PULSENSE | EPSON Sensing.

To determining the depth of sleep, use as the lowest pulse rate during sleep.
At the start of device use, a general value is used and it may not match the real feeling, but a stable sleep determination will be possible after about two weeks of use during sleep.
Sleep with a fever or after alcohol consumption causes higher pulse rate, and sleep determination may become difficult.

The zone value in the device does not display every zone value; instead, it only displays the fat burning zone

No specific sleep mode setting operation is necessary.
When you go to sleep during measurement, it performs the determination automatically based on body motion and pulse rate.
When sleep determination is unsuccessful, use the app's “Sleep setting”.
Sleep determination can be supported by setting up bedtime and waking time.
　* Please note that sleep outside of the set time is determined as “Relax”.

Following conditions may be determined as sleep when not sleeping
[Conditions determined as sleep]
1. Resting state with little body motion for a long time
2. Resting state while reading a book before bed, etc.
3. Resting state while reading a book after waking up, etc.
If the device has not been used for long enough, the device may misjudge due to insufficient learning.
Accuracy will improve through learning with more use.
Learning will also improve when worn during sleep.
If there is no difference in pulse rate when relaxing and sleeping (due to body characteristics), the device may detect this as sleep.

When there is activity after 5 minutes from waking (acceleration is read by the device), the device will detect as out of bed (10 minutes when sleep time is set)
The device can interpret as sleep if a relaxed state, such as reading, continues.

If there is no difference in pulse rate when relaxing and sleeping (due to body characteristics or drinking), the device may struggle to differentiate.
If sleeping and waking times are routine, you can help detection by setting sleep and wake times through the app's “Sleep Settings”.
When “Sleep Settings” is used, sleep outside of set times will not be recorded as sleep.
Instead it will detect as relaxed.
When sleep times are short (less than one hour), such as in an afternoon nap, the device will not detect sleep.
Instead it will detect this as relaxed.

There is no real set-up required for exercise mode.
The device will automatically detect activity during measurement.

Determination is performed from pulse rate and user's behaviour (exercise or resting state is determined by acceleration sensor).
Therefore, determination cannot be performed when pulse rate is not measured

Detection is based on relaxed pulse rates.
Since the device initially uses values based on the user's age, first-time use is not very accurate, but with more use, accuracy increases with learning.
Learning will also improve when worn during sleep.
Although accuracy will increase when worn during sleep, it will decrease with drinking.
When pulse rates are high, such as in sleep after drinking, the device may not detect sleep.
When sleep determination is unsuccessful, use the app's “Sleep setting”.
Sleep determination can be supported by setting up bedtime and waking time.
　* Please note that sleep outside of the set time is determined as “Relax”

No. The zone is automatically calculated; it’s based on your profile (age) and resting pulse rate.
Relaxed pulse rates are updated as pulse rates during sleep are measured, so the lower bound of the zone is automatically updated.

Fixed acceleration such as arm swing needs to be entered in the device in order to determine the exercise state.
Exercise with no arm swing such as exercise bike is not determined as an exercise, since acceleration is not entered in the device.
Therefore, it is determined as “Excite”.

When sleep settings are set in the app, times outside of the set times are detected as relaxed.
Sleep during movement such as being inside cars or trains may not be detected as sleep due to the movement.
