Open the wind protector by the hand, loosen the electrode fixture screws by finger and remove both electrodes from the splicer. Fibre fusion splicers are critical instruments in modern optical fibre installation and maintenance. When properly maintained and operated, they produce low-loss, high-strength splices. Disconnect the AC power cord from the AC adapter inlet or the wall socket (outlet) immediately if user observes the following or if the splicer receives the following faults: • Fumes, bad smell, noise, or over-heat occurs. Over time, the 90R's electrodes will become worn as they complete fusion. Ensure proper fibre cleaving techniques, using a high-quality fibre cleaver and following manufacturer guidelines. To counteract these errors, technicians can go through the following troubleshooting checklists: Perform an Arc Test: Before splicing, it's important to perform.
