery power to maintain operation for the remainder of that dive. Upon entry into Surface Mode, the Battery icon will appear (shell only with no inner bar) with the graphics CHG BAT ﬂashing (Fig. 8).

ACTIVATION

BUD OPERATING MANUAL

SETUP

BUD OPERATING MANUAL

ACTIVATION

To Activate the BUD, press and release B (the button).

• The unit will enter Diagnostic mode (Fig. 9), displaying all segments of the LCD as 8's, followed by dashes ( - - ), then a countdown from 9 to 0, checking the display and battery voltage to ensure that everything is within tolerance and functioning properly.

• After manual activation, it will also check the ambient barometric pressure, and calibrate its present depth as zero. Beginning at elevations of 3,001 feet (916 meters), it will recalibrate depth and adjust calculations every 2,000 feet (610 meters).

The BUD will also automatically activate by water contact. This is accomplished by bridging the gap between contacts located on the button and case.

If no dive is made within 2 hours after initial activation, the unit will automatically deactivate. If the wet contacts are still bridged, the unit will reactivate.

WARNING: If the unit is activated at elevations higher than 14,000 feet (4,267 meters), it will perform a diagnostic check and immediately shutdown.

SURF MAIN, information includes (Fig. 10):

> Surface Interval time (hr:min) with SURF icon; if no dive yet, this is time since activation. > Dive number with # icon, up to 12 for that operating period (0 if no dive made yet). > NX icon, if FO2 is set for Nitrox > DSAT (or Z+) icon, Algorithm selected.> TLBG with icon, if any after a dive. > Battery icon, if voltage is low.

• B (< 2 sec) to access ALT 1.

• B (2 sec) to access FLY/SAT, then step forward through other Surface selections.

Upon surfacing from dives, the Dive Main will remain on display for the ﬁrst 10 minutes with Surface Interval in place of NDC and the SURF icon ﬂashing (Fig. 11).

Fig. 9 - DIAGNOSTIC

Fig. 10 - SURFACE MAIN

(no dive yet)

After 10 minutes, the Surface Main will be displayed.

SURF ALT 1 (Last), information includes (Fig. 12):

> Elapsed Dive Time (hr:min) of dive previously made while still activated with EDT icons. > LAST icon. > Max Depth with FT (or M) and MAX icons, of dive previously made while still activated (3 dashes if MOD exceeded).

• B (< 2 sec) to access ALT 2*.

• Reverts to Main in 5 seconds if B is not pressed.

SURF ALT 2*, information includes (Fig. 13):

> Current %O2 saturation with SAT and O2% icons. > PO2 Alarm setting (ﬁxed at 1.40) with PO2 icon. > FO2 setting with FO2 and NX icons.

• B (< 2 sec) to revert to Main.

• Reverts to Main in 5 seconds if B is not pressed.

*ALT 2 is not displayed if FO2 was set for AIR.

SURFACE SEQUENCE Separate from the ALT screens, there is a sequence of selections in which you can -

> view Time to Fly/Desaturate. > set FO2. > select Algorithm. > set Conservative Factor. > view Plan NDLs. > set Units. > view Serial Number.

Press B repeatedly (2 sec each time), to access and step through the sequence then return to the Surface Main.

While in the sequence, operation will revert to the Surface Main if B is not pressed within a period of 2 minutes.

The sequence cannot be accessed during the ﬁrst 10 minutes on the surface following a dive.
