If a system reboot cannot restore the wireless connection, use a third-party trigger device that supports 50ohm BNC interface and TTL output pulse with 100ms width, and connect to the system's external trigger port on the front cover. The port can be located according to Section 3.4.7 of the System Operator Manual.\na) Make sure ECG and respiratory square pulse signals are displayed on the console monitor;\nb) Perform gated reconstruction based on the ECG and respiratory trigger pulses.\n3. For further questions, please contact your recalling firm service engineer or call the Customer Contact Center's 24-hour hotline at (855) 221-1552 (toll-free) or (832) 699-2799 (direct).\n4. Notify all your internal users of the PET/CT system, using this letter.\n5.
