20. it is still hard for your unit to judge how much dive time is left Dive time on the LYNX will be greatly affected by user settings such as screen brightness Once the battery voltage starts to drop it drops fast Your LYNX or Transmitter will stop functioning entirely once the voltage drops below a certain level For all these reason it is important to pay attention to the Yellow battery indication it means there is really very little time left Basic Rules For Optimizing Battery Life in your LYNX The battery life is significantly affected by the Air Integration mode you select and the brightness setting of your display Aur Integration OTT will give you the longest LYNX battery life Air Integration Solo mode will give you medium LYNX battery life Air Integration Buddy Group 4 Group 9 and Tec Solo modes will give you the shortest battery life Thus you should ideally use the best Air Integration mode for your needs on a given dive If for example you typically dive in Buddy mode with a Buddy who owns a Liquivision Tank Transmitter and then dive once with another Buddy who does not have a Liquivision Tank Transmitter rather than dive in Buddy mode with your Buddy s transmitter showing No Signal you should switch your Air Integration mode to Solo This will stop your LYNX from looking for your Buddy s tank signal and save battery life Liquivison Products Inc 13

70. 1 Location transmitters The ability to receive ultrasonic signals as against the industry standard radio frequency RF signals vastly increases the LYNX AI range typical RF based air integrated dive computers offer a maximum range of 1 5m 6ft while the LYNX AI offers a range of up to 100m 330ft The LYNX AI range can be affected by a large number of factors which we will discuss later Nevertheless it is fair to say that in the vast majority of open water conditions the LYNX range is greater than the safe distance between you and your Buddy or a Dive Master and his her Group Also ultrasonic transmission is more stable than RF it is not subject to interference from typical sources such as HID lights camera strobes or scooters DPVs The LYNX s huge range opens up a whole set of new dive computer applications While the limited range of RF products made them only relevant to monitor your own tank the LYNX allows you to monitor your Buddy s Tank Transmitter or up to 9 of your Group s Tank Transmitters within the safe distance The safe distance is defined as the distance that you can cover in an out of air situation on a full exhale and still make it in time to breathe safely of your Buddy s regulator for most people this should not be more than 6m 20ft The LYNX can also monitor an L1 Location Transmitter a Transmitter that is activated without tank pressure that can be used to mark a specific location
71. 2 Inspect the T1 U 2 Transmitter O Ring Your Tank Transmitter has a Viton O Ring on the metal base where it screws into the first stage regulator The Viton O Ring is compatible with Nitrox and O2 while regular O Rings are not Always inspect this O Ring prior to screwing in your first stage It should be clean and well lubricated with silicone O Ring grease If there is dirt damage or cracking it should be cleaned or replaced How to replace O Ring You can obtain replacement O Rings from Liquivision Otherwise they are available online from suppliers like McMaster Carr details below Viton T1 metal base O Ring specs T1 metal base with Fluoroelastomer AS568A 012 ID 3 8 OD 1 2 Search for item 9464K17 on www mcmaster com Viton ORing 3 Screw the T1 U 2 Transmitter into the HP Port You can tighten it quite firmly by hand and this should be sufficient You can use a wrench if you like It is compatible with a 34 wrench 18 9mm 4 T1 U 2 Transmitter First Stage Compatibility The T1 Transmitter is slightly larger than existing radio frequency transmitters However it has been carefully designed to fit in almost every possible Ist stage hose configuration If you find that the Liquivison Products Inc 25 Manual 1 6 Lynx 1 18 US 1 11 U 2 3 06 LIQUIVISION LYNX Air Integrated Dive Computer User Manual transmitter 1s colliding with another hose it 1s usually sufficient to first disconnect the other hose then

73. 5 Manual 1 6 Lynx 1 18 US 1 11 U 2 3 06 LIQUIVISION LYNX Air Integrated Dive Computer User Manual The other important thing is to choose the lowest screen brightness setting you need for your dive The LYNX has an Auto Dim feature where the unit uses your chosen brightness setting on the surface and slowly reduces brightness to Low as you descend to a selected depth Basic Rules For Optimizing Battery Life in your Tank or Location Transmitter Your Tank Transmitter is turned on when your first stage regulator is pressurized and it senses more than 200 PSI 14 BAR of tank pressure It keeps transmitting until A you de pressurize your first stage regulator or B the tank pressure drops below 100 PSI 7BAR for more than 10 minutes To preserve Tank Transmitter battery life you should always close your tank valve after your dive and de pressurize your first stage regulator To preserve Location Transmitter battery life always turn your L1 OTT after a dive by unscrewing the top slightly so the battery stops connecting Detailed Rules For Optimizing Battery Life in your LYNX 1 Air Integration Mode The Air Integration mode has the biggest impact on battery life as it means the LYNX is constantly checking for data packets from one or more transmitters For this reason it is important to use the minimum Air Integration mode you need for a given dive The most battery friendly AI mode is Off followed by Solo then by
74. Buddy Group 4 and Group 9 and Tec Solo So if you don t need to monitor tank pressure on your next dive turn AI Off entirely If you only need to monitor your own tank but not your Buddy s switch from Buddy mode to Solo mode If you are just diving with your Buddy and not a Group switch from Group to Buddy mode 2 Brightness Brightness has the second effect on battery life As a general rule NORMAL brightness gives you HALF the battery life of LOW brightness The best way to optimize battery life is the Auto Dim feature 3 Refresh rate The refresh rate changes how fast information is updated on the screen It has two settings Normal and Fast If you can use Normal and you don t notice anything that is the best choice If you use Normal and you find that you can see the screen flickering when you move the unit then select Fast Also if you plan on taking any pictures or video of the LYNX select Fast The Fast refresh rate burns about 20 more battery power than Normal So battery life on Fast is reduced by about 20 4 Display layout in Gauge Mode only The display mode Standard Alternate Simple Large has a small effect on battery life Simple burns the least power Alternate burns 10 15 more than simple Standard burns 10 more than alternate 5 Water temperature Diving in cold water water temperature below 12 C 54 F shortens the life of your batt
