2 INTRODUCTION This User Guide explains the Suunto Core features, how they work, and how you access them. In addition, we have included examples of how you can use them in real life situations. Each main chapter explains a mode and its views. It also gives you information on how to set and use these views.
3 GENERAL SETTINGS Before you start to use your Suunto Core, it's a good idea to set the measurement units and general settings according to your preferences. General settings are changed in MENU 3.1 Adjusting strap length If you need to adjust the strap length of the metal strap, please contact your nearest watch store to get the needed adjustments correctly done for you.

Select a language from the list with [+] and [- Light]. 3.3.5 Activating button lock You can activate and deactivate the button lock by keeping [-Light] pressed down. When the button lock is activated, it is indicated with a lock symbol . NOTE: You can change views and use the backlight when the button lock is activated.
4 USING TIME MODE mode handles time measurement. TIME With [View] you can scroll through the following views: ● Date: current weekday and date ● Seconds: seconds as numbers ● Dual time: time in another time zone ● Sunrise and sunset : time of sunrise and sunset at a specific location ●...
4.1.1 Setting time you set the time. TIME To set the time: 1. In , select TIME-DATE 2. Change the hour, minute and second values with [+] and [- Light]. 4.1.2 Setting date you set the month, day and year. DATE To set the date: 1.
Now you always know the local time and you can quickly check what time it is at home. 4.1.4 Setting sunrise and sunset times you select a reference city that your Suunto Core uses to give you SUNRISE sunrise and sunset times.
To use the stopwatch: 1. In the mode, select the stopwatch view. TIME 2. Start, stop and restart the stopwatch with [Start Stop]. 3. Keep [+] pressed to reset the stopwatch. Possible real life situation: Timing the 100m dash Your friend is training for a running competition, and needs to know how long it takes him to run the 100 m dash.
You set the countdown timer to 8 minutes with your eggs in the pot and wait for the water to come to a boil. When the water boils, you engage the countdown timer. At the eight-minute point, your Suunto Core gives the alarm. Presto! Perfect 8-minute eggs.

Possible real life situation: Waking up in the morning You want to wake up early tomorrow morning. You set your Suunto Core alarm for 6:30 before you go to bed. The alarm wakes you up at 6:30 the next morning but you want to sleep for another 5 minutes.
5.1 How ALTI & BARO works To get the right readings from Suunto Core calculates altitude and sea level air pressure. Suunto Core constantly measures absolute air pressure. Based on this measurement and reference values, it calculates altitude or sea level air pressure.
Your Suunto Core will now give you the correct readings. To get the correct altitude readings, you need to enter the sea level air pressure reference value. The sea level air pressure reference value relevant to your location can be found in the weather section of the local newspaper or on the websites of national weather services.
Suunto Core are wrong. So, you hike to the nearest location shown on your topographic map for which a altitude reference value is provided. You correct your Suunto Core altitude reference value accordingly.
You’re hiking and take a break when you see a sign with the current altitude. You check your Suunto Core altitude reading and discover a small difference between the two numbers. You set the altitude reference value on your Suunto Core to match that of the sign.

to check upcoming weather conditions. The weather trend indicator is comprised of two lines forming an arrow. Each line represents a 3-hour period. The right line represents the last 3 hours. The left line represents the 3 hours prior to the last 3 hours. So the line can indicate 9 different patterns in the barometric trend.
Possible real life situation: Getting surprised by a storm while hiking You are hiking in a dense forest when your Suunto Core activates the storm alarm. The weather has taken a turn for the worse in the last 3 hours - the sky is getting dark.
When the profile is activated, you can access the following views ALTIMETER with [View]: ● Log recorder: records the altitude changes into logs ● Altitude difference measurer: measures the altitude difference from a set point ● Temperature: measures the current temperature ●...
Suunto Core. You start climbing, checking your altitude occasionally to see how far you are from the next check point. At some point you start to get tired.

is displayed when your altitude is the same as at the starting point. is displayed when your altitude is below the starting point. is displayed when you view how much you have ascended from the log start. is displayed when you view how much you have descended from the log start.
You’re going on another mountain hike. This time you want to record how much you ascend and descend so as to compare the figures with previous hikes. You set your Suunto Core to the ALTIMETER begin the hike. After the hike you stop your log recorder and reset it . Now you can compare it with your previous logs.
● Time: shows the current time ● Empty: no additional view NOTE: If you are wearing your Suunto Core on your wrist, you will need to take it off in order to get an accurate temperature reading because your body temperature will affect the initial reading.
You can start, stop and reset the altitude measurement while in the BAROMETER profile. Possible real life situation: Recording logs in the profile BAROMETER You are recording your altitude changes during a hike and decide to take a longer break. You switch to the profile.
NOTE: The AUTOMATIC activities require the BAROMETER you might be moving (e.g. surfing). In other words, in certain situations you need to choose a suitable profile manually. 5.8 Using depth meter profile You use the DEPTH METER and the maximum depth you reached during a snorkeling dive. The maximum depth of the device is 32.8 ft (10m).
5.8.1 Recording logs in depth meter profile The log recorder in the DEPTH METER in the profile, but instead of recording altitude it records the depth ALTIMETER of your snorkeling dives. To record logs in the DEPTH METER 1. In the ALTI &...
6 USING COMPASS MODE mode allows you to orient yourself in relation to magnetic North. COMPASS In the mode you can access the following views with [View]: COMPASS ● Time: shows the current time ● Cardinals: shows the current heading in cardinal directions ●...
Page 35
NOTE: If you notice deviations in the compass, you can recalibrate it by keeping it level and rotating it slowly clockwise until the north indicator shows a stable value.
6.1.2 Setting declination value Paper maps point to true North. Compasses, however, point to magnetic North a region above the Earth where the Earth’s magnetic fields pull. Because magnetic North and true North are not at the same location, you must set the declination on your compass.
6.2 Using compass When you are in the COMPASS rim of the display. These point towards North. The hairline at 12 o’clock shows your heading and functions as a compass direction arrow. The numerical value of your heading is shown in the center of the display. mode you can access the following views with [View]: COMPASS ●...

Lock/unlock the log with [Mode] Cancel with [View]. 7.3 Choosing recording interval You can choose the recording interval in You can choose between five recording intervals:...
Page 45
TIP: It is better to use a faster recording interval for short lasting activities with fast changes in altitude (e.g. downhill skiing). A slower recording interval is more suitable for long lasting activities with slower changes in altitude (e.g. hiking).
