    CAUTION 1. Intended product use • The Retinomax 3 is only intended to be used for measuring refractive power and pupil diameter. Do not use it for any other purpose.
  • Page 6 • The operating environment: Temperature 10°C to 40°C, relative humidity 30% to 90% (no condensation), atmospheric pressure 700-1060 hPa • Although the instrument is designed with dust protection, it should not be used in a dusty room. • The best location for the instrument is a room equivalent to a semi-dark room.
  • Page 7 • Never short-circuit the battery charging contacts of the main unit, station, or printer. If the contacts are short-circuited, the fuse of the station or printer will blow. • Do not expose the connectors or battery charging contacts to your body or metal objects. If a contact is dirty, turn the power off and wipe the contact off with a dry, soft cloth.
  • Page 8 • When cleaning the glass in the measuring window, be careful not to scratch or break the lens. • After use, turn off the power switch of the station and put on the dust cover. • If you plan to put the instrument out of service for a long time, pull the power cord out from the receptacle outlet.
  • Page 9 • If you leave the printer connected to the station, you are advised to remove the battery pack from the printer to prevent the battery from degrading. • The battery pack is effective for three years. You are advised to write down the date when you started to use the battery on the supplied battery date sticker and affix it to the battery pack case.
