NEVER connect the receiver via the OPC-254L to an AC outlet. This may pose a fire hazard or result in an electric shock. NEVER place the receiver where normal operation of the vehicle may be hindered or where it could cause bodily injury. RWARNING! NEVER operate the receiver while driving a vehicle. Safe driving requires your full attention-- anything less may result in an accident. NEVER let objects impede the operation of the cooling fan on the rear panel. AVOID using or placing the receiver in direct sunlight or in areas with temperatures below ­10°C (+14°F) or above +60°C (+140°F). NEVER connect the receiver to a power source of more than 14 V DC. This will damage the receiver. NEVER connect the receiver to a power source using reverse polarity. This will damage the receiver. BE CAREFUL! The receiver will become hot when operating it continuously for long periods. AVOID setting the receiver in a place without adequate ventilation. Heat dissipation may be affected, and the receiver may be damaged. AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they can damage the receiver's surfaces. For U.S.A. only CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations. NEVER cut the DC power cable between the DC plug and fuse holder. If an incorrect connection is made after cutting, the receiver may be damaged. DO NOT leave the main unit powered ON and connected to a vehicle's electrical system. The main unit draws approx. 550 mA. This will eventually drain the vehicle's battery. NEVER expose the receiver to rain, snow or any liquids. The receiver may be damaged. NEVER operate or touch the receiver with wet hands. This may result in an electric shock or damage the receiver. iii ABOUT APCO PROJECT 25 This device made under license under one or more of the following US patents: #4,590,473, #4,636,791, #5,148,482, #5,185,796, #5,271,017, #5,377,229.
