Do not under any circumstances remove the grounding conductor from the power
plug.
Do not use extension cords or adapters of any type. The power cord and plug must
be intact and undamaged.
If there is any doubt about the integrity of the protective earth conductor arrangement, operate the
oximeter on internal battery power until the AC power supply protective conductor is fully functional.
- Patient Isolation
To ensure patient electrical isolation, connect only to other equipment with electronically isolated
circuits.
Note: Do not connect to an electrical outlet controlled by a wall switch or dimmer.
- Cabling entanglement/strangulation
As with all medical equipment, carefully route patient cabling to reduce the possibility of patient
entanglement or strangulation.
WARNING
Do not place the monitor or external power supply in any position that might
cause it to fall on the patient. Do not lift the monitor by the power supply cord or
patient cable; use only the handle on the monitor.
- RS-232 & Alarms
RS-232 System Interconnection. Consult IEC-601-1-1 for system interconnection guidance. The specific
requirements for system interconnection are dependent upon the device connected to the MS board
pulse oximeter and the relative locations of each device from the patient, and the relative location of
the connected device to the medically used room containing the MS board pulse oximeter. In all
circumstance the MS board pulse oximeter must be connected to a grounded AC power supply. The MS
board pulse oximeter is referred to as an IEC 60601/F device in the summary of situations table
contained in IEC 60601-1-1.
Check alarm limits each time the MS board pulse oximeter is used to ensure that they are appropriate
for the patient being monitored.
