AVOID using or placing the transceiver in areas with temperatures below –10°C (+14°F) or above +60°C (+140°F). Be aware that temperatures on a vehicle’ s dashboard can exceed 80°C (+176°F), resulting in permanent damage to the transceiver if left there for extended periods. AVOID placing the transceiver in excessively dusty environments or in direct sunlight. AVOID placing the transceiver against walls or putting anything on top of the transceiver. This will obstruct heat dissipation. i BE CAREFUL! If a linear amplifier is connected, set the transceiver’s RF output power to less than the linear amplifier’s maximum input level, otherwise, the linear amplifier will be damaged. Use Icom microphones only (supplied or optional). Other manufacturer’s microphones have different pin assignments, and connection to the IC-718 may damage the transceiver.

Keep the shipping cartons. For radio communications, the antenna is of critical importance, along with output power and sensitivity. Select 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 your desired band. Of course, the transmission line should be a coaxial cable. For a description and a diagram of accessory equipment included with the IC-718, see ‘Supplied accessories’ on p. 1 of this manual. n Selecting a location Select a location for the transceiver that allows adequate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna elements, radios and other electro-magnetic sources. The base of the transceiver has an adjustable stand for desktop use. Set the stand to one of two angles depending on your operating conditions. C AUTION: Protect your transceiver from lightning by using a lightning arrestor. PL-259 CONNECTOR INSTALLATION EXAMPLE q 30 mm Coupling ring w 10 mm (soft solder) 10 mm Soft solder 1–2 mm Slide the connector body on and solder it. r To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, ground the transceiver through the GROUND 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. R WARNING: NEVER connect the [GND] terminal to a gas or electric pipe, since the connection could cause an explosion or electric shock. Strip the cable as shown at left. Soft solder the center conductor. solder solder e n Grounding Slide the coupling ring down. Strip the cable jacket and soft solder. Screw the coupling ring onto the connector body. 30 mm ≈ 9⁄8 in 10 mm ≈ 3⁄8 in 1–2 mm ≈ 1⁄16 in Antenna SWR Each antenna is tuned for a specified frequency range and SWR may be increased out-of-range. When the SWR is higher than approx. 2.0:1, the transceiver’s power drops to protect the final transistor. In this case, an antenna tuner is useful to match the transceiver and antenna. Low SWR allows full power for transmitting even when using the antenna tuner. The IC-718 has an SWR meter to monitor the antenna SWR continuously. 3 INSTALLATION AND CONNECTIONS n Required connections • Front panel i718 MODE FIL V/M 1 A=B 2 A/B 3 MW 4 M-CL 5 MV 6 7 SCN 8 VOX 9 .

The IC-718 VFO can store a frequency and an operating mode. You can call up a desired frequency to the VFO with the keypad or the memory transfer function (see p. 37). You can also change the frequency with the tuning dial and select the operating mode with the [MODE] switch or call up previously accessed frequency and modes with the band stacking register (p. 18). The IC-718 has two VFOs, specially suited for split frequency opration. The VFOs are called VFO A and VFO B. You can call up the desired VFO. • Differences between VFO mode and memory mode VFO MODE Each VFO shows a frequency and operating mode. If the frequency or operating mode is changed, the VFO automatically memorizes the new frequency or new operating mode. MEMORY MODE (pgs. 35–38) Each memory channel shows a frequency and operating mode like a VFO. Even if the frequency or mode is changed, the memory channel does not memorize the new frequency or operating mode. When the VFO is selected from another VFO or memory mode, the last-used frequency and operating mode for that VFO appears. When the memory channel is selected from another memory channel or VFO mode, the memorized frequency and operating mode appear. [EXAMPLE] [EXAMPLE] VFO is selected. Memory channel 1 is selected. The frequency is changed. The frequency is changed. Memory mode is selected. Another memory channel is selected. VFO is selected again. Memory channel 1 is selected again. Changed frequency (14.123 MHz) appears. 16 Changed frequency (14.123 MHz) does not appear and memorized frequency (14.100 MHz) appears instead.

Select a suitable condition according to your antenna system. qRemove the top cover of the AT-180. wSet the tuner switches to the desired positions according to the table below. SW Position Operation The tuner operating condition is set by S2 (default) described below. THROUGH INHIBIT The tuner tunes the antenna even when the antenna has poor SWR (up to VSWR 3:1 after tuning). In this case, manual tuning is necessary each time you change the frequency although the tuner automatically B starts tuning when the VSWR is higher than 3:1. This setting is called “through inhibit,” however, the tuner is set to “through” if the VSWR is higher than 3:1 after tuning. • AT-180 inside top cover S1 A S2 C S2 S1 D C B A TUNER SENSITIVE CONDITION The tuner tunes each time you transmit (except SSB mode). Therefore, the lowest SWR is obtained at any given time. For SSB mode, the same condition is as the “D” position below. NORMAL CONDITION The tuner tunes when the SWR is higher (default) than 1.5:1. Therefore, the tuner activates only when tuning is necessary.

The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals. In all cases any possible risk depends on the transmitter being activated for long periods. (actual recommendation limits are specified as an average of 6 minutes) Normally the transmitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts the transmitter after 1–2 minutes etc. As different exposure limits have been recommended for different frequencies, a relative table shows a guideline for installation considerations. Similarly some types of transmitter, SSB, CW, AM, etc. have a lower ‘average’ output power and the perceived risk is even lower. Below 10 MHz, the recommended limits are specified in terms of V/m or A/m fields as they are likely to fall within the near-field region. Similarly, at antennae may be physically short in terms of electrical length and that the installation will require some antenna matching device which can create high intensity magnetic fields. Analysis of such MF installations is best considered in association with published guidance notes such as the FCC OET Bulletin 65 Edition 97-01 and its annexes relative to amateur transmitter installations. Further information can be found at http://www.arrl.org/ Versions of the IC-718 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. • Typical amateur radio installation Exposure distance assumes that the predominant radiation pattern is forwards and that radiation vertically downwards is at unity gain (sidelobe suppresion 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 to 1.8 m. The figures assume the worst case emission of constant carrier.
