Page 4: Precautions For Use
4. Note the following points during use: (1) Use minimum illumination intensity required throughout the examination process: this will not only reduce the discomfort of the examinee due to the glare but also extend the life of the lamps. (2) Constantly monitor that the instrument is operating normally and that the examinee is not in discomfort. (3) Where any abnormality is found in the instrument or the examinee, take necessary actions such as making sure that the examinee is safe and turning the instrument off. (4) During use, never loosen the balance adjustment handle or the vertical movement lock handle. 5. Note the following points after use: (1) Following use, be sure to turn off the power switch. (2) When unplugging the power cord or other cables, be sure to do so by holding the plug and pulling it out so that the power cord or cables are not strained. (3) Following use, be sure to protect the OM-8 by covering it with the dust cover. (4) When moving the OM-8, lock all of the lock handles and be careful not to bump it into anything. 6. Note the following points upon storage: (1) Do not store the instrument in a place where water may be splashed on it. (2) Do not store the instrument in a place that may affect the condition of it due to abnormal atmospheric pressure, temperature or humidity as well as poor ventilation, exposure to direct sunlight, dust or air containing salt or sulfur. (3) Be sure that the instrument is stored on a stable surface; Do not store it on a sloping surface or in a place subject to vibration or impact. (Also, avoid impact in transport.) (4) Do not store the instrument in a place where chemicals are stored or where it may be exposed to gas. (5) Clean the instrument prior to storing so that it stays in good condition till it is required next time. 7. Note the following points upon maintenance: (1) Open the lamp housings only when replacing lamps. There are no other user-serviceable parts inside the instrument. (2) When replacing lamps, turn the OM-8 power off, and wait till the lamps are cool enough to handle.
