Safety Considerations (Prism & Prism SE)
Read the following sections before using the Prism or Prism SE monitors. These cautions and
warnings are presented to both increase patient safety and prevent damage to the monitor.
WARNING: Shock hazard. Do not remove cover. There are NO user
serviceable parts. Contact qualified service personnel for all service
and repair.
Do not under any circumstances remove grounding conductor from
power plug. If there is any doubt about the integrity of the protective
earth conductor arrangement, operate monitor on internal battery
power until AC power supply protective conductor is fully functional.
To maintain patient electrical isolation, connect only to other
equipment with electronically isolated circuits.
WARNING: As with all electrical equipment, carefully route patient
cabling to reduce possibility of patient entanglement or strangulation.
WARNING: There is a potential fire hazard when used with oxygen-
emitting equipment, and danger of explosion when used near
flammable anesthetics.
WARNING: Do not use monitor during magnetic resonance imaging
(MRI). Induced current could potentially cause burns. The monitor
may affect MRI image and the MRI unit may affect the accuracy of the
monitor.
WARNING: To avoid shock hazard with RS-232 System
Interconnection, first consult IEC60601-1 for system interconnection
guidance. Specific requirements for system interconnection are
dependent upon device connected to the monitor and relative locations
of each device from patient, and relative location of connected device
to room containing the monitor. In all circumstances, the monitor
must be connected to a grounded AC power supply. The monitor is
referred to as an IEC 601/F device in the Summary of Situations
contained in IEC60601-1.
WARNING: When a remote display monitor is connected to the unit
via the VGA connector on side of unit, it is essential the remote
monitor is powered from a properly rated and approved isolation
transformer. This is required to meet earth leakage limits of 0.5 mA,
as per IEC60601-1, Cl. 19.3 for monitor.
WARNING: When connecting monitor to any other instrument, verify
proper operation before clinical use. Refer to the other instrument’s
operation manual for complete instructions.
WARNING: All input/output interfaces to the patient monitors must
be CSA601.1/UL2601-1, EN 60601-1 approved devices.
WARNING: Do not under any circumstance use replacement parts
and connect devices that are not approved by Medical Data
Electronics.
