[. . . ] User manual Bedienungsanleitung Manuel d'utilisation Manuale d'uso Instrucciones para el uso Handleiding Aladin TEC 2G Nederlands Español Italiano Français Deutsch English Safety considerations You must carefully read and understand this entire manual before using your Aladin TEC 2G. WARNING Diving has many inherent risks. Even if you follow the instructions of this manual in a careful manner, it is still possible that you may be seriously injured or die from decompression sickness, oxygen toxicity or some other inherent risk of scuba with Nitrox or compressed air. Unless you are fully aware of these risks and are willing to personally accept and assume responsibility for those risks, do not use Aladin TEC 2G. Guidelines for the use of Aladin TEC G: The following guidelines for using Aladin TEC 2G are derived from the latest medical research and the recommendations of the American Academy of Underwater Sciences for diving with diving computers. Following these guidelines will greatly increase your safety while diving, but cannot guarantee that decompression sickness or oxygen toxicity will not occur. [. . . ] If the computer detects a sufficient increase in altitude, it switches on automatically and indicates the new altitude range (1-4) and the desaturation time. Desaturation time indicated at this moment refers to adaptation time at this altitude. If the dive starts within this adaptation time, Aladin treats it as a repetitive dive, since the body is offgassing. Altitude is divided into five ranges, which are influenced by barometric pressure. If a mountain lake is reached, the altitude range is indicated at the surface (time of day display), in the logbook and in the dive planner by a stylised mountain and the current altitude range. Sea level to an altitude of approximately 1000m (3300ft) is not indicated. diagram, you can see the No deco data approximate breakdown 610mbar gauge mode 4000m 8. 85psi of the altitude ranges: 13120ft 3000m 9840ft 2000m 6560ft 725mbar 10. 51psi 815mbar 11. 82psi 905mbar 13. 12psi Altitude ranges 1000m 3280ft 0m 6. 3 Prohibited altitude WARNING Ascent to altitude range 3 and 4 prohibited. Max allowed altitude: 2650m (8694ft). Aladin shows via flashing altitude segments while at the surface to which altitude the diver may not rise. Max altitude: 850m 2790ft 1650m 5413ft 2650m 8694ft 4000m 13120ft The ascent prohibition can also be displayed together with an altitude range: Example: You are at 1200m (3937ft) (altitude range 1) and you may ascend to range 2 only (2650m / 8694ft). You may not rise to the altitude range 3 or 4. WARNING If an ascent to a prohibited altitude is detected, an audible alarm goes off for 1 minute (patent pending). Descend to a lower altitude. 6. 4 Decompression dives in mountain lakes In order to assure optimal decompression even at higher altitudes, the 3m (10ft) decompression stage is divided into a 4m (13ft) stage and a 2m (7ft) stage in altitude ranges 1, 2 and 3. The prescribed decompression stop depths are, in sequence, 2m / 4m / 6m / 9m. . . (7ft / 13ft / 20ft / 30ft. . . ). DEPTH DIVE TIME Dive at altitude range 4: · no deco data (gauge mode) III UWATEC Aladin TEC 2G If atmospheric pressure is below 620mbar (8. 99psi) (altitude higher than 4100m / 13450ft above sea level), Aladin switches automatically to gauge mode and no decompression data is calculated and displayed. In addition, the dive planner is not available anymore. 29 English IV Gauge mode WARNING In gauge mode ALL audible and visual alarms and attention messages are turned off. In gauge mode Aladin will display depth, dive time and max depth. By pressing you can scroll from the max depth to the temperature, to the average depth, to the time of day and back to the max depth. Gauge mode does not support the calculation of no-stop time or the supervision of decompression. The settings for the gas mixture, MOD and microbubble level cannot be set and the dive planner cannot be selected. Switching the gauge mode on and off Gauge mode can be switched on and off at the surface, when there is no desaturation and no-dive in gauge mode has been made in the last 48 hours. WARNING · Dives in gauge mode are performed at your own risk!· After diving in gauge mode you must wait for at least 48 hours before using a decompression computer. After diving in gauge mode, Aladin can not be used as dive computer for 48 hours. From the time of day display push "on" or "off" are displayed. (If Aladin shows " ­ ­ ­ " the gauge mode cannot be switched "on" or "off". Aladin shows " ­ ­ ­ " for 48 hours after a dive in gauge mode and as long as there is remaining desaturation after a dive in computer mode. ) 2. [. . . ] Make sure that the new o-ring is in perfect condition, and that o-ring, o-ring groove and the sealing surfaces are free of dust and dirt. Fit the o-ring in the o-ring groove of the battery cap. WARNING WARNING 7. This o-ring is Teflon coated and does not require additional lubrication. Do not lubricate the o-ring as the lubricant will chemically attack the battery cap. WARNING 9. [. . . ]
