Brother MFC-J491DW Product Safety Guide

(MFC models only)
Use caution when installing or modifying telephone lines. Never touch telephone wires or
terminals that are not insulated unless the telephone line has been unplugged from the wall
socket.
Never install telephone wiring during a thunderstorm. Never install a telephone wall socket in
a location that is wet or may become wet, for example, near a refrigerator or other appliance
that produces condensation.
Power Cord Safety:
• (Not available for Taiwan) This product is equipped with an earthed plug. This plug will only
fit into an earthed electrical socket. This is a safety feature. If you are unable to insert the
plug into the socket, ask your electrician to replace your obsolete socket. DO NOT attempt
to defeat the purpose of the earthed plug.
• DO NOT allow anything to rest on the power cord.
• DO NOT place this product where people might step on the cord.
• DO NOT place this product in a position where the cord is stretched or strained, as it may
become worn or frayed.
• DO NOT use the product or handle the cord if the cord has become worn or frayed. If
unplugging your product, DO NOT touch the damaged/frayed part.
• DO NOT pull on the middle of the AC power cord; pulling on the middle may cause the cord
to separate from the plug. Doing this might cause an electrical shock.
• DO NOT use any undesignated cables (or optional devices). Doing so may cause a fire or
injuries. Installation must be performed properly according to the user's guide.
• Brother strongly recommends that you DO NOT use any type of extension cord.
• This product should be positioned so that nothing pinches or constricts the power cord.
• DO NOT use any cable that does not meet the applicable cable specifications described in
the Quick Setup Guide. Doing so may cause a fire or injuries. If the power cord is provided
with this product, use ONLY the provided cord. Installation must be performed correctly as
described in the Quick Setup Guide.
