technician for help.

Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regula-

tions. DO NOT use harsh solvents such as benzine or alcohol when cleaning, as they will damage the trans-

ceiver surfaces. DO NOT push the PTT switch when you dont actu-

ally desire to transmit. DO NOT use or place the transceiver in areas with temperatures below 0C (+32F) or above +50C

(+122F). DO NOT place the transceiver in excessively dusty environments or in direct sunlight. DO NOT place the transceiver against walls or putting anything on top of the transceiver. This may overheat the transceiver. Always place unit in a secure place to avoid inadver-

tent use by children.

If you use a linear amplifier, set the transceivers RF output power to less than the linear amplifiers maximum input level, otherwise, the linear amplifier will be damaged.

The rear panel will become hot when operating the transceiver continuously for long periods of time. USE only the specified microphone. Other manufac-

turers microphones have different pin assignments, and connection to the IC-7410 may damage the transceiver or microphone. During maritime mobile operation, keep the trans-

ceiver and microphone as far away as possible from the magnetic navigation compass to prevent errone-

ous indications. Turn OFF the transceivers power and/or disconnect the DC power cable when you will not use the trans-

ceiver for long period of time. PRECAUTIONS R WARNING HIGH RF VOLTAGE! NEVER attach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn. R WARNING! NEVER operate the transceiver with a headset or other audio accessories at high volume levels. Hearing experts advise against continu-

ous high volume operation. If you experience a ringing in your ears, reduce the volume or discontinue use. R WARNING! NEVER operate or touch the transceiver with wet hands. This may result in an electric shock or damage to the transceiver. R WARNING! NEVER apply AC power to the

[DC13.8V] socket on the transceiver rear panel. This could cause a fire or damage the transceiver. R WARNING! NEVER apply more than 16 V DC to the [DC13.8V] socket on the transceiver rear panel, or use reverse polarity. This could cause a fire or damage the transceiver. R WARNING! NEVER let metal, wire or other objects protrude into the transceiver or into connectors on the rear panel. This may result in an electric shock. R WARNING! Immediately turn OFF the trans-

ceiver power and remove the power cable if it emits an abnormal odor, sound or smoke. Contact your Icom dealer or distributor for advice.

put the transceiver in any unstable place (such as on a slanted surface or vibrated place). This may cause injury and/or damage to the transceiver.

NEVER change the internal settings of the transceiver. This may reduce transceiver perfor-

mance and/or damage to the transceiver. In particular, incorrect settings for transmitter circuits, such as output power, idling current, etc., might damage the expensive final devices. The transceiver warranty does not cover any prob-

lems caused by unauthorized internal adjustment.

NEVER block any cooling vents on the top, rear, sides or bottom of the transceiver.

NEVER expose the transceiver to rain, snow or any liquids.

NEVER install the transceiver in a place without adequate ventilation. Heat dissipation may be reduced, and the transceiver may be damaged. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 ii 3 ..................................... 2334

* When the SEND terminal controls an inductive load (such as a relay), a counter-electromotive force can cause the transceivers malfunction or damage. To prevent this, we recommend adding a switching diode, such as an 1SS133, on the load side of the circuit to the counter-electromotive force absorption. When the diode is added, a switching delay of the relay may occur. Be sure to check its switching action before operation. Switching diode

Select a location for the transceiver that allows ade-

quate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna ele-

ments, radios and other electromagnetic sources. The base of the transceiver has adjustable feet for desktop use. Set the feet to one of two angles, to meet your operating preference.

For radio communications, the antenna is of criti-

cal importance, along with output power and receiver sensitivity. Select a well-matched 50 antenna and coaxial cable feedline. We recommend 1.5:1 or bet-

ter of Voltage Standing Wave Ratio (VSWR) on your operating bands. The transmission line should be a coaxial cable. When using a single antenna, use the [ANT1] con-

nector.

Protect your transceiver from lightning by using a lightning arrestor. Antenna SWR Each antenna is tuned for a specified frequency range and the SWR usually increases outside the range. When the SWR is higher than approx. 2.0:1, the transceiver automatically reduces the TX power to protect the final transistors. In that case, an antenna tuner is useful to match the transceiver and antenna. Low SWR allows full power for transmit-

ting. The IC-7410 has an SWR meter to continuously monitor the antenna SWR.

To prevent electrical shock, television interference

(TVI), broadcast interference (BCI) and other prob-

lems, ground the transceiver using the GROUND ter-

minal on the rear panel. For best results, connect the heaviest possible gauge wire or strap to a long ground rod. Make the distance between the [GND] terminal and ground as short as possible. R connect the [GND] ter-

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

est stored entry is automatically erased, to make room for the new data. Memo pads are convenient when you want to memo-

rize the displayed data temporarily, such as when you nd a DX station in a pile-up, or when a desired station is busy for a long time and you want to temporarily search for other stations. Use the transceivers memo pads instead of relying on hastily scribbled notes that are easily misplaced.

The IC-7410 has 2 antenna connectors for the HF/50 MHz bands, [ANT1] and [ANT2]. You can memorize the antenna for each operating band the IC-7410 covers. When you change the operating band, the previously set antenna connector for that band is automatically selected. (See below) This function is especially convenient when you use 2 antennas for HF and 50 MHz band operation. To use the band memory, set the [ANT] Switch item to Auto in the Set mode. (p. 87)

The internal automatic antenna tuner automatically matches the transceiver to the selected antenna. After the tuner matches an antenna, the variable capacitor settings are memorized as a preset point for each fre-

quency range (100 kHz steps). Therefore, when you change the frequency range, the variable capacitors are automatically preset to the memorized setting.

tenna the second time.

Some antennas, especially for the low bands, have a narrow bandwidth. These antennas may not be tuned beyond the edge of their operating bandwidth, therefore, manually tune such an antenna as follows:

A very accurate frequency counter is required to cali-

brate the frequency of the transceiver. However, a rough check may be performed by receiving radio sta-

tion WWV, WWVH, or other standard frequency sig-

nals.

The IC-7410 has been thoroughly ad-

justed and tested at the factory before being shipped. You should not have to re-calibrate it. q Push [SSB] once or twice to select the USB mode. w Push [PBT-CLR] for 1 second to clear the PBT set-

tings and make sure that the RIT/TX function is turned OFF. e Set the frequency to the standard frequency station

minus 1 kHz.

When receiving WWV or WWVH (at 15.000.00 MHz) as a standard frequency, set the operating frequency for 14.999.00 MHz.

r Hold down [MENU] for 1 second to enter the Set mode. t Push [Y](F-1) or [Z](F-2) to select Calibration Marker.

If a fuse blows, or the transceiver stops functioning, nd the source of the problem, and repair it. Then re-

place the damaged fuse with a new, adequately rated fuse.

Turn OFF the power and disconnect the DC power cable from the transceiver before per-

forming any work on the transceiver. Otherwise, there is danger of electric shock, equipment dam-

age and/or re injury, D Refer to the gure illustrated to the right for the DC power cable fuse replacement. D Except for the power amplier, the 13.8 V DC from the DC power cable is applied to all units in the IC-7410, through the circuitry fuse. This fuse is located in the PA unit. q Remove the top cover. (p. 94) w Remove the 22 screws, then remove the PA shield-

ing plate as shown to the right. e Remove the speaker cable from the connector on the PA unit as shown to the right. r Replace the circuitry fuse as shown in the diagram to the right. t Replace the speaker cable, PA shielding plate, top cover and screws to their original position. R DO NOT pull the speaker cable when removing the PA shielding plate, or DO NOT put the speaker cable under the PA shielding plate when replacing it. This could damage the trans-

ceiver. 99 The IC-7410 has two fuse types installed for trans-

ceiver protection.

mended that the forward clearance in front of the an-

tenna array is calculated relative to the EIRP (Effective Isotropic Radiated Power). The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals. As different exposure limits have been recommended for different frequencies, a relative table shows a guideline for installation considerations. Below 30 MHz, the recommended limits are specied in terms of V/m or A/m elds as they are likely to fall within the near-eld region. Similarly, the antennas may be physically short in terms of electrical length and that the installation will require some antenna matching device which can create local, high inten-

sity magnetic elds. Analysis of such MF installations is best considered in association with published guid-

ance notes such as the FCC OET Bulletin 65 Edition 97-01 and its annexes relative to amateur transmitter installations. The EC recommended limits are almost identical to the FCC specied uncontrolled limits and tables exist that show pre-calculated safe distances for different antenna types for different frequency bands. Further information can be found at http://www.arrl.org/.

Exposure distance assumes that the predominant ra-

diation pattern is forward 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 gures assume the worst case emission of a con-

stant carrier. For the bands 10 MHz and higher the following power density limits have been recommended:

1050 MHz 2 W/sq m

1 Watts 2.1 m 10 Watts 2.8 m 25 Watts 3.4 m 100 Watts 5 m 12 m 1000 Watts

100 Watts 1000 Watts 10,000 Watts 100,000 Watts 2 m 6.5 m 20 m 65 m 113 In all cases any possible risk depends on the trans-

mitter being activated for long periods. (actual recom-

mendation limits are specied as an average during 6 minutes) Normally the transmitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts off the transmitter after 12 minutes etc. Similarly some modes of transmission, SSB, CW, AM etc. have a lower average output power and the as-

sessed risk is even lower. Versions of the IC-7410 which display the CE symbol on the serial number label, comply with the essential requirements of the European Radio and Telecommunica-

tion Terminal Directive 1999/5/EC. This warning symbol indicates that this equipment operates in non-harmonised frequency 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 program-

ming of this radio, to comply with national licensing requirement.

Phone : +81 6 6793 8424 Fax: +81 6 6793 3336 e-mail: world_support@icom.co.jp URL : http:/Avww.icom.co.jpAworld Date: November 30, 2010 To Whom It May Concern Subject: Scanning Receiver Statement Applicant: Icom Incorporated Product: Scanning Receiver Model: IC-7410 FCC ID: AFJ318200 The equipment under application herein incorporates a scanning receiver. Accordingly, 15.121 of the Commissions rules applies. The equipment under application herein is incapable of operating (tuning), or being readily altered by the user to operate within the frequency bands allocated to the Domestic Public cellular Radio Telecommunications Service (Cellular Radio Service). The equipment is also incapable of converting digital cellular transmissions to analog voice audio. The receiver portion of the equipment under application herein scans 0.03-60.000MHz, the receiver does not scan the bands used by the Cellular Radio Service, 824-849 and 869-894MHz. The receiver portion of the equipment under application cannot be altered to enable it to scan the Cellular Radio Service bands by means of clipping the leads of or installing a diode, resistor and/or jumper wire, or other such simple component. Nor can the receiver be made to scan the Cellular Radio Service bans by replacing a plug-in semiconductor chip, since no such plug-in chips are utilized. The semiconductor chips that are utilized in the equipment cannot be erased and reprogrammed. The radio design of the tuning, control and filtering circuitry on the receiver is controlled by the serial data from the firmware code in the microprocessor, which is built-in by the microprocessor manufacture as a part of the internal design of the processor. Since the processor information is inaccessible to the user (Even Icom peoples), if someone attempt modifying circuitry without the knowledge of the firmware code, the radio simply will fail to operate. In view of the above, the equipment complies with 15.121 of the Commission rules. Sincerely Icom Incorporated Takayuki Watanabe General Manager of Quality Department
