Installation Precautions
 The receiver uses a very weak infrared light for its signal, which can result in the signal not being
received because of the following inuences, so take care in where the indoor unit is installed.
• Inverter or rapid-start type uorescent lights (Models without glow lamps)
• Plasma display or LCD televisions
• Direct sunlight or other sources of bright light
 Do not bundle together with the power source wiring or store in the same metal tube. Operation
error may occur.
 Be careful not to connect cables to other terminals of indoor units (e.g. power source wiring
terminal). Malfunction may occur.
 Avoid the following locations for installation.
• Location where condensation occurs
• Location where voltage uctuation frequently occurs
• Location where there is a machine producing electromagnetic radiation
