健身應用程式
1. Podcast
support will be added via software update.
2. Amazfit Active Max can be used as a map browsing tool to import OSM map files.
The downloaded offline map must match your real location to be displayed, and a
route file must be imported for navigation – it's not possible to choose a point on the offline map for navigation. The shown straight line back to the start of a journey may not be a practical route to follow due to environmental factors; this is only intended to help you keep track of your position in relation to the start point of the journey. Navigation functions are only compatible with outdoor sports modes.

factors. So the actual result may differ from the laboratory data.

wrist, and keep your arm still for best results. SpO₂ alerts are sent if the detected rate is
too low compared to the preset value, which needs to be set in the Zepp App, at
a minimum of 80%. Movement, and environmental and physical characteristics can
affect speed and accuracy of monitoring and measurement. The 24-hour stress
level monitoring needs to be enabled on the watch or in the Zepp App. Alerts

15.According to the ISO 22810:2010 standard, the Amazfit Active Max achieves a
rating of 5 ATM, for a water-resistance of up to 50 meters, and is therefore
suitable for splashes, snow, showering, or swimming. It has passed third-party
testing conducted by TUV-SUD , and the report number is 68.189.25.00139.01 .
Remove the watch when taking a hot shower or trip to the sauna, since too much
steam can affect the seal and make it less water-resistant in future. Do not
wear the watch with a leather or metal strap when swimming - when preparing to
swim, change to a silicone strap or other suitable type. For more information,
please visit the support page at: support.amazfit.com

Walking, Outdoor Cycling, Pool Swimming, Rowing Machine, Elliptical. The
accuracy and sensitivity of the workout recognition feature varies from person
to person, and are related to the posture and proficiency of the user during
their workout. Short workout duration or frequent changes in posture may not
trigger the automatic recognition feature. When you are driving a car or taking
a bus, or taking part in other such activities, accidental recognition may be
triggered if these activities are particularly similar to the selected workout
mode. When you are conducting outdoor activities, if the GPS signal is poor or
the AGPS data information has not been synchronized with the mobile phone for
an extended period, these outdoor activities may be assessed as indoor
activities.
