    Caution 1. Purpose of using the equipment ・ Use ACOMOREF 2 only for the purposes of examining the refractive power, such as measurement of the eye refractive power (Spherical, Cylinder, Axis), pupil size etc. Do not use the equipment for others purposes.
  • Page 7 ・ While operating the equipment, be careful to prevent your fingers from being caught by the machine. ・ When moving the chin rest up and down, the examiner must notify the patient movement and keep an eye on the patient during the operation. Operating the equipment without keeping an eye on the patient may injure the patient.
  • Page 8 ・ The ambient conditions of use: Temperature 10°C to 35°C, Relative humidity 30% to 90% (no dew condensation), Atmospheric pressure 800–1060 hPa ・ Avoid using the equipment in a dusty or dirty room. ・ A semi-dark room is best suited for installation of the equipment. Do not place the equipment facing a bright window or an illumination light.
  • Page 9 ・ This equipment is not waterproof. Therefore, avoid using or installing the equipment in a place where liquids, such as rainwater, drinks, chemicals, etc. may splash on it. ・ When condensation (wet from dew) occurs, wait until the dew dries before using the equipment.
  • Page 10 ・ This is a precise optical device equipment embedded with many electrical components. Handle the equipment with care, avoiding impacts. ・ Pay attention to avoid dropping the equipment or hitting it against another object. ・ In case of a failure, unplug the power cord, and contact your dealer without touching the inside of the equipment, etc.
  • Page 11 (especially, forehead support and chinrest) with a cloth dampened with rubbing alcohol for disinfection. ・ Accessory equipment connected to the analog and digital interfaces must be certified according to the appropriate national standards. Furthermore, all configurations shall comply with the IEC 60601-1. Anyone who connects additional equipment to the signal input part or signal output part is responsible for making sure that the system complies with the requirements of the IEC 60601-1.
  • Page 12 While cleaning the measurement window glass, be careful not to damage or break the glass. ・ Built-in battery This equipment has a built-in lithium primary battery as a power supply for the clock and storing various setting. If the battery is exhausted, the time and date printed on the printout results of measurement will be wrong, or various settings will not be stored and thus the equipment is set back to the default settings each time when it turned off.
