RNEVERexpose the repeater to rain, snow or any liquids. AVOID using or placing the repeater in areas with tem- peratures below 25C or above +5

5、5C. AVOID placing the repeater in excessively dusty envi- ronments or in direct sunlight. AVOID putting anything on top of the repeater. This will obstruct heat dissipation. Place the repeater in a secure place to avoid inadver- tent use by children. BE CAREFUL! The heatsink will become hot when op-

If a linear amplifier is connected, set the repeaters RF output power to less than the linear amplifi ers maximum input level, otherwise, the linear amplifi er will be damaged. Use Icom microphones only (optional). Other manu- facturer

7、s microphones have different pin assignments, and connection to the IC-FR3100/FR4100 series may damage the repeater.

21、iated antenna should be made in such a manner as to re- spect the EC recommended electromagnetic (EM) fi eld exposure limits. (1999/519/EC) In order not to exceed these exposure limits it is nec- essary to determine the Compliance Boundary, that means the volume within which the EM fi eld radiated b

22、y the transmitter/antenna installation may exceed the 1999/519/EC limits. You will then need to ensure that members of the general public do not have access within this area. The actual Compliance Boundary for this repeater will be totally dependant on the antenna, feeder, RF amplifier and other pas

23、sive or active de- vices used in the installation. The RF output power of this repeater is 25 watts. The fi gures contained in this guide are based on the recommended limits for the general public and are ob- tained by worst case numerical analysis. For a defi ni- tive evaluation of any given instal

24、lation, measurements should be made with an EM fi eld meter and a broad- band calibrated probe. Installation The antenna should be installed as high as possible for maximum efficiency and minimum EM field at ground-level. The evaluation of radiated field should take into account any additional RF am

25、plifiers used, any loss in the antenna feeder cable and the gain of the antenna used as well as its polar radiation pattern. If there are any objects or structures larger than half a wavelength close to the antenna, or within the clear- ance distances specifi ed, then these can cause refl ec- tions

26、which will have an effect on the overall radiation pattern. For any installation you need to consider height clear- ance (i.e. the height above any place where persons may have access) and front clearance (i.e. the dis- tance in front of the antenna where the radiated fi eld may exceed the recommend

27、ed limits). Normally with an antenna installed on a reasonably high mast or tower, there will not be any access point directly in front but care should be exercised when there are other buildings higher than the antenna within the vicinity. Installation with a vertical type antenna at VHF-UHF You ne

28、ed to consider the distances between the an- tenna and any point where persons may have access. Allowing an average height of 1.8 m for a person in the vicinity of the antenna the clearance distances can be evaluated as follows. For the antenna a forward gain of 1.6 and downward gain of unity has be

29、en assumed.

30、dominant ra- diation pattern is forwards and that radiation vertically downwards is at unity gain (sidelobe suppression is equal to main lobe gain). This is true of almost every gain antenna today. Exposed persons are assumed to be beneath the antenna array and have a typical height of 1.8 m. The fi

31、 gures assume the worst case emission of con- stant carrier.

The transmit power is 25 watts, there is 20 m of RG- 213 coa

33、xial cable and the antenna is vertically po- larised dipole. The specifi cation of the RG-213 cable gives a loss of 1.5 dB/10 m. There will be 3 dB loss for the 20 m length used. The RF power at the antenna input will be 12.5 watts. The dipole antenna has a forward gain of 0 dBd or 1.6, giving an EI

34、RP of 20 watts. Referring to the table above for VHF/UHF vertical an- tennas, this gives a front clearance distance of approx. 1.5 m and a height clearance of 3 m. The antenna installation needs to ensure that the low- est part of the antenna is at least 3 m above any point where the general public

35、may gain access and that they cannot pass within 1.5 m in front of the antenna. If there is no general public access to the roof in ques- tion then the antenna could be mounted on a short stub mast. If there is such access to the roof then the antenna could be mounted on top of a short mast of 3.2 m

36、 high. The mast position should be such that the antenna can radiate clearly i.e. no other object or structure is within 1.5 m (preferably more). It should be relatively easy to fulfil all these recom- mendations. If for any reason such minimum distances are impos- sible to guarantee then some type

37、of access control fence or barrier around the antenna installation should be provided. Should a Yagi type antenna be used then you will have to obtain a 3 dimensional polar plot of the radiation characteristic from the manufacturer and evaluate the clearance distances in both vertical and horizontal

38、 planes. Operating Notes All of the above comments on RF safety assume that the radio is transmitting continuously in a constant car- rier mode such as FM or RTTY etc. The RF exposure limits recommended by the EC are based on the mean power averaged over a 6 minute period. Therefore if the total tra

39、nsmit time during any 6 minute period is reduced, then the installation will be even fur- ther within the recommended limits. Similarly, not all operating modes are constant carrier. AM type modes all have a lower mean power level. Use of SSB or CW will reduce exposure by approxi- mately 70% for thi

40、s reason. CE Versions of the IC-FR3100/FR4100 which display the “CE” symbol on the serial number seal, comply with the essential re- quirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC. This warning symbol indicates that this equipment operates in non-harmonised frequ

41、ency bands and/or may be subject to licensing conditions in the country of use. Be sure to check that you have the correct version of this radio or the correct pro- gramming of this radio, to comply with na- tional licensing requirement. 19 8ABOUT CE Network Compatibility Notice Icom IC-FR3100/IC-FR
