11 TROUBLESHOOTING
Verify the Connection of the OptoWire
By default, The OptoWire pressure guidewire is delivered pre-connected to the FOIC.
Message:
No signal, check OptoWire connection
The Display Unit prompts this message when the OptoWire is not connected
to the FOIC or the proper optical connection is not established.
NOTE: The OptoMonitor 3 audio alert plays two different tones for optical
connection event.
• 2 Low tones – Lost connection of OptoWire/ Optical disconnection
occurred.
• 2 High tones – Successful connection of OptoWire/ Optical connection
occurred.
If Optical disconnection occurred:
1- Unlock the Handle locking mechanism and gently remove the OptoWire
pressure guidewire from its handle.
2- Gently reinsert the OptoWire pressure guidewire into its handle and
rotate the locking mechanism to the locked position.
OptoWire Zeroing Failed
The zero cannot be performed if pressure is varying (such as pulsatile blood pressure).
When the zero fails, the message “
Zero aborted
” appears on the Message window.
1- Ensure OptoWire is out of the patient.
2- In the SETTINGS screen, press the “OW Zero” button to perform a manual zero of the OptoWire.
3- If the pressure is stable (outside the patient) and the message persists, check all connections.
4- If the message still persists after verifying all connections, replace OptoWire.
OptoWire Zeroed Twice
The message “ Zero aborted, old value used ” is displayed when the OptoWire has been zeroed once
before, and a zero value is stored in the memory. The OptoWire is functional as intended.
NOTE:
The OptoWire is intended for single use. Once the FOIC connector and Gauge Factor Connector
have been inserted into the Handle Unit, the OptoWire can be used for a period of 24 hours.
