Proper Use
Caution Connection to a battery operated PC should only be
allowed by the end user.
Connection to a line powered device with an ITE Class II
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.
Accessory equipment connected to the monitor’s data interface must be
certified according to IEC Standard 950 for data-processing equipment or IEC
Standard 601-1 for electromedical equipment. All combinations of equipment
must be in compliance with IEC Standard 601-1-1 systems requirements.
Anyone who connects additional equipment to the signal inport port or signal
output port configures a medical system and is therefore responsible to ensure
that the system complies with the requirements of system standard IEC
Standard 601-1-1. If in doubt, consult Philips’ Response Center or you local
Philips representative.
