1、HF/50 MHz ALL MODE TRANSCEIVER i703 INSTRUCTION MANUAL i FOREWORD Thank We understand that you have a choice of many different radios in the market place. We want to take a couple of moments of your time to thank you for mak- ing the IC-703 your radio of choice, and hope you agree with Icoms philoso

2、phy of “technology first.” Many hours of research and development went into the design of your IC-703. FEATURES DSP features (AF DSP; UT-106 DSP UNITrequired some version) All mode capability covering 1606 m 9.015.87 V operation Compact with detachable front panel 0.5 ppm of high frequency stability

3、 Built in antenna tuner Simple band scope function IMPORTANT READ THIS INSTRUCTION MANUAL CAREFULLYbefore attempting to operate the transceiver. SAVE THIS INSTRUCTION MANUAL.This manual contains important safety and operating in- structions for the IC-703. EXPLICIT DEFINITIONS RWARNING RF EXPOSURE!T

4、his 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 Technologys report on Evalu- ating Compli

5、ance 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 the DC13.8V receptacle on the transceiver

6、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 other objects touch any in- ternal part or co

7、nnectors 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 aware that temperatures on a vehicles dashb

8、oard 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 anything on top of the transceiver. This w

9、ill 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, the vehicles battery will soon become ex

10、hausted. 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 the magnetic navigation compass to prevent

11、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 maximum input level, otherwise, the linear amp

12、li- 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 occur as a result of circuit construction.

13、 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、round 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 other peripheral equipment. This include

39、s 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- tion is the electrical contact between

40、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 EMI. Although you may not see interferen

41、ce 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 interference from your shack. If you do no

42、t 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 system, the shortest most direct connection i

43、s 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 lines to plastic (pvc) pipe. DD Some Sympto

44、ms 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 While transmitting and you feel a tinglin

45、g 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 is a device used to convert 110/220 V AC,

46、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 DC power cable (OPC-1229) to the appropri

47、ate 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 electrical devices in the shack, it is very imp
