A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 9Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the charger. 10Only use attachments/accessories specified by the manufacturer. 11Unplug this charger during lightning storms or when unused for long periods of time. 12Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. 13To reduce the risk of fire or electric shock, do not expose the charger to rain, moisture, dripping, or splashing. 4 RF-QX4/RF-QX4-T/RF-QX4-E/RF-QX4-J 14An apparatus with a three-prong, grounding-type plug is a Class I apparatus, which needs to be grounded to prevent possible electric shock. Make sure that you connect this Class I device to a grounding-type, three-prong outlet. 15In order to charge your headset correctly, the wall outlet must be in correct working condition. 16Batteries should not be exposed to excessive heat. Caution: Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type. Wa rning: If the volume is set too high, excessive sound pressure from earphones and headphones can cause hearing loss. Introduction Congratulations on your purchase of the RF-QX4 wireless headset.
