Fault Description
Simple Remedy
■ Tag at room temperature, life time can reach 5
years.After 5 years, tag batter is low, should be
Low battery
replaced.If tag life less than 5 years and battery is
low, please contact customer service.
■To power the device, tag LED working.Tag monitoring
device current value is zero all the time.Tag status
Not properly monitoring
info does not appear low battery,but can’t monitoring
equipment current
any current.In this case,tag inside circuit failure,
please contact customer service.
Routine Maintenance
■Try to avoid the use of tags under wet conditions
