Page 4: Welcome
TX1 He. The TX1 He was designed to create a user friendly dive computer that allows the use of Air, Nitrox, and Trimix. It is a powerful instrument indeed - with a digital compass, gauge mode, use of up to six transmitters, Gradient Factors, Hollis Dive Planning Software, and many more features to be discussed within.
Page 5: Warnings
If you dive in situations where your trip would be ruined or your safety would be jeopardized by losing the use of your TX1 He, a backup instrument system is highly recommended.
Page 6: Notices
The program within the TX1 He simulates the absorption of inert gases 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 TX1 He dive computer model is based upon the latest research and ex- periments in decompression theory.

PO2 BAR BUTTONS The TX1 He utilizes 3 Control Buttons that allow you to select mode options and access specific information. They are also used to link the Transmitter(s), enter Settings, activate the Backlight, and acknowledge the Audible Alarm. Throughout this manual they will be referred to as the M, A, and S buttons.

SURF • The unit will enter Diagnostic Mode displaying all segments of the LCD as 8's, fol- TX 1 lowed by dashes ( - - ), then a countdown from 9 to 0. It checks the display and volt- DIAGNOSTICS age to ensure that everything is within tolerance.
Page 13: Audible Alarm
TX1 He OPERATING MANUAL AUDIBLE ALARM While operating in NORM or GAUGE Mode the Audible will emit 1 beep per second for 10 seconds when alarms strike, unless it is set Off. During that time, the Audible can be acknowledged and silenced by pressing the S but- ton (less than 2 seconds).
Page 14: Pc Interface
*Prior to attempting to Download data from your TX1 He or Upload Settings to it, review the HELP section of the HCI program. It is recommended to print those sections of HELP that you consider appropriate for your Interface activities.
Page 15: Tx1 He Low Battery While On Surface
TX1 He OPERATING MANUAL TX1 HE LOW BATTERY WHILE ON THE SURFACE if Low Batt ≤ 2.75 volts (warning level) SURF • Backlight is completely disabled. NORM • Battery icon (shell with inner bar) appears solid. DIVE 0 • If a dive is started, the icon is not displayed on the dive mode screens.
Page 16: Transition Period
TX1 He OPERATING MANUAL TRANSITION PERIOD, upon surfacing: Operation shifts from Dive Mode to Surface Mode upon ascent to 2 FT (0.6 M) for 1 second; however, Surface mode 'screens' will not be available until a Transition time elapses. The reason for this is that making a descent during the first 10 minutes after surfacing from a NORM or GAUGE dive, is a continuation of that dive.

TMT as illustrated. The TX1 He cannot effectively receive a signal when it is held out to the sides of the TMT or held at distances greater than 3 feet (0.91 meters) in front of the TMT. Best reception is achieved when the TX1 He is within less than 3 feet (0.91 meterS) of the...
Page 36: Wet Activation
The contacts are the metal pins of the PC Interface Data Port and the stems of the buttons. When Wet Activation is set OFF, the TX1 He will not enter Dive Mode unless it is first activated by push button and operating in a surface mode or it is a repetitive dive.
Page 37: Algorithm
The settings on the TX1 He allow for a GF Low and a GF High setting. The TX1 He requires the diver to select between 5 GF presets or custom settings (0% to 90%) for both the GF Low and GF High settings.
Page 38: Deep Stop (Ds)
DIVE TIME REMAINING (DTR) The TX1 He constantly monitors nitrogen loading and oxygen accumulation, and will display whichever time is the least amount available as DTR on the No Deco Dive Main screen. The graphic NDC, or OTR, will identify which time is being displayed.
Page 39: O2 Time Remaining (Otr)
Gas Consumption and Depth are continuously monitored and GTR reflects any change in circumstances. For example, when you suddenly find yourself swimming against a strong current and begin breathing more rapidly, the TX1 He will recognize the change and adjust GTR accordingly.
Page 40: Total Ascent Time (Tat)
TX1 He OPERATING MANUAL TOTAL ASCENT TIME (TAT) SURF Available only on an alternate (ALT) screen when in a decompression requirement, FTMAX TAT displays the total time to the surface. For calculation, TAT assumes a strict fol- lowing of the current decompression schedule and prescribed gas switches. It takes into acount all decompression stops and a standard ascent time between stops.

Page 65: Reference
REFERENCE CAUTION: When the procedure provided in this section is used to change the TX1 He battery, you must be sure that the case O-ring is not pinched and that the TX1 He is water tight before conducting diving activities.
Page 66: Pc Interface
TX1 He OPERATING MANUAL PC INTERFACE The TX1 He is configured with a Data Port that enables it to be connected to a PC through a USB port using a special Interface Cable supplied or available as an optional accessory.
Page 67: Care And Cleaning
Protect the lens against scratches with a Instrument Lens Protector. Small scratches will naturally disappear underwater. • Soak and rinse the TX1 He in fresh water at the end of each day of diving, and check to ensure that the areas around the low pressure (depth) sensor, PC interface data port, and buttons are free of debris or obstructions.
Page 68: Battery Replacement
OPEN water into the unit. Damage due to improper Battery replacement (or sub- sequent leakage of moisture into the unit) is not covered by the TX1 He's 2 year warranty. When replacing the Battery in the TX1 He, it is recommended that you also consider replacing the Battery(s) in the Transmitter(s) to be used, and vice-versa.
Page 69: Inspection
• Orient the Retaining Bar across the lower portion of the Battery and carefully push it down into position. • Replace the Cover O-ring with a new one which must be a genuine Hollis part that can be purchased from an Authorized Hollis Dealer.
Page 70: Testing
TX1 He OPERATING MANUAL Testing > Ensure that the LCD is clear and sharp in contrast. If any portions are missing or appear dim, or if a Low Battery condition is indicated, return the TX1 He with Trans- DATA >SAVE? mitter to an Authorized Hollis Dealer for evaluation before use.

(P/N 204.2365) and the standard elastic band version. The shock cord version is excellent if you will routinely mount the TX1 He in the same position and use the same thermal protection. In this scenario the shock cord version will only need to be adjusted once.
Page 73: Adjusting The Shock Cord Version
TX1 He OPERATING MANUAL Adjusting the Shock Cord Version (P/N 204.2365) The shock cord should be fitted in position over any gloves, wetsuit, or drysuit. Keep in mind neoprene compresses with depth, and compensate the tension accordingly. • Knot one end of the shock cord.

Page 77 TX1 He OPERATING MANUAL ! WARNING: If your TX1 He stops working for any reason while operating, it is important that you have anticipated this possibility and are prepared for it. This is an important reason for not push- ing the tables, oxygen exposure limits, and a critical reason to avoid entering decompression, without proper training.
