The code originates in the SYNC — respiratory gating section of the SYNC device — respiratory gating. Severity level A1 (Information / dialog).
Reported action: Check the respiratory gating system and the connection: sensor/belt position and tension, the sensor cable and its connector at the SYNC interface, and whether the monitor shows a usable respiratory waveform with the patient breathing normally. Restart the gating setup and repeat the acquisition; if a clean waveform is present and the code still appears, the fault is on the SYNC side — follow the SYNC device checks in the service manual and call service..
