Low Battery Alert of the Sensors
Usually, the 9V batteries life of the sensors would last about 4-6 months.
The low battery alert for the sensors has five low battery modes:
1. When the sensor is at low battery, the watch gives an alarm once every two hours, the sensor will shut
down after three consecutive alarms.
• When an alert is given, the watch’s screen displays “No.000 low battery”.
• The digit represents the number of the sensor at low battery.
• if more than one sensors give the low battery alarms synchronously, only the last alarm is displayed. )

triggers the watch to give the first alarm. The status is as follows:

Low Battery indicates that the sensor’s battery has a low voltage (electricity), and may need to be
replaced.
3. The icons on the watch’s main interface are as follows:
