Mindray P7-3T - Tip Deflection Control

TransducerControlsandInspection
12 Operator's Manual
3.1.2 TipDeectionControl
WARNING
●
If the deflection shows an unwanted amount of free play, do not use the
transducer. Contact the service organization to re-adjust the steering of the
transducer. In this way, the risk of "buckling" or "U-turning" of the transducer in
the esophagus is minimized.
●
To avoid damaging the transducer, do not deflect the transducer tip using finger
pressure directly on the tip, as this may permanently damage the internal control
wires.
