Battery Performance
Under power off or standby status, charging time of the battery from capacity 0 to 100% takes less
than 4 hours.
The continuous normal operation time of the system is not less than 1 hour when it is powered by
batteries.
The standby time of the system is not less than 24 hours when it is powered by batteries.
Power off the system if it will not be used for a long period of time (including storage/transportation
condition). Do not leave the system in standby status, otherwise the batteries will be discharged and
permanently damaged.
Battery Status Indicator
The battery status indicator is located in the bottom-right corner of the screen, indicating the battery
capacity.
• : Indicates the battery capacity is full.
• : Indicates the battery capacity is less than 20%.
• : Indicates the battery capacity is less than 10%.
• : Indicates the battery capacity is 0.
• : Indicates the battery is charging.
• : Indicates the battery is not installed.
• : Indicates the battery cannot be used. Please contact the Mindray service engineer.
3.2.3 Equipotential Terminal
The symbol represents the equipotential terminal that is used for balancing the protective earth
potentials between the system and other electrical equipment.
• Be sure to connect the equipotential wire before inserting the power plug
into the receptacle; be sure to pull out the power plug from the receptacle
before disconnecting the equipotential wire; otherwise electric shock may
result.
• When you connect another device to this system, you should use the
equipotential wire to connect each of equipotential terminals; otherwise
electric shock may result.
• Connect the earth cable before turning ON the system. Disconnect the
earth cable after turning OFF the system. Otherwise, electric shock may
result.
• DO NOT connect this system to outlets with the same circuit breakers and
fuses that control the current to devices such as life-support systems. If this
system malfunctions and generates overcurrent, or when there is an
instantaneous current at power ON, the circuit breakers and fuses of the
building’s supply circuit may be tripped.
