Chapter 4 Inspection
ELECTROSURGICAL UNIT PSD-30
If the power fails to come on after replacing the fuses with
new ones, immediately turn the electrosurgical unit OFF.
Remove the power cord from the wall mains outlet and
contact Olympus. Equipment damage or malfunction may
have occurred and fire or electric shock can result.
4.2 Inspection of the foot switch
A malfunctioning foot switch could result in continuous
high-frequency output, which could cause injury to the patient
and/or operator. Also, high-frequency output may not
activated. In this case, the electrosurgical accessory could
cut the tissue mechanically, which could cause bleeding
and/or perforation to the patient.
To inspect the operation of the foot switch, press the cut pedal and coagulation
pedal individually after the electrosurgical unit is turned ON and confirm that an
alarm will sound and the output setting indicators (“FL” and “FS”) shown in
Figure 4.5 will light with both pedals. If pedal is released, alarm sound and
indicators are turned off. If not, the foot switch pedal may be defective. Replace
the foot switch.
