FOREWORD Thank you for purchasing this Icom product. The IC-2100H/-T 144 MHz FM TRANSCEIVER is designed and built with Icom's superior technology and craftsmanship. With proper care this product should provide you with years of trouble-free operation. CAUTIONS RWARNING! NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock. RWARNING! NEVER operate the transceiver while driving a vehicle. Safe driving requires your full attention-- anything less may result in an accident. NEVER connect the transceiver to a power source of more than 16 V DC. This will ruin the transceiver. IMPORTANT READ ALL INSTRUCTIONS pletely before using the transceiver. carefully and com- SAVE THIS INSTRUCTION MANUAL--This instruction manual contains important operating instructions for the IC-2100H/-T. NEVER connect the transceiver to a power source using reverse polarity. This will ruin the transceiver. NEVER cut the DC power cable between the DC plug and fuse holder. If an incorrect connection is made after cutting, the transceiver may be damaged. NEVER place the transceiver where normal operation of the vehicle may be hindered or where it could cause bodily injury. EXPLICIT DEFINITIONS DEFINITION Personal injury, fire hazard or electric RWARNING shock may occur. CAUTION NOTE ii Equipment damage may occur. If disregarded, inconvenience only. No risk of personal injury, fire or electric shock. WORD NEVER let objects impede the operation of the cooling fan on the rear panel. DO NOT push the PTT when not actually desiring to transmit. DO NOT allow children to play with any radio equipment containing a transmitter. SUPPLIED ACCESSORIES During mobile operation, DO NOT operate the transceiver without running the vehicle's engine. When transceiver power is ON and your vehicle's engine is OFF, the vehicle's battery will soon become exhausted. 1 4 7 2 5 8 0 3 6 9 # A B C D M BE CAREFUL! The transceiver will become hot when operating it continuously for long periods. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below ­10°C (+14°F) or above +60°C (+140°F). AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they can damage the transceiver's surfaces. USE Icom microphones only (supplied or optional). Other manufacturer's microphones have different pin assignments and may damage the transceiver if attached. For U.S.A. only Caution: Changes or modifications to this transceiver, not expressly approved by Icom Inc., could void your authority to operate this transceiver under FCC regulations.
