GARMIN HR WW 3.1 Navy Wrist Dive Watch Instructions

IMPORTANT SAFETY AND PRODUCT  INFORMATION

WARNING
Failure to heed the following warnings could result in an accident or medical event resulting in death or serious injury.

Dive Warnings

• The diving features of this device are for use by certified divers only. This device should not be used as a sole dive computer. Failure to input the appropriate dive-related information into the device can lead to serious personal injury or death.

• Make sure that you fully understand the use, displays, and limitations of your device. If you have questions about this manual or the device, always resolve any discrepancies or confusion before diving into the device. Always remember that you are responsible for your own safety.

• There is always a risk of decompression sickness (DCS)  for any dive profile even if you follow the dive plan provided by the dive tables or a diving device. No procedure, diving device, or dive table will eliminate the possibility of DCS or oxygen toxicity. An individual’s physiological makeup can vary from day today. This device cannot account for these variations. You are strongly advised to remain well within the limits provided by this device to minimize the risk of DCS. You should consult a physician regarding your fitness before diving.

• This device can calculate decompression stop requirements. These calculations are at best an estimate of the real physiological decompression requirements. Dives requiring staged decompression are substantially more risky than dives that stay well within
  no-stop limits. Diving with rebreathers, diving with mixed gases, performing staged decompression dives, and diving in overhead environments greatly increase your risk while scuba diving.

• The transmitter uses sonar technology to communicate with paired devices underwater. Signals can be lost if there are large objects or obstructions between paired devices when diving in groups. Each diver should always use their own transmitter paired to their own dive computer to ensure better connectivity between the transmitter and dive computer.

• The dive computer can calculate your surface air consumption rate (SAC) and air time remaining (ATR). These calculations are an estimate and should not be relied on as the only source of information.

• If you have a pacemaker or other implantable medical device, consult your physician before you dive. Scuba diving creates physical stresses on the body, which may not be suitable for individuals with pacemakers and other implantable medical devices.

• Always use backup instruments, including a depth gauge, submersible pressure gauge, and timer or watch.
  You should have access to decompression tables when diving with this device.

• Use a wrench when installing the transmitter on your tank regulator. Do not overtighten. Do not use the transmitter housing to tighten the transmitter.

• Do not grip the regulator or the transmitter to move, carry, or adjust the air tank.

• Perform pre-dive safety checks, such as checking proper device function and settings, display function, battery level, tank pressure, and bubble checks to check hoses for leaks.

• Confirm the dive computer is receiving a signal from the transmitter prior to starting your dive. The pressure value and battery level should appear on the dive computer screen. Each diver is responsible for their own safety and tank pressure.

• Check your device regularly during a dive. If there is any apparent malfunction, terminate the dive immediately and safely return to the surface.

• If the dive computer receives no signal from the transmitter, the pressure value is replaced by “NO COMMS.” Check the position of the transmitter relative to the dive computer, and change the position as needed to acquire a signal. If a signal is not acquired, terminate the dive immediately and safely return to the surface.

• If a tank pressure warning or battery warning appears on the dive computer, terminate the dive immediately and safely return to the surface. Disregarding the alarm may result in serious injury or death.

• This device should not be shared between multiple users for diving purposes. Diver profiles are user-specific, and using another diver’s profile can result in misleading information that could lead to injury or death.

• For safety reasons, you should never dive alone. Dive with a designated buddy. You should also stay with others for an extended time after a dive, because the potential onset of decompression sickness (DCS) may be delayed or triggered by surface activities.

• This device is not intended for commercial or professional dive activities. It is for recreational purposes only. Commercial or professional dive activities can expose the user to extreme depths or conditions that increase the risk of DCS.

• Do not dive with gas if you have not personally verified its contents and input the analyzed value to the device. Failure to verify tank contents and input the appropriate gas values to the device will result in incorrect dive planning information and could result in serious injury or death.

• Diving with more than one gas mixture presents a much greater risk than diving with a single gas mixture. Mistakes related to the use of multiple gas mixtures may lead to serious injury or death.

• After analyzing your gas, always round down the result when inputting it to the device. For example, if the analyzed gas is 31.7% oxygen, input the gas as 31%. This buffer will result in more conservative and safer calculations.

• The transmitter is not an oxygen-cleaned product. Do not use the transmitter with anything greater than 40% oxygen.

• Diving with a partial pressure of oxygen (PO2) greater than 1.6, a central nervous system (CNS) oxygen toxicity exposure of 80% or greater, or daily oxygen tolerance units (OTU) of 300 or greater can be hazardous and could result in serious injury or death. Terminate the dive if you reach oxygen toxicity levels.

• Always ensure a safe ascent. A rapid ascent increases the risk of DCS.

• Disabling the deco lockout feature on the device can result in an increased risk of DCS, which can result in personal injury or death. Disable this feature at your own risk.

• Violating a required decompression stop may result in serious injury or death. Never ascend above the displayed decompression stop depth.

• Always perform a safety stop between 3 and 5 meters (9.8 and 16.4 feet) for 3 minutes, even if no decompression stop is required.

• The maximum operating depth (MOD) should not be exceeded. Disregarding the alarm may result in serious injury or death.

• The maximum operating pressure of the transmitter should not be exceeded.

• Traveling to a higher elevation, including air travel, can temporarily cause a change in the equilibrium of dissolved nitrogen in the body. Always acclimatize to new altitudes before and after diving, because failure to do so may result in personal injury or death.

Battery Warnings

A lithium-ion battery is used in this device. If these guidelines are not followed, batteries may experience a shortened life span or may present a risk of damage to the device, fire, chemical burn, electrolyte leak, and/or injury.

• Do not disassemble, modify, remanufacture, puncture or damage the device or batteries.
• Do not remove or attempt to remove the non-user-replaceable battery.
• Do not expose the device or batteries to fire, explosion, or another hazard.
