Pre-Use Inspection - Pentax LH-150PC Owner's Manual

3-2. PRE-USE INSPECTION

WARNING:
Before every use, the following points should be checked:
If any function or device in the endoscopic system does not perform properly, do NOT perform the
endoscopic examination.
Contact the manufacturer of the device, your PENTAX sales representative or a PENTAX service
center before using the equipment for an endoscopic examination.
1) Ensure that the power cord is firmly plugged into a properly grounded receptacle.
CAUTION:
Do NOT stretch the cord tight to prevent the plug from coming off.
2) Ensure that an endoscope is connected to the appropriate light guide socket properly.
3) Turn the power switch ON by depressing the power switch labeled ( I ).
4) Confirm that light is seen at the distal end of scope.

WARNING:
Avoid looking directly at the light exiting the endoscope or the light source.
NOTE:
If the power is not turned ON, replace the fuse on
the rear panel.
If the lamp fails to light, replace the lamp.
CAUTION:
As a precaution, always have an extra (spare) lamp
available as a standby lamp.
5) Depress the air pump switch.
•
6) Exercise Air/Water delivery through the endoscope. Covering
air venting hole on top of Air/Water button lightly should
deliver air at the distal end of the endoscope. By submerging
the distal end in enough water to cover the tip, air flow will be
demonstrated by a trail of bubbles. Pressing the button all the
way down should deliver water through the tip of the
endoscope. Use sterile water only.
If all items above appear to function satisfactorily, then the
endoscopic procedure may be performed. If any functionality
above is compromised, do NOT attempt to perform the
endoscopic procedure.
7) Turn the brightness control knob clockwise to increase the
brightness level or counterclockwise to decrease the
brightness level.
