Under no circumstances should a user view the devices optical connectors using magnification unless the device is detached from the SCT series tester. Always cover the devices fiber optic output con

9、nector with the dust cap when not in use. The output source is active when the device is powered. Under no circumstances should a user look directly into the devices visual fault locators output. Long term exposure to the visual fault locators output is potentially hazardous. Under no circumstances

10、should a user activate the visual fault locator without first connecting the visual fault locator to the link under test. If this product is used in a manner not specified by the manufacturer hazardous radiation exposure might result. To prevent damage to the device and ensure result accuracy: It is

11、 important that fiber optic patch cords, fiber under test and adapters are clean prior to testing. Always clean and inspect fiber connectors prior to testing. Contamination can degrade optical performance, cause misalignment or cause back reflections leading to poor results. Contamination can also d

Do not use the device or accessories that appear damaged. Inspect the device and accessories before use. Safety warning for battery pa

13、ck: To avoid the risk of fire, burns, or damage to your battery pack, do not allow metal objects to touch the battery contacts. Only the battery supplied by the manufacturer (PN 6280-354) shall be used with the SCT. Do not disassemble the battery pack. There are no user serviceable parts inside. Do

14、not dispose of the battery pack in fire or water. Handle a damaged or leaking battery with extreme care. If you come in contact with the electrolyte, wash the exposed area with soap and water. If the electrolyte contacts the eye, flush the eye with water for 15 minutes and seek medical attention. Do

15、 not expose the battery pack to high storage temperatures (above +55C). When discarding a battery pack, contact your local waste disposal provider regarding local restrictions on the disposal or recycling of NiMH batteries. To obtain a replacement battery (PN 6280-354), contact your local authorized

16、 Megger dealer. Do not charge the battery pack if the ambient temperature is above +40C.
