power supply is acceptable provided it passes all 60601-1-1
tests without a problem.
If there is a line powered device with a Class I power
supply, such as a line powered PC or a laser printer in the
system, there must be either optical isolation of the data
cable or the Class I devices must have isolation
transformers.
If you connect the monitor to any instrument, verify proper operation before
clinical use. Refer to the other device's manual for full instructions.
