  • Page 27: Charging And Replacement Of Battery

    Charging and Replacement of Battery During the long-term storage of the device, the battery may be too low due to the self-discharge of the lithium battery and the device cannot be turned on. This is a normal phenomenon. Please use the attached adapter to pre-charge the device for 0.5 to 1 hour (d epending on the storage time) before turning it on.
  • Page 28 Note To avoid overheating of the battery during charging, the ambient temperature must not exceed the allowable value given in the technical specifications. Replacement of Lithium Battery Generally, the battery does not need to be replaced. However, when necessary, it can only be replaced by qualified personnel, and only lithium batteries of the same specification can be used.
