INSTRUCTION MANUAL COMMUNICATIONS RECEIVER iC- r8500 IMPORTANT READ THIS INSTRUCTION MANUAL CAREFULLY before attempting to operate the receiver. EXPLICIT DEFINITIONS DEFINITION Personal injury, fire hazard or electric RWARNING shock may occur. CAUTION NOTE Equipment damage may occur. If disregarded, inconvenience only. No risk of personal injury, fire or electric shock. WORD SAVE THIS INSTRUCTION MANUAL. This instruction manual contains important safety and operating instructions for the IC-R8500. Versions of the IC-R8500 which display the "CE" symbol on the serial number seal, comply with the essential requirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC, and that any applicable Essential Test Suite measurements have been performed. PRECAUTIONS RINDOOR USE ONLY! NEVER expose the IC-R8500 or AC adapter to rain, snow or any liquids. AVOID using or placing the receiver in areas with temperatures below ­10°C (+14°F) or above +50°C (+122°F). AVOID placing the receiver in excessively dusty environments or in direct sunlight. AVOID placing the receiver against walls or putting anything on top of the receiver. This will obstruct heat dissipation. RESPECT other people's privacy. Information overheard but not intended for you cannot lawfully be used in any way. RNEVER connect the receiver to an AC outlet directly. This may pose a fire hazard or result in an electric shock. Always use the supplied AC adapter or connect to a 13.8 V DC power source. RNEVER connect to an AC outlet that exceeds the suggested voltage for each AC adapter version. This could cause a fire or ruin the AC adapter and/or receiver. RNEVER use non-rated fuses. Non-rated fuses could cause a fire or ruin the receiver. NEVER let metal, wire or other objects touch any internal part or connectors on the rear panel of the receiver. This will cause electric shock.
