KVO may be stopped at any time by selecting the KVO button after KVO is initiated (illuminated in blue) or by

NOTE: Other actions that disarm the injector, such as syringe removal, pressing the Disarm button, and injection
stall will also stop KVO.
NOTE: If an occlusion occurs during KVO, the system will detect the condition after 4 or less KVO boluses fail to be
delivered. (The occlusion will be detected after 1 minute or less if the KVO interval is set to 15 seconds or
after 5 minutes or less if the KVO interval is set to 75 seconds.) Refer to
