    The NOTE sign information that may be beneficial during the use and maintenance of the instrument. WARNING OLT-301 Series Optical Loss Tester is a laser device. User should always avoid direct eye exposure to the laser output. Using microscope or magnifier to observe the laser output should also be avoided: laser beam may converge on the retina and cause permanent eye injury.

    2. Basic Operation 2.1 Foreword This part introduces the basic operation on the OLT-301 Series testers. Specific operations are elaborated in Chapter 3 of this manual. Please read this manual carefully for optimal operation. If you encounter any problems during operation, you are welcome to contact the technical staff of our company or representatives.

  • Page 8: Indicator

    The OLT-301 Series works on lithium battery. Please make sure battery is mounted properly before use. When battery is low, low battery indicator will appear on LCD. You can still use the OLT-301 Series as long as its display on LCD is identifiable. When LCD display becomes dim, laser source output will become unstable and power meter measurement will be inaccurate.
