12.2 If the Buzzer Sounds

<If the state in which the pressure inside the channel is exceeded +8.2 kPa continues for 5 seconds>
< If the pressure does not reach "+5.6 kPa" within 60 seconds after starting air feed>
<If the state in which the pressure inside the channel cannot be maintained at +5.6 kPa continues for 40 seconds or
longer>

If any of the following conditions occurs, it is considered as an occurrence of an
abnormality, which makes the PB-30 buzzer sound.
• If the state in which the pressure inside the channel is exceeded +8.2 kPa continues for 5
seconds
• If the pressure does not reach "+5.6 kPa" within 60 seconds after starting air feed
• If the state in which the pressure inside the channel cannot be maintained at +5.6 kPa
continues for 40 seconds or longer
• If the pressure does not reach "- 6.0 kPa" within 30 seconds after starting air discharge
In these cases, press the stop switch to stop the buzzer and then press the toggle switch to
discharge air. After that, take the following measures depending on the situation.
[Note] If control with the remote switch becomes inoperative, remove the tube from the
air inlet of the Endoscope and over-tube and carry out evacuation manually using a
syringe. Then, take out the Endoscope and over-tube while making sure of safety on
the monitor screen and stop the examination.
[Note] When the buzzer sounds, the toggle switch and the pause switch on the side (over-tube
side or endoscope side) that is in an error state do not operate until the buzzer is
cancelled.
Cause : External force has been applied to the balloon.
Countermeasure : Press the stop switch to clear the buzzer. The equipment automatically
reduces the pressure to +5.6 kPa to maintain the balloon status. Confirm
the safety on the Endoscope or X-ray image, and then restart operation.
Cause : A tube or connector is disconnected.
Countermeasure : Press the stop switch to clear the buzzer. The equipment automatically
maintains air feed condition. Locate the disconnected part of the tube kit
and reconnect the tube or connector.
Cause : The balloon is broken.
Countermeasure : Remove the endoscopic accessories during processing. Press the stop
switch to clear the buzzer. Press the toggle switch to discharge air from the
balloon, withdraw the endoscope and replace the balloon.
