If you stray too far off from the route while using altitude navigation, your watch will give you
an Off route message in the altitude profile display. If you see this message, scroll to the
route navigation display to get back on track before continuing with altitude navigation.
3.31. Sleep tracking
A good night's sleep is important for a healthy mind and body. You can use your watch to
track your sleep and follow how much sleep you are getting on average.
When you wear your watch to bed, Suunto Spartan Ultra tracks your sleep based on
accelerometer data.
To track sleep:
1. Go to your watch settings, scroll down to SLEEP and press the middle button.
2. Toggle on SLEEP TRACKING.
3. Set the times for going to bed and waking up according to your normal sleep schedule.
The last step defines your bedtime. Your watch uses that period to determine when you are
sleeping (during your bedtime) and reporting all sleep as one session. If you get up for a drink
of water during the night, for example, your watch still counts any sleep after that as the same
session.
NOTE: If you go to bed before your bedtime and also wake up after your bedtime, your
watch does not count that as a sleep session. You should set your bedtime according to the
earliest you may go to bed and the latest you may wake up.
Once you have enabled sleep tracking, you can also set your sleep target. A typical adult
needs between 7 and 9 hours of sleep per day, though your ideal amount of sleep may vary
from the norms.
Sleep trends
When you wake up, you are greeted with a summary of your sleep. The summary includes, for
example, the total duration of your sleep, as well as the estimated time you were awake
(moving around) and the time you were in deep sleep (no movement).
In addition to the sleep summary, you can follow your overall sleep trend with the sleep
insight. From the watch face, press the lower right button until you see the SLEEP display. The
first view shows your last sleep compared to your sleep target.
