Turn off the power switch.

y

If the equipment is provided with more than two probe connectors, using the probe selection key select the other probe connector than the one to which the probe is connected or disconnected and set FREEZE ON.

4. The probes to which pressurized or depressurized gas sterilization can be applied are described in the Instruction Manual of each probe. Sterilize probe according to the method described in the Instruction Manual. 5. In case of the probes to which pressurized or depressurized gas sterilization cannot be applied, never put them in the following atmosphere. If this is not observed, the probe may be damaged. y

At temperature higher than 40°C

y

In the pressurized gas

y

In the depressurized gas

y

Disinfection or sterilization other than the specified

7.6 Precautions against ultrasound output power When the equipment is used for the patient with high susceptibility such as fetus, pay attention to the following: y

Set the ultrasound output power to the level as low as possible and adjust sensitivity with the gain control.

y

To prevent unnecessary ultrasound output power, try to set FREEZE to ON whenever depiction of ultrasound image is not necessary.

y

Because effect by ultrasound power on the imaging area in the M, PW, CW and CFM-modes is greater than in the B-mode, try to use it at the level as minimum as possible.
