FAQ: General Information

How do I retrieve the unlock PIN of my Lynx?

If you have lost the unlock PIN of your Lynx and need to re-enter it (e.g. after a software update) you can retrieve it by logging in at Update Owner Info. You will need to provide your email address, the password you chose when registering your unit as well as your unit's serial number. You will then be able to see your PIN at the very top above your contact information.

What kind of batteries does the Lynx use and where can I get them?

All Lynxes can use 3.6V lithium 17335M disposable batteries as well as 3.2V lithium K2 rechargeable batteries.

You can purchase all those batteries at your local Liquivision Dealer. If you do not live near a Liquivision Dealer you can also order them from our webstore.

How long will my battery last?

The ER17335M batteries can provide up to 92 hours of dive time with your unit (low brightness, green font, battery used within a month of initial use), although 40-60 hours is more typical.

The life of your battery greatly depends on various factors such as the colours you choose, the brightness and refresh rate you set your display to, the water temperature etc. You can find a detailed overview on the factors that influence your battery life and how to optimize it on our battery information page.

How do I replace my unit's battery?

Please watch this instructional film on how to replace your unit's battery.

When should I replace the O-Ring that is around the battery cap?

Every time you replace your battery you should inspect the O-Ring as well. If the O-Ring looks dry or cracked you should replace it. You can find detailed instruction on how to replace your O-Ring in our instructonal film.

How can I update my unit's software if I do not have a PC Interface?

If you do not have a PC Interface but still want to update your software you have two options. You can either purchase a PC interface from your local Liquivision Dealer or from our webstore.

Alternatively you can go to your local Liquivision Dealer who will be able to update your unit for you. Please note that updating your unit may delete your dive log.

How deep can I dive my Liquivision Lynx?

The Lynx is CE tested and certified to a depth of 200 meters (656 feet). Any submersions or pressurizations beyond this depth will void the warranty.

What does the Lynx come with?

The Lynx comes with straps attached, as well as a bungee which you can install yourself. In addition to that you will find a quick start guide inside the box as well as two batteries for your unit (the unit only needs one battery, but we included two so you already have a spare one).

What are the main software features of the Lynx?

The Lynx has many convenient software features for recreational air and nitrox divers:

  • Revolutionary wireless Air Integration
    • Buddy Mode: Track a buddy's remaining air AND location (up to 10 divers at once)
    • Solo Mode: Track your own air consumption in sidemount
  • Digital compass
  • Dive Planner and Dive Simulator
  • Visual indicators of air-time remaining
  • Receive messages from the boat operator
  • Dive logging
  • Intuitive tap based navigation
How long is the warranty on the Lynx and what do I do if my unit breaks during the warranty period?

We offer a two year warranty on the Lynx. If you have problems with your unit you can contact your dealer who will be able to help you or you can contact us directly. If your unit is out of warranty you may still contact us and we might be able to help you and repair or replace your unit for a fee.

How does the Lynx compare to the X1 or the Xeo?

The Lynx is our full-color OLED, Air Integrated dive computer. The Xeo and the X1 on the other hand are technical trimix/ccr computers.
To get more information about the main features and differences of our units you can review our technical brochure and our recreational brochure.

FAQ: Lynx Troubleshooting

At the end of the installation process I see six "PASS" and one "FAIL" in the uploader.

When updating your unit's software you should either see seven "PASS" or six "PASS" and one "FAIL" at the end of the uploading process followed by "resetting your dive computer". In both cases your software will have installed properly and everything should work just fine.

To verify that the install succeeded pick up your unit, enter the main menu, and go to Preferences->Status, and the software version should be the same as the version that you tried to install (e.g. 1.08).

I am having trouble connecting my Lynx to my PC or Mac.

When connecting your unit to your Mac or your PC whether for updating the software or for downloading your dives please make sure that:

  • If you have a PC: The drivers and our software is installed.
    If you have a Mac: Our software is installed on your Mac (no need to install the drivers)
    You can find download and installation instructions here.
  • Your unit is aligned properly with your PC Interface
  • Your unit's battery is not empty
  • If it doesn't work immediately, rearrange the unit and the PC Interface a little and try again
I am having trouble updating my Lynx's software.

If you have trouble updating your unit's software please make sure you followed the steps outlined above. If you are still having trouble we compiled documents with detailed instructions for PC Owners and for Mac Owners.

I am having trouble downloading my dives.

When downloading your dives please make sure you follow the procedure outlined above under questions 2 and 3.

Also when initiating the download of your dives you have to tap into your unit and select "Connect to PC" in the main menu. After that place your unit on your desk and align it properly to the PC Interface. You have about 20 seconds from when you tapped "Connect to PC" to start the download process on your computer. If you take too long the operation will timeout and you will have to try again.

I am having trouble adjusting the time and date of my Lynx.

The Time/Date menu can be accessed from the Main Menu. Scroll down to "Time/Date" and tap left to enter.

If you are unable to adjust the time, date or year, or if the display does not match the time/date that you entered, you can reset the unit which will refresh the time/date scheme. You can reset the unit by either removing the battery for at least 8 hours, or connecting the Lynx to the computer with the PC Interface and pressing "Reset" in the Firmware Updater.

I'm diving with my T1 Transmitter, but I'm not getting any signal.

From the Main Menu, navigate down to "Air Integration". Within "Air Integration", select "Transmitter". Double-check that the Serial Number of the Transmitter you have entered matches your own Transmitter, by checking the sticker on the Transmitter. In order to be completely certain you are matched with the correct Transmitter, you can check the Serial Number that is engraved on the botttom of the Transmitter.

Next, you can run a Packet Test (Main Menu > Air Integration > Advanced > Packet Test). This Packet Test should receive "packets" from your Transmitter every 4 seconds, in addition to identifying the Serial Number of the Transmitter that is transmitting. If the packet test is not successful, but the Transmitter is chirping and flashing, inspect the 8 small holes on the back of the Lynx. If there is an orange light flashing, then the Lynx is successfully communicating with the Transmitter.

If you are not receiving any packets from the Transmitter, ensure you have a fresh battery in your Transmitter that is connected to a tank with a pressurized first stage. If the Transmitter is connected to a pressurized first stage, the Transmitter should now be transmitting, indicated by a green LED light flashing from the bottom, and a chirping noise every 4-5 seconds. If your Transmitter is still not transmitting, you may need to send it back to your dealer for repairs.

I'm diving with a properly functioning T1 Transmitter, but I sometimes lose signal.

Use of the T1 Transmitter requires some level of skill, and various factors can factor into maintaining a steady signal connection with the T1 Transmitter, including: dry suit use (air pockets can interfere with the signal), location of the Transmitter, body orientation, debris in the water, and more. We recommend carefully reading the User Manual, as we provide a detailed outline of how to get the best performance out of your T1 Transmitter and Lynx. The User Manual can be found here: http://liquivision.com/lynx_manuals.php

On my T1 Transmitter, there is a bit of play between the metal base and the clear plastic base.

This is normal. Early Transmitter units were designed to have a bit of play. The unit is sealed internally higher up, so this is not a weakness in water-tightness. The Transmitter has passed extreme stress tests and is meant to endure harsh conditions. This play will not will out the Transmitter. If you would like to remove the play, you can tighten the transmitter with a wrench instead of your hand, which will make the Transmitter fit tightly.

What if I want to attach my Transmitter to a High Pressure Hose?

It is possible to attach your Transmitter safely to a HP Hose. However, we recommend reading this first.

Why does my Transmitter keep transmitting even after I close the air valve on my tank?

After you close the valve on your tank, the Transmitter will still transmit, because it is sensing PSI in the first stage regulator. After you have depressurized your first stage, however, the Transmitter will continue to transmit for 10 minutes. This is called the Lost Man Signal, and is designed for emergency purposes, to locate a buddy for 10 minutes after he/she has run out of air.

It feels like I have to force my Transmitter to screw it into the tank. Is that normal?

The threads on our Transmitters are standard. However, each tank differs slightly. Some tanks may not provide a perfect fit. Some tanks may require you to screw the Transmitter in with some force. If you are uncomfortable doing this, you can send the Transmitter to us, and we will dye the threads to adjust how they fit.

There isn't room on my tank/first stage setup for the Transmitter. There are too many other hoses in the way.

We are currently working on an OmniSwivel adaptor that will enable flexibility for the Transmitter, so that it can fit onto a crowded first stage setup. Price and availability TBD.

Why can't I customize colours on my Lynx?

We have found that a high level of colour-customization leads to signal interruption with the ultrasonic technology of the Transmitter. In the end, we decided diver safety was more important than colour customization. However, we are looking into alternative colour schemes for future software updates that will not compromise signal reliability and strength.

My Lynx display is suddenly very dim and dark green. What should I do?

This is an emergency feature of the Lynx which kicks in when the battery is about to die. All you have to do is replace the dead battery with a fresh one, and your Lynx display will return to normal.

Are there any other screen layouts available?

There are 4 basic screen layouts available: Solo, Buddy, Group-4, and Group-9. However, because of the extra screen information on an Air Integrated computer, there is not much room for re-arranging these layouts. The pre-selected layouts will remain as they are for the near future.

Can I attach my Transmitter to a High Pressure hose?

Yes. We have heard feedback from a few divers that they successfully dove with their Transmitters attached to a High Pressure hose. However, as this was not the intended function of the Transmitter, we do not guarantee optimal signal reliability with this setup.
