module with the device while removing
the battery.
WARNING
• Only use the specified central charger to charge to the lithium-ion bat-
teries designated by Mindray.
• Only use the approved power cord with the grounded mains plug to
firmly connect the central charger to a grounded AC mains socket. Never
refit the mains plug to fit an ungrounded AC mains socket.
• Do not use the Multiple Portable Socket Outlets (MPSO) or AC mains
extension cords. Use an IEC 60601-1 approved isolation / separation
transformer, otherwise, it may result in leakage current. Insure that the
sum of the individual ground leakage currents does not exceed the
allowable limits.
• Do not place any shield object (such as cloth or paper) to cover the cen-
tral charger or batteries, and keep ventilated while charging the lithium-
ion batteries.
• Do not connect other devices to the power supply system.
• Do not use the central charger to charge the lithium-ion batteries in high
temperature above 40°C.
