tach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn.

RWARNING HIGH VOLTAGE! NEVERinstall

the antenna in any place that a person can touch the antenna easily during transmission. This may result in an electrical shock or burn.

R NEVER apply AC to the [BATTERY] terminals on

the repeater rear panel. This could cause a fire or damage the repeater.

R NEVER apply more than 16 V DC, such as a 24 V

battery, to the [BATTERY] terminals on the repeater rear panel. This could cause a ﬁre or damage the repeater.

R NEVER let metal, wire or other objects touch any

internal part or connectors on the rear panel of the repeater. This may result in an electric shock.

R NEVER expose the repeater to rain, snow or any

liquids.

AVOID using or placing the repeater in areas with tem-

peratures below –25°C or above +55°C.

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 inadvertent use by children.

BE CAREFUL! The heatsink will become hot when op-

erating the repeater continuously for long periods.

BE CAREFUL! If a linear amplifier is connected, set

the repeater’s RF output power to less than the linear ampliﬁer’s maximum input level, otherwise, the linear ampliﬁer will be damaged.

INST ALLATION AND CONNECTIONS

■ Unpacking

After unpacking, immediately report any damage to the delivering carrier or dealer. Keep the shipping cartons.

For a description and a diagram of accessory equipment included with the IC-FR3100/FR4100 series, see ‘Supplied Accessories’ on p. ii of this manual.

■ Selecting a location

Select a location for the repeater that allows adequate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna elements, radios and other electromagnetic sources.

■ Antenna connection

For radio communications, the antenna is of critical importance, along with output power and sensitivity. Selecting antenna(s), such as a well-matched 50 Ω antenna, and feedline. 1.5:1 or better of Voltage Standing Wave Ratio (VSWR) is recommended for the desired band. Of course, the transmission line should be a coaxial cable.

CAUTION: Protect the repeater from lightning by

using a lightning arrestor.

NOTE: There are many publications covering

proper antennas and their installation. Check with your local dealer for more information and recommendations.

■ Duplexer

A duplexer is separately required when only one antenna is used for both transmitting and receiving. Select a duplexer according to the transmitting and receiving frequencies. Ask your Dealer for details.

■ Grounding

To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, ground the transceiver through the [GND] terminal on the rear panel.

For best results, connect a heavy gauge wire or strap to a long earth-sunk copper rod. Make the distance between the [GND] terminal and ground as short as possible.

WARNING:

NEVER connect the [GND] termi-

nal to a gas or electric pipe, since the connection could cause an explosion or electric shock.

INSTALLATION AND CONNECTIONS

■ Power

Make sure the [POWER] switch is turned OFF when connecting an AC power cable and a backup battery (emergency power supply).

The IC-FR3100/FR4100 series can operate with an AC or DC power supply. If AC power is interrupted when operating the repeater with an AC power supply, power is automatically provided to the [BATTERY] terminals.

NOTE: When repeatedly to turning the repeater ON

and OFF quickly, the repeater may not turn ON. In this case turn OFF the power switch and wait for a while, then turning power ON again.

D In AC operation

• The [DC] indicator turns OFF.

• Use the supplied AC power cable for connection to a

domestic AC outlet.

• Extension cords should not be used unless ab-

solutely necessary. Using improper extension cords could result in ﬁre risk.

• Usually the battery is continuously charged with a

small amount of current from an AC power supply through the regulator circuit in the repeater. Discharging is therefore prevented even if the battery is not used for a long time.

D In DC operation

CAUTION: Voltages greater than 16 V DC will dam-

age the repeater. Check the source voltage before connecting the power cable.

• The [DC] indicator lights up green.

• DO NOT place the backup battery on or near the re-

peater. Lead-acid batteries should be placed at least 5 m away from the repeater. Use a heavy duty cable to make the connection and be sure both the positive (red) and negative (black) terminals are correctly connected.

• Connect cables to the battery in the following order.

Connect the DC power cable to the repeater first, then the positive (red) terminal and negative (black) terminal to the battery to prevent an electric shock.

• After the battery is connected and the [POWER]

switch is ON, the repeater continuously supplies approx. 1 A for charging the battery. If the repeater stops functioning while connected to the battery, disconnect the battery, recharge it, then connect the battery to continue operation after the battery is charged. During repeater transmission, approx. 15 A of battery power is consumed.

■ Mounting the repeater

INSTALLATION NOTES

• Compliance of base station transmitter installations with EN50385

The installation of this equipment and it’s associated antenna should be made in such a manner as to respect the EC recommended electromagnetic (EM) ﬁeld exposure limits. (1999/519/EC)

In order not to exceed these exposure limits it is necessary to determine the ‘Compliance Boundary,’ that means the volume within which the EM ﬁeld radiated by 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 passive or active devices used in the installation.

The RF output power of this repeater is 25 watts.

The ﬁgures contained in this guide are based on the recommended limits for the general public and are obtained by ‘worst case’ numerical analysis. For a deﬁni- tive evaluation of any given installation, measurements should be made with an EM ﬁeld meter and a broadband 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 amplifiers 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 clearance distances speciﬁed, then these can cause reﬂections which will have an effect on the overall radiation pattern.

For any installation you need to consider ‘height clearance’ (i.e. the height above any place where persons may have access) and ‘front clearance’ (i.e. the distance in front of the antenna where the radiated ﬁeld may exceed the recommended 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 need to consider the distances between the antenna 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 been assumed.

Power EIRP Distance

clearance clearance

1 watt 1.6 watts 0.32 m 2.1 m 0.4 m

10 watts 16 watts 1 m 2.8 m 1.3 m

25 watts 40 watts 1.6 m 3.4 m 2 m

100 watts 160 watts 3.2 m 5 m 4 m

1 kW 1600 watts 10 m 12 m 13 m

• Installation with a yagi or directive type antenna

Exposure distance assumes that the predominant radiation 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 ﬁgures assume the worst case emission of constant carrier.

ABOUT CE

• Typical installation example

A UHF base station transmitter is to be installed on the roof of an ofﬁce.

The transmit power is 25 watts, there is 20 m of RG213 coaxial cable and the antenna is vertically polarised dipole.

The speciﬁcation 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 EIRP of 20 watts.

Referring to the table above for VHF/UHF vertical antennas, 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 lowest part of the antenna is at least 3 m above any point where the general public 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 question 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 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 recommendations.

If for any reason such minimum distances are impossible to guarantee then some type 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 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 transmit time during any 6 minute period is reduced, then the installation will be even further 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 approximately 70% for this reason.

CE Versions of the IC-FR3100/FR4100 which display the “CE” symbol on the serial number seal, comply with the essential requirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC.
