E0707 — Fend2/PREG Xmit fault — supply, enable, test circuit, noise or pulse parameter error
Philips CT error code, reported by the Ultrasound.
What E0707 means
On M2424A CT systems, status code E0707 indicates: Fend2/PREG Xmit fault — supply, enable, test circuit, noise or pulse parameter error. The code originates in the Scanner — Fend Xmit path section of the Ultrasound. Severity level alarm (Alarm — scanner error code).
Reported action: The data value logged with this code says which fault it is: 1000 = "[PREG] Xmit supply error" (also check Fend2); 2000 = "[PREG] Xmit enable error" (also check Fend2/Distr); 3000 = "[Fend2] Xmit test circuit error" (also check CLK); 4000 = "[Fend2] Xmit noise error"; 5000 through F000 = "[Fend2] Pulse parameter error" (also check Distr/A.MB). Read the data value before touching hardware — supply and enable faults are logged against PREG, the test circuit, noise and pulse parameter faults against Fend2..
Scanner error codes for the HP/Philips ultrasound system listed as "Model: M2424A" in the Hewlett-Packard Medical Products Group MPG Service Note M2424A-029 (Rev. C, 18 June 1999).
