The operating time of a battery directly reflects its performance. If the operating time of a 
battery is noticeably shorter than that stated in the specifications, contact your Mindray 
service personnel. 
 
NOTE 
  The battery may be damaged or may have malfunctioned if it only operates for 
a short time after being fully charged. The operating time depends on the 
configuration and operation. For example, measuring NIBP more frequently 
also shortens the operating time. 
  Replace a battery that has visual signs of damage or no longer holds a charge. 
Remove the old battery from the monitor and recycle it according to local laws.
