This instrument must be serviced by an authorized dealer every second year or after 200 dives (whichever comes first). See chapter 6. PrEN 13319 PrEN 13319 "Diving accessories ­ Depth gauges and combined depth and time measuring devices ­ Functional and safety requirements, test methods" is a European diving depth gauge standard draft. The MOSQUITO is designed to comply with this draft standard. ISO 9001 SUUNTO Oy's Quality Assurance System is certified by Det Norske Veritas to be according to the ISO 9001 in all SUUNTO Oy's operations (Quality Certificate No. 96-HEL-AQ-220). SUUNTO Oy does not assume any responsibility for losses or claims by third parties, which may arise through the use of this device. Due to continuous product development, the MOSQUITO is subject to change without notice. 2 WARNING Read this manual. Carefully read this instruction manual in its entirety paying close attention to all warnings listed below, including chapter 1.1. "Safety Precautions". Make sure that you fully understand the use, displays and limitations of the dive computer because any confusion resulting from neglecting to follow this instruction manual or from improper use of this device may cause a diver to commit errors that may lead to serious injury or death. WARNING Not for professional use. Suunto dive computers are intended for recreational use only. The demands of commercial or professional diving may expose the diver to depths and exposures that tend to increase the risk of decompression illness (DCI). Therefore, Suunto strongly recommends that the device be not used for commercial or professional diving activity. WARNING Only divers trained in the proper use of scuba diving equipment should use a dive computer. No dive computer can replace the need for proper dive training. Insufficient or improper training may cause diver to commit errors that may lead to serious injury or death. 3 WARNING There is always a risk of decompression illness (DCI) for any dive profile even if you follow the dive plan prescribed by dive tables or a dive computer. No procedure, dive computer or dive table will prevent the possibility of DCI or oxygen toxicity. An individual's physiological make up can vary from day to day. The dive computer cannot account for these variations. You are strongly advised to remain well within the exposure limits provided by the instrument to minimize the risk of DCI. As an added measure of safety, you should consult a physician regarding your fitness before diving. WARNING Suunto strongly recommends that sport divers limit their maximum depth to 40 m [130 ft] or to the depth calculated by the computer based on the selected O2% and a maximum PO2 of 1.4 bar settings. WARNING Dives with required decompression stops are not recommended. You should ascend and begin decompression immediately when the dive computer shows you that a decompression stop is required. Note the blinking ASC TIME symbol and the upward pointing arrow. WARNING Use back-up instruments. Make sure that you use back-up instrumentation including a depth gauge, submersible pressure gauge, timer or watch, and have access to decompression tables whenever diving with a dive computer. 4 WARNING Perform pre-checks. Always activate and check the device before diving in order to ensure that all Liquid Crystal Display (LCD) segments are completely displayed, that the device has not run out of battery power, and that the oxygen, altitude and personal adjustments are correct. Also, exit the Data Transfer mode before diving, as the computer does not automatically revert to Dive mode from Data Transfer mode. WARNING You are advised not to fly any time the computer counts down the no-flying time. Always activate the computer to check the remaining no-fly time prior to flying. The computer goes into the stand-by display automatically 5 minutes after surfacing. Flying or traveling to a higher altitude within no-fly time can greatly increase the risk of DCI. Review the recommendations given by Diver's Alert Network (DAN) in chapter 3.2.3.4. "Flying After Diving". There can never be a flying after diving rule that is guaranteed to completely prevent decompression illness! WARNING The dive computer should never be traded or shared between users while it is in operation. Its information will not apply to someone who has not been wearing it throughout a dive or sequence of repetitive dives. Its dive profiles must match that of the user. If it is left on the surface during any dive, it will give inaccurate information for subsequent dives. No dive computer can take into account dives made without the computer. Thus any diving activity up to four days prior to initial use of the computer may cause misleading information and must be avoided. 5 WARNING Do not dive with a cylinder of enriched air if you have not personally verified its contents and entered the analyzed value into your dive computer. Failure to verify cylinder contents and enter the appropriate O2% into your dive computer will result in incorrect dive planning information. WARNING The dive computer will not accept fractional percentage values of oxygen concentration. Do not round up fractional percentages. For example, 31.8% oxygen should be entered as 31%. Rounding up will cause nitrogen percentages to be understated and will affect decompression calculations. If there is a desire to adjust the computer to provide more conservative calculations, use the personal adjustment feature to affect decompression calculations or reduce the PO2 setting to affect oxygen exposure. WARNING Set the correct Altitude Adjustment Mode when diving at altitudes greater than 300 m [1000 ft] the Altitude Adjustment feature must be correctly selected in order for the computer to calculate the decompression status. The dive computer is not intended for use at altitudes greater than 3000 m [10000 ft]. Failure to select the correct Altitude Adjustment setting or diving above the maximum altitude limit will result in erroneous dive and planning data. 6 WARNING Set the correct Personal Adjustment Mode. Whenever it is believed that factors that tend to increase the possibility of DCI exist, it is recommended that you use this option to make the calculations more conservative. Failure to select the correct Personal Adjustment Setting will result in erroneous dive and planning data. WARNING Freediving after scuba diving is not recommended. It is recommended to avoid freediving for at least two hours and not to exceed five meters [16 ft] after scuba diving depending on your diving activity. Suunto also recommends you to be trained in freediving technique and physiology before conducting breath holding dives. No dive computer can replace the need for proper dive training. Insufficient or improper training may cause diver to commit errors that may lead to serious injury or death. NOTE: Changing from AIR to EAN mode is possible at any time. Changing from EAN to AIR mode however requires you to wait until the no-flying time has counted down. FREE mode is accessible at any time. FREE mode is limited to 5 minutes, after which a warning is given. After 5+1 minutes the computer goes into error mode. 7 TABLE OF CONTENTS 1.
