Notes:
 Charging temperature (surrounding temperature): 0~35℃. If the
temperature exceeds 35 ℃, the device may stop charging.
 Operating temperature (surrounding temperature): 0~40 ℃. If
the temperature exceeds 40 ℃, the device may power off.
 It is recommended NOT to charge and use the device at the
same time.
 It is recommended to use the device in an open space with
better coverage and avoid multiple walls or metal materials
around the device.
 If the device operates in a poor coverage area, the device will
heat up due to higher transmitting power. Thus, it is
recommended to use the device in an adequately vented
environment to prevent the device from overheating.
 When the device operates under poor coverage conditions, the
top cover may be hot. Please avoid touching the cover.
