4、PLICIT DEFINITIONS 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 exposure and safety standards please refer to the Federal Communications Commission Offi ce of Engineering and

5、Technologys report on Evalu- ating Compliance with FCC Guidelines for Human Radio Frequency Electromagnetic Fields (OET Bulletin 65). RWARNING HIGH VOLTAGE! NEVERattach an antenna or internal antenna connector during transmis- sion. This may result in an electrical shock or burn. RNEVERapply AC to t

6、he DC13.8V receptacle on the transceiver rear panel. This could cause a fi re or damage the transceiver. RNEVERapply more than 16 V DC, such as a 24 V battery, to the DC13.8V receptacle on the transceiver rear panel. This could cause a fi re or damage the trans- ceiver. RNEVERlet metal, wire or othe

7、r objects touch any in- ternal part or connectors on the rear panel of the trans- ceiver. This may result in an electric shock. NEVER expose the transceiver to rain, snow or any liquids. AVOID using or placing the transceiver in areas with tem- peratures below 10C (+14F) or above +60C (+140F). Be aw

8、are that temperatures on a vehicles dashboard can exceed 80C (+176F), resulting in permanent damage to the transceiver if left there for extended periods. AVOID placing the transceiver in excessively dusty envi- ronments or in direct sunlight. AVOID placing the transceiver against walls or putting a

9、nything on top of the transceiver. This will obstruct heat dissipation. Place unit in a secure place to avoid inadvertent use by children. During mobile operation, DO NOT operate the transceiver without running the vehicles engine. When the trans- ceivers power is ON and your vehicles engine is OFF,

10、 the vehicles battery will soon become exhausted. Make sure the transceiver power is OFF before starting the vehicle. This will avoid possible damage to the trans- ceiver by ignition voltage spikes. During maritime mobile operation, keep the transceiver and microphone as far away as possible from th

11、e magnetic navigation compass to prevent erroneous indications. BE CAREFUL! The rear panel will become hot when op- erating the transceiver continuously for long periods. BE CAREFUL! If a linear amplifi er is connected, set the transceivers RF output power to less than the linear am- plifi ers maxim

12、um input level, otherwise, the linear ampli- fi er will be damaged. Use Icom microphones only (supplied or optional). Other manufacturers microphones have different pin assign- ments, and connection to the IC-703 may damage the transceiver. Beat signals may be heard on some frequencies. These will o

13、ccur as a result of circuit construction. For U.S.A. only Caution: Changes or modifi cations to this transceiver, not expressly approved by Icom Inc., could void your authority to operate this transceiver under FCC regulations.

38、RENCE GUIDE I Installation 1. Install a ground system for DC noise suppression and RFI suppression 2. Install your DC power supply 3. Install lightning protection. This will help protect more than your gear. 4. Install and connect an antenna system for the ap- propriate bands of operation 5. Connect

39、 other peripheral equipment. This includes microphones, headsets, TNC, amplifiers and any other equipment necessary to make your shack complete. Although your radio will operate by connecting the DC power supply and antenna, it is necessary to have a good ground system in your shack. A ground connec

40、- tion is the electrical contact between the common point of an electrical or electronic system and the earth. A good earth ground is necessary to prevent electrical shock, eliminate problems from RFI and DC noise. With more electronic devices being used today, it is also important to reduce RFI and

41、 EMI. Although you may not see interference in your shack, without a grounding system, your neighbours may experience interference. Even though many of these devices are Part 15, where they must accept interference from their surrounding environment, it is best to eliminate as much of the possible i

42、nterference from your shack. If you do not have a grounding system for your shack, depending on the location of your shack, basement or ground fl oor, a good ground system can be as simple as a couple of ground rods driven 6 to 8 feet into the soil. When installing your IC-703 to your grounding syst

43、em, the shortest most direct connection is recom- mended. NOTE: There are many publications covering proper grounding techniques. Check with your local dealer for more information and recommendations. RWARNING!: NEVERground station equip- ment or antennas to house gas lines. NEVER at- tach ground li

44、nes to plastic (pvc) pipe. DD Some Symptoms if inadequate grounding a. Poor DC Ground 50/60 Hz hum on the audio either Rx or Tx without the antenna connected. If you feel a tingling sensation when you touch a metal surface. Surfaces such as the cover of your radio or power supply. b. Poor RF Ground

45、While transmitting and you feel a tingling sensation when you touch a metal surface. Surfaces such as the cover of your radio or power supply. While transmitting, you experience interference to other electronic devices, such as the telephone, television or stereo audio systems. The DC power supply i

46、s a device used to convert 110/220 V AC, also know as Household current, to a steady source of 13.8 V DC. The perfect match to your IC-703 is the PS-125. This plug and play unit plugs into the DC power recepta- cle using an optional OPC-1248 located on the rear of the radio. Or connect the supplied

47、DC power cable (OPC-1229) to the appropriate color coded terminals, then insert the DC connector into the DC power receptacle lo- cated on the rear of the radio. NOTE: Although the power supply current require- ment is quite low during receiving, this not the case when you transmit. With many electr

48、ical devices in the shack, it is very important to verify the electrical circuit is not overloaded. 1. Grounding your Shack 2.
