S7-3t TEE Controls

The transducer handle is designed for one-hand operation. Normally, you should operate the
transducer handle with your left hand. The thumb, first, and second fingers control the
deflection and the array rotation control wheels.
The smaller wheel on the transducer handle is for controlling the transducer tip deflection. This
wheel has a locked mode and a freewheeling mode. In the locked mode, the movement of the
deflection wheel is restrained to allow you to hold the tip in a certain position. A metallic ring
around the body of the handle, which clicks on and off, controls the lock.
The larger wheel on top is for rotating the imaging array. The array can be rotated continuously
from 0 degrees (transversal plane) through 90 degrees (longitudinal plane) to 180 degrees
(transversal plane, left/right inverted).
WARNING
Verify that the maximum deflection of the tip is 120 degrees up and 90 degrees down. If the
up/down deflection shows an unwanted amount of free play or exceeds the maximal
deflection angles, do not use the transducer. Contact Philips to readjust the steering of the
transducer. Ensuring proper deflection limits minimizes the risk of the tip folding over in the
esophagus.
WARNING
To protect the patient and the transducer, straighten the tip of the transducer and unlock the
deflection control when inserting or withdrawing the transducer. On the S7-3t, the tip is
straight when the white line on the control wheel is aligned along the shaft of the transducer
handle.
