    Protect your Observer from shocks, extreme heat and prolonged exposure to direct sunlight. If not in use, your Observer should be stored in a clean, dry environment at room temperature. The Observer can be wiped clean with a lightly moistened (warm water) cloth. Applying a mild soap to the area can clean stubborn stains or marks.

    10 seconds from the last pressing. 1.6 WATER RESISTANCE The Observer is water resistant up to 100m/330ft. However, it is not a diving instrument and therefore the buttons should not be operated (put in use) while underwater.
  • Page 10 The ON OFF Button Located on the bottom right of the Observer performs the following functions: • In the TIME Mode, the bottom field view can be scrolled displaying the calendar date, seconds, or dual time. • During the setup process, a short press causes the selected value to increase.

    In the calibration setting mode, scroll the barometric pressure value up or down until text “dEF” appears. This is the factory setting. Then exit by pressing [MODE]. 1.11 BATTERY REPLACEMENT The Observer operates on a three-volt lithium cell Type: CR 2032. The maximum life expectancy is approximately 12 months.
  • Page 13 To replace the battery: 1. On the backside of the Observer, insert a coin into the slot located on the battery compartment cover. 2. Turn the coin counterclockwise until it is aligned with the open position marker, or even slightly further for easy opening.

  • Page 14: Chapter 2 Time Mode

    After every battery replacement, it is necessary to calibrate the magnetic sensor. Refer to Chapter 5, Calibrating the Compass. CHAPTER 2 TIME MODE There are three time sub modes: time, chronometer and alarms. NOTE: These functions are accessible in the TIME mode, i.e. when the mode indictor is below TIME.

  • Page 15: Chronometer Sub Mode

    Once you determine the year, month and day, the Observer will supply the day of the week in the top field. Setup mode will automatically be released if left idle for more than one minute.

    1000 ft) 3.1 ALTIMETER-BAROMETER USE The Observer can be used as either a weather station or altimeter. This operating feature is chosen in the setup process while in the altimeter or the barometer mode. To toggle between these icon positions, hold the [Select]-button in for 2 seconds and then, press the [Quick] or [On Off]-button to lock in one of the functions.

  • Page 20: Setting The Altimeter

    The position of the icon indicates whether the Observer is being used as a weather station (BARO) or altimeter (ALTI). NOTE: This is different than moving between ALTI and BARO main modes. THIS IS IMPORTANT. The use indicator has to be in ALTI position, otherwise the altitude display is fixed.
  • Page 21 provided in the section below. If the Altitude is not known, you can set the sea level pressure in the Barometric mode. Refer to Chapter 4, Setting the Sea Level Pressure. Setting the Sea Level Pressure will adjust the altimeter to the current altitude within approximately ten meters or 30 ft.

  • Page 22: Logbook Sub Mode

    NOTE: You can return to main ALTI display by pressing [MODE] during any of the steps 1-9. Once you have set the reference altitude of the current location to the known altitude, the Observer will also correct the sea level pressure, and therefore, it will not be necessary for this function to be set.

    Observer will display the text “LOG” flashing in the bottom field. 3.3.2 To View in the Logbook Mode In the Altimeter mode, press the [SELECT] button once to enter this sub mode. The logbook mode features five screens. The first screen displays for 7 seconds. Thereafter, the screens will increment (2-5) displaying at four-second intervals.

    The third screen shows the number of laps (runs) accomplished during the current log- book. After the third display is shown, the Observer automatically returns to the main mode in which you were viewing.

    3.6 EFFECT OF AIR TEMPERATURE ON ALTITUDE MEASUREMENT The atmospheric pressure means the weight of air mass above the observer: at a higher altitude there is less air than at a lower altitude. The principle of an altimeter is to measure the different air pressure between different altitudes.

  • Page 28 The reference altitude is set at 3280 feet. At 9840 feet the altitude difference is 6560 feet and Observer shows 100 feet too much (-14 ºF * 6560 ft * 0.0011/ºF = -100 ft). Your actual altitude is thus 9740 ft.

    Press the [MODE] button until the mode indicator is directly below BARO. In the Barometric mode the fields display information as shown in Fig. 4.1: a) The top field displays the current temperature and barometric trend indicator; b) The middle field displays sea level pressure; c) The bottom field displays either the current time or the current absolute atmospheric pressure.

    NOTE: For successful calibration, it is important to hold the Observer level during the calibration process. This is simple to accomplish. For example, place the Observer on an over-turned drinking glass on a table. 5. Within a minute of completing a full circle, the Observer will inform you whether the cali-...

    Why is the altitude reading not changing even though I’m moving in a vertical direction? You are using the Observer as a barometer and the altitude is fixed. To change to the altimeter use, enter settings in the BARO or ALTI mode. The first thing that you can set is the choice...
  • Page 37 Observer do. Because the Observer measures ascent and descent based on changes in air pressure, it interprets these changes as vertical movement.
  • Page 38 - it will in either case give you the proper altitude reading providing the weather conditions have not changed. All Suunto Observers are temperature compensated within the range -5 to 140 ° F / - 20 to +60 ° C. Refer to Chapter 3, Effect of Air Temperature on Altitude Measurement.
  • Page 39 A natural way to alternate between Altimeter/Barometer Use during a hike is to use the Observer as altimeter when moving and as barometer when camping (no vertical movement expected). This way you will have more accurate information on both altitude and weather.
