IC-2720H_2.qxd 03.5.13 9:45 Page i (1,1) RWARNING RF EXPOSURE!This device emits Radio Frequency (RF) energy. Extreme caution should be observed when operating this device. If you have any questions regarding RF expo- sure and safety standards please refer to the Federal Communica- tions Commission Offi ce of Engineering and Technologys report on Evaluating Compliance with FCC Guidelines for Human Radio fre- quency Electromagnetic Fields (OET Bulletin 65). RWARNING! NEVERconnect the transceiver to an AC out- let. This may pose a fi re hazard or result in an electric shock. RWARNING! NEVERoperate the transceiver while driving a vehicle. Safe driving requires your full attentionanything less may result in an accident. NEVERconnect the transceiver to a power source of more than 16 V DC. This will damage the transceiver. NEVERconnect the transceiver to a power source using reverse polarity. This will damage the transceiver. NEVERcut the DC power cable between the DC plug and fuse holder. If an incorrect connection is made after cutting, the transceiver may be damaged. NEVERexpose the transceiver to rain, snow or any liquids. The transceiver may be damaged. NEVERoperate or touch the transceiver with wet hands. This may result in an electric shock or damage the transceiver. NEVERplace the transceiver where normal operation of the vehi- cle may be hindered or where it could cause bodily injury. NEVERlet objects impede the operation of the cooling fan on the rear panel. DO NOTpush the PTT when not actually desiring to transmit. DO NOTallow children to play with any radio equipment contain- ing a transmitter. During mobile operation, DO NOToperate the transceiver with- out running the vehicles engine. When the transceivers power is ON and your vehicles engine is OFF, the vehicles battery will soon be- come exhausted. AVOIDusing or placing the transceiver in direct sunlight or in areas with temperatures below 10C or above +60C. BE CAREFUL!The transceiver will become hot when operat- ing it continuously for long periods. AVOIDsetting the transceiver in a place without adequate venti- lation. Heat dissipation may be affected, and the transceiver may be damaged. AVOIDthe use of chemical agents such as benzine or alcohol when cleaning, as they can damage the transceivers surfaces. USEIcom microphones only (supplied or optional). Other manu- facturers microphones have different pin assignments and may dam- age the transceiver if attached. For U.S.A. only CAUTION: Changes or modifi cations to this device, not ex- pressly approved by Icom Inc., could void your authority to operate this device under FCC regulations. ii New2001 PRECAUTION IC-2720H_2.qxd 03.5.13 9:45 Page ii (1,1) New2001 iii TABLE OF CONTENTSSUPPLIED ACCESSORIES q DC power cable (3 m) 1 w Mobile mounting bracket1 e Microphone (HM-133)*1 r Fuse (20 A) 1 t Mounting screws, nuts and washers 1 set y Microphone hanger 1 u Remote controller bracket (MB-84) 1 i Mounting screws, nuts and washers for MB-84 1 set o Separation cable(3.5 m; 11.5 ft) 1 *HM-118N HAND MICROPHONEor HM-118TN/TAN DTMF MICROPHONE supplied versions are also available.
