WARNINGS
• Do not use the deflection brake on pediatric patients.
• The ability of a patient to swallow or accommodate the transducer should
be considered.
• You must consider any history of gastroesophageal diseases as well as the
possible effects of other therapies that the patient is undergoing. You must
also consider all gastroesophageal abnormalities or difficulty swallowing.
Handling the S8-3t Transducer
Because of its small size, the S8-3t transducer is a very delicate electronic
instrument. To avoid damaging the transducer, observe the following cautions:
CAUTIONS
• When wiping the distal tip of the S8-3t transducer, never apply excessive
force to the acoustic window. Gently wipe the tip with a moist cloth. Do
not squeeze the window or tip, because this may damage the transducer.
• Do not allow sharp objects, such as scissors, scalpels, or cauterizing knives,
to touch transducers or cables.
• Articulate the tip only with the controls; do not articulate it with your hand.
• Do not bend or crimp the gastroscope or cable.
• When handling any transducer, do not bump the transducer on hard
surfaces.
S8-3t 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 lower wheel on the transducer handle is for controlling the transducer tip
deflection. This wheel has a brake-on mode and a brake-off mode that allows it
to freewheel. With the brake on, the movement of the deflection wheel is
