1.7.4 General Warnings
WARNING
Make sure to inspect the equipment before use according to the
procedures provided in this manual to avoid unexpected accidents and
to take full advantage of the equipment’s capabilities. If the inspection
result shows any abnormality, do not use the same equipment.
This product is an ultrasonic endoscope for the upper digestive tract.
It is intended for the observation and diagnosis of the esophagus,
stomach and duodenum, and for the observation, diagnosis and
endoscopic treatment of submucosal and peripheral organs. Never
use this product for any other purposes. It may cause severe harm
to patient and/or end-users.This product is not intended for use on
children and infants.
Do not use this product outside the specified operating environment.
Otherwise, it can cause malfunction or failure.
CAUTION
Do not use this product using maximum light intensity from the
light source. Using the ALC (Automatic Light Control) mode is
recommended. Refer to the manual of the light source for the ALC
mode. When this product projects light at the maximum brightness for
2-3 minutes, temperature at the distal end may exceed 41°C. If the
surface temperature exceeds 41°C, thermal injury to the patient may
occur.
Turn off the lamp and stop the transmission of ultrasonic waves (freeze
the ultrasonic processor) except during a procedure, inspection, etc.,
when necessary. If the lamp is left on, the distal end may become
hot, causing burn injury to the operator, assistant or patient. Turn on
the lamp and transmit ultrasonic waves immediately before starting a
procedure.
When turning off the processor, also turn off the light source. If the light
source remains on after turning off the processor, the ALC (automatic
light control) does not function and the maximum amount of light
is emitted. As a result, the distal end of ultrasonic endoscope may
become hot, causing burn injury to the operator, assistant or patient.
