Operation

The operator of this instrument must be a physician or medical personnel under the supervision of a 
physician and must have received sufficient training in clinical procedures of microsurgery using 
surgical microscope. This manual, therefore, does not explain or discuss the details of microsurgery 
using surgical microscope. This chapter therefore pertains only to the basic operating procedures and 
basic warnings and cautions to be used in the operation.

WARNING

• Always wear appropriate protection gear. Otherwise, contact with hazardous 

substances such as chemicals and infective matters such as blood and mucus of 
the patient may cause health damage to the operator and/or assistant.

• If any irregularity is suspected during use, immediately stop using the equipment 

and take proper measures by referring to Chapter 8, “Troubleshooting” as well as 
the instruction manuals of the ancillary equipment used in combination with this 
instrument. If this instrument continues to be used while an irregularity is 
suspected, damage to the patient’s health may result.

CAUTION

• The illumination lamp lights automatically when the LED light source and surgical 

microscope are turned ON. Do not look directly at the illumination lens of the 
surgical microscope while the illumination light is output from it. Also, do not point 
the illumination lens to others. Otherwise, an eye injury may result.

• When the illumination is not required, press the lamp button of the surgical 

microscope to extinguish the lamp. If the illumination lamp is left lighted, the 
illumination light irradiation on a position other than the observed region may cause 
burns to the operator or patient.

• Combination with other equipment

Do not install this instrument in the proximity of a source of strong 
electromagnetic waves (microwave therapy equipment, shortwave therapy 
equipment, MRI, radio, cellphone, etc.). Otherwise, this instrument may fail.

When using high-frequency electrosurgical equipment combination with this 
instrument, confirm that the high-frequency noise is at a level that does not 
affect the operation of this instrument in advance. Otherwise, malfunction may 
result.
