3• Disconnect the SIP-CS from the AC outlet, disconnect the LAN cable, and contactthe dealer if:– The AC adaptor cord or AC plug becomes damaged or frayed.– The SIP-CS is exposed to rain, water, or any other liquid.– The SIP-CS is dropped or damaged.– Internal components are exposed due to damage.– The SIP-CS does not operate properly.– Performance deteriorates.• Disconnect the SIP-CS from the AC outlet and disconnect the LAN cable if the SIP-CS emits smoke, an abnormal smell, or makes unusual noise. These conditionscan cause fire or electric shock. Confirm that smoke has stopped and contact anauthorised service centre.• Clean the AC plug periodically with a soft, dry cloth to remove dust and otherdebris.• If using an AC adaptor, use the optional AC adaptor KX-A239CE (PQLV206CE),KX-A239UK (PQLV206E), KX-A239BX (PQLV206CE), KX-A239EJ (PQLV206E),or KX-A239AL (PQLV206AL).• If damage to the SIP-CS exposes any internal parts, immediately disconnect thecable or cord. If the power is supplied from the network to the SIP-CS (Power-over-Ethernet), disconnect the Ethernet cables.Otherwise, disconnect the AC adaptor cord. Then return the SIP-CS to a servicecentre.• The SIP-CS should only be connected to a power supply of the type shown on thelabel on the SIP-CS.• Completely insert the AC adaptor/power plug into the AC outlet. Failure to do somay cause electric shock and/or excessive heat resulting in a fire.• Do not stretch or bend the cables. Also, do not allow anything to rest on the cables.• Do not bundle cables that are connected to the SIP-CS with the AC power cords ofmachines located nearby.• To prevent malfunction, deformity, overheating, rust, and discolouration, do notinstall or place equipment in the following types of locations:– Locations where air ventilation is poor.– Locations that may be exposed to sulphurous gas, such as near hot springs.– Near devices that emit heat, such as heaters.– Near devices that emit electromagnetic noise, such as radios or televisions.– Near devices that emit high-frequency noise, such as sewing machines orwelders.CAUTION
