B Do not continue to use the projector in such cases, otherwise fire or electric shocks could result. B Check that no more smoke is coming out, and then contact an Authorised Service Center for repairs. B Do not attempt to repair the projector yourself, as this can be dangerous. Do not install this projector in a place which is not strong enough to take the full weight of the projector. B If the installation location is not strong enough, it may fall down or tip over, and severe injury or damage could result. Installation work (such as ceiling suspension) should only be carried out by a qualified technician. B If installation is not carried out correctly, there is the danger that injury or electric shocks may occur. If foreign objects or water get inside the projector, or if the projector is dropped or the cabinet is broken, turn off the power and disconnect the power cord from the wall outlet. B Continued use of the projector in this condition may result in fire or electric shocks. B Contact an Authorised Service Center for repairs. Do not overload the wall outlet. B If the power supply is overloaded (for example, by using too many adapters), overheating may occur and fire may result. Do not remove the cover or modify it in any way. B High voltages which can cause fire or electric shocks are present inside the projector. B For any inspection, adjustment and repair work, please contact an Authorised Service Center. Clean the power cord plug regularly to prevent it from becoming covered in dust. B If dust builds up on the power cord plug, the resulting humidity can damage the insulation, which could result in fire. Pull the power cord out from the wall outlet and wipe it with a dry cloth. B If not using the projector for an extended period of time, pull the power cord plug out from the wall outlet.
