    1. INTRODUCTION Congratulations on your choice of the FAVOR AIR dive computer. The FAVOR AIR is a compact and sophisticated dive instrument that will give you years of troublefree and joyful diving. The FAVOR AIR dive computer will provide you with important information that you will need during, between, and after your dives.

  • Page 6 When diving at higher altitudes (above 700 m/2300 ft), it is essential that the entered altitude mode, i.e. maximum altitude limit of the FAVOR AIR, exceeds or is equal to the altitude of the dive site. The altitude mode indicator must show either A1 or A2, depending on the altitude.

Therefore, the FAVOR...

  • Page 9: Getting Acquainted And Diving With The Favor Air

    You will find that the FAVOR AIR is easy to use and read. Each display shows only the data relevant to that specific diving situation. For example, while you are on a dive, surface interval data is irrelevant and therefore not shown.
  • Page 10 When submerged these contacts are automatically connected by the conductivity of the water. The FAVOR AIR is controlled on the surface with the COM (common), PLAN/ON and TIME/MODE contacts as follows: Activation: touch the PLAN/ON and COM contacts.

  • Page 11: Before Diving

    3.3 BEFORE DIVING 3.3.1 Activation, Prechecks and Battery Warning When deactivated the time display is always shown. In this mode the FAVOR AIR is ready for use and will activate if submerged. However, it is necessary to turn it on before diving to check the personal/altitude adjustment setting, battery power, cylinder pressure etc.
  • Page 12 - you have enough air for your planned dive. You should also check the pressure reading against your back-up pressure gauge. The FAVOR AIR is now ready for diving. If the FAVOR AIR is not taken on a dive after activation, it will automatically switch off to the time display after 10 minutes to conserve the battery power.

  • Page 13: Dive Planning

    If the battery symbol is displayed in the surface mode or if the display is faded or weak, the FAVOR AIR should not be used. It indicates that the battery is too low to operate the FAVOR AIR. If the low battery symbol appears during a dive, you should abort the dive and begin ascent to the surface.

    3.4 DIVING 3.4.1 Basic Dive Data The FAVOR AIR will remain in the SURFACE mode at depths less than 1.8 m [6 ft]. At depths greater than 1.8 m the FAVOR AIR will go into the DIVE mode. Each piece of information on the display is clearly marked. During a no-decompression...

  • Page 15: Cylinder Pressure Data

    The calculations of the remaining air time include a 35 bar [500 psi] safety buffer. This means that when the FAVOR AIR shows the air time to be zero, there is still about 35 bar [500 psi] pressure left in your cylinder depending on your air consumption rate. With a high consumption rate the limit will be close to 50 bar [725 PSI] and with a low rate close to 35 bar [500 PSI].

  • Page 16: Ascent Rate Indicator

    Low Air Pressure Warnings The FAVOR AIR will warn you with three audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar [725 psi]. The following three double beeps are heard when the cylinder pressure reaches 35 bar [500 psi] and the remaining air time reaches zero.

  • Page 17: Audible And Visual Alarms

    3m - 6m [10ft - 20ft] for 3 - 5 minutes. 3.4.4 Audible and Visual Alarms The FAVOR AIR features audible and visual alarms to alert you when you are approaching dangerous situations or to acknowledge certain commands given by you.

  • Page 18: Decompression Dives

    After this the FAVOR AIR will continue to provide subsequent interval and repetitive dive information. Rather than requiring you to make stops at fixed depths, the FAVOR AIR permits you to decompress within a range of depths.
  • Page 19 In this case, it will be more manageable to maintain an additional distance to the ceiling, to make sure that the waves do not lift you above the ceiling. SUUNTO recommends that decompression takes place deeper than 4 m [13 ft], even if the indicated ceiling is shallower.

  • Page 20: At The Surface

    NEVER LET THE CEILING DEPTH DESCEND DEEPER THAN 9 m [30 ft]! When the ceiling is deeper than 9 m [30 ft], a blinking error warning Er will appear and when the 12 m [39 ft] ceiling is reached the FAVOR AIR will go into a permanent error mode.

  • Page 21: Flying After Diving

    - The present cylinder pressure in bars [psi]. If you start a new dive after less than 10 minutes at the surface, the FAVOR AIR interprets this as a continuation of the previous dive. The DIVING display will return, the DIVE number will remain unchanged, and DIVE TIME will continue from where it left off.

  • Page 22: Personal Adjustment And High Altitude Dives

    - Following any dive that required a decompression stop, flying should be delayed for at least 24 hours, and if possible, for 48 hours. Suunto recommends that flying be avoided until all the DAN and UHMS guidelines and the FAVOR AIR wait to fly conditions are satisfied.

  • Page 23: Error Conditions

    When programming the FAVOR AIR for the correct altitude, the diver needs to select the correct altitude mode according to Table 3.2. As a result the FAVOR AIR adjusts its mathematical model according to the entered altitude, giving shorter no-decompression times at higher altitudes (Tables 6.1 and 6.2).
  • Page 24 9 m [30 ft] or the ASCent TIME is shorter than 63 minutes. If the ceiling descends to the depth of 12 m [39 ft] even momentarily the FAVOR AIR will enter the permanent ERROR MODE.

    All menu based modes can be deactivated by the RETURN command, i.e. by connecting all three contacts simultaneously, or by immersing the FAVOR AIR in water. Fig. 4.1 MENU The FAVOR AIR will scroll through the above displays.

    The blinking will stop and the other mode indicators will disappear. 5. The process is ended by the RETURN command, i.e. by connecting all three contacts at the same time. The FAVOR AIR will return to the surface mode. WARNING!

  • Page 28: Time And Date Setting

    SITE! 4.4 TIME AND DATE SETTING The current date and time is read by connecting the TIME/MODE and COM contacts for about two seconds, as described in Section 3.3.3, "Calendar Clock Function". Once the Time Setting mode is activated the principle when adjusting the clock is that: - the TIME/MODE and COM contacts scroll through the different displays, - the PLAN/ON and COM contacts change the values of the selected display.

  • Page 29: Maintenance

    Make sure that all salt crystals and sand particles have been flushed out of the console. At the end of a dive trip, the FAVOR AIR should be rinsed thoroughly and then dried with a soft towel.

  • Page 30: Assembly And Disassembly

    DO NOT use the FAVOR AIR if you detect any moisture or water inside. CAUTION! - do not use compressed air to blow water off the unit - do not use solvents or other cleaning fluids that might cause damage - do not test or use the FAVOR AIR in pressurized air.

The FAVOR AIR is now ready for use.
  • Page 34 ENTIRE OWNER'S MANUAL! The FAVOR AIR must be activated before diving and operated correctly to provide accurate and correct information. No-Decompression Limits The no-decompression limits displayed by the FAVOR AIR upon activation are for most dives to a single depth slightly more conservative than those permitted by the U.S. Navy tables, Tables 6.1-2.

    Before high altitude diving the FAVOR AIR must be set to high altitude diving mode to take this into account. The maximum partial pressures of nitrogen allowed by the mathematical model of the FAVOR AIR are reduced according to the lower ambient pressure.
