4. GENERAL PRECAUTIONS Federal (U.S.A.) law restricts this device to sale by or on the order of a physician. PressureWire® Receiver is only intended for use as an interface between PressureWire® and a compatible cathlab recording system. PressureWire® Receiver shall only be used with monitor cable approved by Radi Medical Systems. Before using PressureWire® Receiver refer to instructions for use supplied with PressureWire® for warnings, precautions, contraindications and instructions for use. Make sure PressureWire® Receiver is connected to intended PressureWire® and not to adjacent or previously used PressureWire® units. The PressureWire® receiver housing is protected against the effects of a discharge of a cardiac defibrillator. Handle and dispose of PressureWire® Receiver in accordance with medical practice and applicable local, state and federal laws and regulations.
5. INSTALLATION 5.1 Open the PressureWire® Receiver package and use the enclosed mounting bracket to fasten PressureWire® Receiver on or near cathlab table. At delivery the mounting bracket is assembled for pole mounting. If mounting on the table rail is desirable, disassemble the mounting bracket and reassemble according to the picture below.
If PressureWire® Receiver is used in a sterile environment it is recommended to cover it in a sterile plastic bag or under a plastic sheet. 5.2 Connect PressureWire® Receiver to one available invasive blood pressure channel on the cathlab hemodynamic recording system using the monitor cable supplied by Radi Medical Systems. 5
NOTE: Refer to section Technical Specification for compatibility with hemodynamic recording systems. NOTE: Radio range is reduced by objects and walls, keep transmitter and receiver in line of sight wherever possible. CAUTION: PressureWire® Receiver is powered by the excitation voltage from the invasive blood pressure channel. Therefore the cathlab hemodynamic recording system must be powered in order for PressureWire® Receiver to be activated. On some cathlab systems the pressure channels must also be activated and zeroed before the excitation is available.
Refer to instructions for use for the cathlab hemodynamic recording system for correct handling instructions. 5.3 A steady yellow light and a short beep on PressureWire® Receiver indicate that it is successfully connected and powered. 5.4 Zero pressure channel on the cathlab hemodynamic recording system.
6. PREPARATION FOR USE 6.1 If necessary, verify balance between PressureWire® Receiver and cathlab recording system, see chapter “Balance PressureWire® Receiver and cathlab recording system” below. 6.2 Activate the receiver by pressing the CONNECT button. The receiver is now ready to connect to PressureWire® transmitter (during 60s), indicated by blinking green light on the receiver. 6.3 Turn on the PressureWire® transmitter. PressureWire® will now calibrate and connect to the receiver. Refer to Instructions for use for PressureWire® Aeris for correct handling before calibration. 6.4 When the receiver is successfully connected to the transmitter the CONNECT button indicators changes to steady green light and a double beep is heard. - If a connection is not established and the green light on the receiver is still blinking, restart the transmitter by turning it off and then on again. - If a connection is not established within 60s the receiver returns to standby mode, indicated by a yellow light and a long beep. Reactivate PressureWire® Receiver by pressing the CONNECT button, then restart the transmitter by turning it off and then on again. - Refer to the table below for other light indicators. 6.5 After calibration, confirm that the pressure reading on the cathlab monitor is zero; re-zero the cathlab pressure channel if necessary. PressureWire® is now ready for use. 6
7. DIRECTIONS FOR USE NORMAL OPERATION
After successful connection to the PressureWire® transmitter, pressure is received by PressureWire® Receiver and converted for the cathlab hemodynamic recording system. ADJUST PRESSURE OFFSET (EQUALIZATION) To remove any residual pressure difference between aortic and PressureWire® pressure use the plus (+) and minus (–) buttons on the PressureWire® Receiver. To increase PressureWire® offset, in steps of 1 mmHg, press the plus (+) button. The plus (+) indicator (F) is lit as long as there is a positive pressure offset. To decrease PressureWire® offset, in steps of 1 mmHg, press the minus (-) button. The minus (-) indicator (F) is lit as long as there is a negative pressure offset. Alternatively, the equalization function on the cathlab recording system can be used to remove pressure offset. Refer to the Instructions for use for the cathlab recording system. NOTE: Before equalization, the height of the aortic pressure transducer should be aligned to heart level. If the ratio PressureWire®/Aortic pressure after height alignment is higher than 1.1 or below 0.9 it is recommended to take out PressureWire®, place it in the packaging coil, flush and then recalibrate according to PressureWire® Aeris Instructions for use, before adjusting pressure offset. BALANCE PRESSUREWIRE® RECEIVER AND CATHLAB RECORDING SYSTEM
It is recommended to daily verify that the pressure output from PressureWire® Receiver is in balance with the pressure displayed on the cathlab recording system. To provide reference pressure output levels to the cathlab recording system, enter Refout mode by pressing and holding the CONNECT button >3s. When Refout mode is activated, the plus (+) and minus (-) indicators (F) are lit. To increase/decrease pressure reference output level press plus (+) / minus (-) buttons. Pressure output level changes according to 0, 20, 40, 100, 200 mmHg, indicated by the function light indicators, see picture.

Field strengths from fixed RF transmitters, as determined by an electromagnetic site surveya, should be less than the compliance level in each frequency rangeb. Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1: At 80 MHz and 800MHz, the higher frequency range applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the PressureWire® system is used exceeds the applicable RF compliance level above, the PressureWire® system should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the PressureWire® system. b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m. 1) No mains power input

RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF COMMUNICATIONS EQUIPMENT AND THE PRESSUREWIRE® SYSTEM
The PressureWire® system is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the PressureWire® system can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the PressureWire® system as recommended below, according to the maximum output power of the communications equipment.
