SAFETY PRECAUTIONS: Usage Precautions
CAUTION
• Never press on the LCD with a hard object such as a ball-point pen.
• There may be a few defective or constantly-lit pixels on the LCD.
This does not represent failure of the LCD; it is due to the structure of the LCD.
• Patient environment
The patient environment is the volume of space in which contact can occur between the patient and
any part of the device or between the patient and any other person(s) touching the device.
Use devices that comply with IEC 60601-1 in the patient environment.
If any device that does not comply with IEC 60601-1 is to be used, use an isolation transformer or
common protective grounding.
If the device is connected to the EyeCa-RW2 whose power is supplied though an AC adapter for 200
V or a computer that does not comply with IEC 60601-1 (except one that uses an AC adapter that
meets the Class II requirements of IEC 60950-1), supply power to the device and computer through
isolation transformers.
