WORD DEFINITION

WARNING

CAUTION Equipment damage may occur.

NOTE

Place unit in a secure place to avoid inadvertent use by children.

During mobile operation, DO NOT operate the transceiver without running the vehicle’s engine. When transceiver power is ON and your vehicle’s engine is OFF, the vehicle’s battery will soon become exhausted.

Make sure the transceiver power is OFF before starting the vehicle. This will avoid possible damage to the transceiver by ignition voltage spikes.

Personal injury, ﬁre hazard or electric shock may occur.

If disregarded, inconvenience only. No risk or personal injury, fire or electric shock.

RNEVER let metal, wire or other objects touch any

internal part or connectors on the rear panel of the transceiver. 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 temperatures below –10°C (+14°F) or above +50°C (+122°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.

During maritime mobile operation, keep the transceiver and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications.

BE CAREFUL! The heatsink will become hot when operating the transceiver continuously for long periods.

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-756PROII may damage the transceiver.

INSTALLATION 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-756PROII, see ‘Supplied accessories’ on p. 1 of this manual.

■ 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.

■ Antenna connection

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.

When using 1 antenna, use the [ANT1] connector.

CAUTION: Protect your transceiver from lightning

by using a lightning arrestor.

Slide the coupling ring down. Strip the cable jacket and soft solder.

Strip the cable as shown at left. Soft solder the center conductor.

Slide the connector body on and solder it.

■ Grounding

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.

RWARNING: NEVER connect the [GND]

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

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-756PROII has an SWR meter to monitor the antenna SWR continuously.

FREQUENCY SETTING

■ VFO description

VFO is an abbreviation of Variable Frequency Oscillator, and traditionally refers to an oscillator.

The transceiver’s VFO is somewhat different. The VFO of the IC-756PROII acts like a computer’s window and can show one frequency and one operating mode.

You can call up a desired frequency to the VFO with the keypad, memo pad-read switch (see p. 56) or the memory transfer function (see p. 54). You can also change the frequency with the tuning dial and select the operating mode with the mode switches.

During dualwatch or split frequency operation, the sub VFO is functional (non-outline, non-spotted, larger frequency characters). While pushing [XFC] during split frequency operation, you can change the transmit readout frequency with the keypad, memo pad-read switch or the memory transfer function.

• Differences between VFO mode and memory mode

VFO MODE

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.

When a VFO is selected from another band or memory mode, the frequency and operating mode last used for that VFO appear.

[EXAMPLE]

VFO is selected.

MEMORY MODE (pgs. 51–55) 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 memory channel is selected from another memory channel or VFO mode, the memorized frequency and operating mode appear.

[EXAMPLE]

■ Twin PBT operation

General PBT (Passband Tuning) function electronically narrows the IF passband width by shifting the IF frequency to slightly outside of the IF ﬁlter passband to reject interference. This transceiver uses the DSP circuit for the PBT function. Moving both [TWIN PBT] controls to the same position shifts the IF. ➥ The LCD shows the passband width and shift fre-

quency graphically.

➥ Push [FILTER] for 1 sec. to enter the ﬁlter set mode.

Current passband width and shift frequency is displayed in the ﬁlter set mode screen.

➥ To set the [TWIN PBT] controls to the center posi-

tions, push [PBT CLR] for 1 sec.

See the diagram below for the order of selection.

The variable range depends on the passband width and mode. The edge of the variable range is half of the passband width, and PBT is adjustable in 25 or 50 Hz steps. These controls function as an IF shift control while in AM mode and when the RTTY ﬁlter is turned ON. Only the inner control may function in this case. IF shift is adjustable in 20/40 Hz steps in RTTY (RTTY

ﬁlter is turned ON) or 150/300/500 Hz steps in AM.

•[TWIN PBT] should normally be set to the center posi-

tions (PBT setting is cleared) when there is no interference.

•When PBT is used, the audio tone may be changed.

• Not available for FM mode.

•While rotating [TWIN PBT], noise may occur. This comes

from the DSP unit and does not indicate an equipment malfunction.

RECEIVE AND TRANSMIT

■ Split frequency operation

Split frequency operation allows you to transmit and receive in the same mode on two different frequencies. The split frequency operation is basically performed using 2 frequencies on the main and sub readouts.

The following is an example of setting 21.290 MHz for receiving and 21.310 MHz for transmitting.

q Set 21.290 MHz (USB) in VFO mode.

w Push [SPLIT] momentarily, then push [CHANGE]

for 1 sec.

•The quick split function is much more convenient for selecting the transmit frequency. See the next section for details.

•The equalized transmit frequency and “” appear on the LCD.

•“TX” appears to show the transmit frequency’s readout.

CONVENIENT

DIRECT SHIFT FREQUENCY INPUT

The shift frequency can be entered directly.

q Push [F-INP]. w Enter the desired shift frequency with the digit

keys.

• 1 kHz to 1 MHz can be set.

•When you require a minus shift direction, push [ •] in

advance.

e Push [SPLIT].

•The shift frequency is input in the sub readout and the split function is turned ON.

[EXAMPLE]

CONVENIENT

DUALWATCH FUNCTION

The dualwatch function is convenient for tuning the transmit frequency while monitoring both frequencies used for transmitting and receiving.

e Rotate the tuning dial while pushing [XFC] to set

the transmit frequency to 21.310 MHz.

•The transmit frequency can be monitored while pushing [XFC] or using dualwatch.

r Now you can receive on 21.290 MHz and transmit on

21.310 MHz.

To change the transmit and receive frequencies, push [CHANGE] to exchange the main and sub readouts.

CONVENIENT

SPLIT LOCK FUNCTION

Accidentally releasing the [XFC] switch while rotating the tuning dial changes the receive frequency. To prevent this, use both the split lock and dial lock functions to change the transmit frequency only. The split lock function cancels the dial lock function while pushing [XFC] during split frequency operation.

The dial lock’s effectiveness during split frequency operation can be selected in the set mode for both receive and transmit frequencies; or only the receive frequency. (p. 69)

RECEIVE AND TRANSMIT

When you ﬁnd a DX station, an important consideration is how to set the split frequency.

When you push the [SPLIT] switch for 1 sec., split frequency operation is turned ON, the sub readout is equalized to the main readout frequency and enters standby for transmit frequency input.

This shortens the time needed to start split frequency operation.

The quick split function is ON by default. For your convenience, it can be turned OFF in set mode. (p. 69) In this case, the [SPLIT] switch does not equalize the main and sub readout frequencies.

q Suppose you are operating at 21.290 MHz (USB)

in VFO mode.

w Push [SPLIT] for 1 sec.

• Split frequency operation is turned ON.

•The sub readout is equalized to the main readout fre-

quency.

•The sub readout enters standby for transmit frequency input.

e Rotate the tuning dial to set the transmit fre-

quency; or, input the transmit frequency using the keypad and [ENT]; or, input a shift frequency using the keypad and [SPLIT].

•The transmit frequency can be monitored while pushing [XFC] or using dualwatch.

PRACTICAL EXAMPLE

When you are searching for DX stations and you suspect that a DX station may say “up ‘X’ kHz” for their receive frequency:

OPERATION 1

q Push [SPLIT] for 1 sec. to standby for split opera-

tion.

w If the DX station’s operator says “up 10 kHz”:

• Push [1], [0] then [SPLIT].

• Or, rotate the tuning dial.

OPERATION 2

If the DX station’s operator says “down 5 kHz” before you enter standby for split operation:

➥ Push [F-INP], [•], [5] then [SPLIT].

•The split function is turned ON and “5 kHz down” fre-

quency is entered in the sub readout.

PRACTICAL EXAMPLE

When you receive a pile-up and you want to start split frequency operation to simplify picking out stations:

q Push [SPLIT] momentarily and push [CHANGE]

for 1 sec.

•The sub readout frequency is equalized to the main

readout frequency and “” appears.

w Rotate the tuning dial to set your receive fre-

quency in the main readout.

e Announce your receive frequency. r After you catch one of the calling stations’ call

signs, push and hold the PTT switch to respond.

•While pushing [XFC], you can monitor your transmit

frequency.

■ Preamp

The preamp amplifies received signals in the front end circuit to improve the S/N ratio and sensitivity. The transceiver has 2 preamp types.

➥ Push [P.AMP] to select one of 2 receive RF pre-

amps or to bypass them.

•“P. AMP1” activates 10 dB preamp for HF all bands.

•“P. AMP2” activates 16 dB high-gain preamp for

24 MHz band and above.

Regarding the use of the “P.AMP 2” (Pre-ampliﬁer 2)

The “P.AMP 2” is a high gain receive ampliﬁer. When the “P.AMP 2” is used during times of strong electric fields, distortion sometimes results. In such cases, use the transceiver with the “P.AMP 1” or “P.AMP OFF” setting.

The “P.AMP 2” is most effective when:

•Used on bands above 24 MHz and when electric ﬁelds are weak.

•Receive sensitivity is insufﬁcient during low gain, or

while using a narrow band antenna (such as small loop, a Beverage antenna or a short Yagi antenna, etc.) is used.

The transceiver has a total of 8 memory channels, 4 each for transmit and receive, of digital voice memories. A maximum message length of 15 sec. can be recorded in each receive channel, and a total message length of 90 sec. can be recorded in transmit channels.

• Recording a received audio

q Push [EXIT/SET] several times to close a multi-

function screen, if necessary.

w Select the desired mode by pushing [SSB],

[CW/RTTY] or [AM/FM].

e Push [(F-2)VOICE] to call up the voice recorder

screen.

•If the transmit voice memory channel (T1–T4) appears, push [(F-5)T/R] to select receive voice memory channel.

r Push the desired memory channel switch,

[(F-1)R1] –[(F-4)R4], for 1 sec. to start recording.

•“REC” ﬂashes and the recording timer counts up.

•The operating frequency, mode and current time are

programmed as the memory names automatically.

• Previously recorded contents are cleared.

Providing a transmission memory is very convenient for repeated CQ and number transmissions at contest times, as well as when making consecutive calls in DX’pedition.

• Playing the recorded audio

q Push [EXIT/SET] several times to close a multi-

function screen, if necessary.

w Push [(F-2)VOICE] to call up the voice recorder

screen.

•If the transmit voice memory channel (T1–T4) appears, push [(F-5)T/R] to select receive voice memory channel.

e Push the desired memory channel switch,

[(F-1)R1] –[(F-4)R4], momentarily to playback.

•“PLAY” appears.

t Push the selected memory channel switch,

[(F-1)R1] –[(F-4)R4], again to stop recording.

• Recording is automatically terminated after 30 min.

IMPORTANT!

Push one of [(F-1)R1]–[(F-4)R4] to stop recording before, or when 15 sec. has passed from the start of recording. The voice recorder memory records the 15 sec. (max.) of audio before one of [(F-1)R1]–[(F-

4)R4] is pushed. For example, when recording 20 sec. of audio, the ﬁrst 5 sec. audio will be over-recorded with the last 5 sec., so that the total of audio recorded is 15 sec. only.

y Push [EXIT/SET] twice to exit the voice memory

screen.

r Push the selected memory channel switch,

[(F-1)R1] –[(F-4)R4], again to stop playback if de- sired.

•Playback is terminated automatically when all of the recorded contents in the channel are played, or after 15 sec.

■ Automatic antenna selection

The transceiver covers 0.1–60 MHz over 10 bands. Each band key has a band memory which can memorize a selected antenna (ANT1, ANT2, ANT1/RX antenna and ANT2/RX antenna). When you change the operating frequency beyond a band, the previously used antenna is automatically selected for the new band. This function is convenient when you use 2 or 3 antennas.

To use the band memory, enter set mode and conﬁrm that “Auto” is selected as the [ANT] switch item. (p. 70)

•When OFF is selected, the [ANT] switch does not function and [ANT1] is always selected.

•When “Manual” is selected, the [ANT] switch functions, however, band memory does not function. In this case, you must select an antenna manually.

•When “Auto” is selected (default setting), the antenna tuner ON/OFF condition is also memorized in the band memory.

•When “Auto” or “Manual” is selected, the antenna tuner ON/OFF condition is consistent with the [ANT] switch.

• Antenna switch selection example

Under the following condition, “Auto” should be selected as the [ANT] switch set mode item.

- When you use 2 antennas.

Under the following conditions, “Manual” should be selected as the [ANT] switch set mode item.

- When using 1 antenna.

- When using an external antenna selector for more than 3 antennas (except for receive antenna).

- When using an external antenna tuner.

RECEIVE AND TRANSMIT

A repeater ampliﬁes received signals and retransmits them at a different frequency. When using a repeater, the transmit frequency is shifted from the receive frequency by an offset frequency. A repeater can be accessed using split frequency operation with the shift frequency set to the repeater’s offset frequency.

For accessing a repeater which requires a repeater tone, set the repeater tone frequency in set mode as described below.

q Set the offset frequencies (HF, 50 MHz) and turn

ON the quick split function in set mode (others) in advance. (p. 69)

w Push [VFO/MEMO] to select VFO mode.

e Push the desired band key. r Push [AM/FM] several times to select FM mode. t Set the receive frequency (repeater output fre-

quency).

• Setting the repeater tone

Some repeaters require subaudible tones to be accessed. Subaudible tones are superimposed over your normal signal and must be set in advance. The transceiver has 50 tones from 67.0 Hz to 254.1 Hz.

Each memory channel can store an independent setting.

q Select FM mode. w Push [TONE] for 1 sec. to enter tone set mode. e Push [(F-1)∫] to select the repeater tone item. r Rotate the tuning dial to select the desired re-

peater tone frequency.

■ Antenna tuner operation

[TUNER] switch

Push [TUNER] for 1 sec.

RECEIVE AND TRANSMIT

The internal automatic antenna tuner matches the transceiver to the connected antenna automatically. Once the tuner matches an antenna, the variable capacitor angles are memorized as a preset point for each frequency range (100 kHz steps). Therefore, when you change the frequency range, the variable capacitors are automatically preset to the memorized point.

TUNER OPERATION

➥ Push the [TUNER] switch to turn the internal an-

tenna tuner ON. The antenna is tuned automatically when the antenna SWR is higher than 1.5:1.

• When the tuner is ON, the [TUNER] switch lights.

MANUAL TUNING

During SSB operation at low voice levels, the internal tuner may not be tuned correctly. In such cases, manual tuning is helpful.

➥ Push [TUNER] for 1 sec., to start manual tuning.

•A side tone is emitted and [TUNER] blinks while tuning.

•If the tuner cannot reduce the SWR to less than 1.5:1

after 20 sec. of tuning, the [TUNER] switch indicator goes out.

CAUTION:

NEVER transmit with the tuner ON

when no antenna is connected. This will damage the transceiver. Be careful of the antenna selection.

AUTOMATIC TUNER START (HF bands only)

If you want to deactivate the tuner under conditions of VSWR 1.5:1 or less, use the auto tuner start function and turn the tuner OFF. This function activates the tuner automatically when the SWR exceeds 1.5:1.

This function is turned ON in set mode. (p. 70).

NOTES:

• If the tuner cannot tune the antenna

Check the following and try again:

• the [ANT] connector selection.

• the antenna connection and feedline.

•the unaltered antenna SWR. (Less than 3:1 for HF bands;

Less than 2.5:1 for 50 MHz band)

•the transmit power. (8 W for HF bands; 15 W for 50 MHz band)

• the power source voltage/capacity.

If the tuner cannot reduce the SWR to less than 1.5:1 after checking the above, perform the following:

• repeat manual tuning several times.

• tune with a 50 Ω dummy load and re-tune the antenna.

• turn power OFF and ON.

•adjust the antenna cable length.

(This is effective for higher frequencies in some cases.)

PTT TUNER START

The tuner is always tuned when the PTT is pushed after the frequency is changed (more than 1% from last-tuned frequency). This function removes the “push and hold [TUNER]” operation and activates for the ﬁrst transmission on a new frequency.

This function is turned ON in set mode. (p. 70).

• Tuning a narrow bandwidth antenna

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

Suppose you have an antenna which has an SWR of

1.5:1 at 3.55 MHz and an SWR of 3:1 at 3.8 MHz.

q Push [TUNER] to turn the antenna tuner ON. w Select CW mode. e Turn OFF the break-in function. (p. 5) r Push [TRANSMIT] to set to the transmit condition. t Set 3.55 MHz and key down. y Set 3.80 MHz and key down. u Push [TRANSMIT] to return to the receive condition.

■ Optional external tuner operation

•AH-4/AH-3 HF AUTOMATIC ANTENNA TUNER

The AH-4 matches the IC-756PROII to a long wire antenna more than 7 m/23 ft long (3.5 MHz and above).

The AH-3 matches the IC-756PROII to a long wire antenna more than 3 m/10 ft long (3.5 MHz and above) or more than 12 m/40 ft long (1.8 MHz and above)

• See p. 19 for the transceiver and AH-4/AH-3 connection.

•See the AH-4/AH-3 instruction manual for AH-4/AH-3 in-

stallation and antenna connection details.

AH-4/AH-3 setting example:

•When connecting the AH-4/AH-3, the antenna connector assignments are [ANT2] for the internal tuner and [ANT1] for the AH-4/AH-3. The antenna indicator in the LCD displays “ANT1(EXT)” when the AH-4/AH-3 is connected and selected.

•The AH-3 can be used for HF bands only. It can-

not be used for the 50 MHz band.

• AH-4/AH-3 operation

Tuning is required for each frequency. Be sure to re-tune the antenna before transmitting when you change the frequency—even slightly.

q Set the desired frequency in an HF or 50 MHz

band for use with the AH-4. Set the desired frequency in an HF band for use with the AH-3.

•The AH-4/AH-3 will not operate on frequencies outside of ham bands.

w Push [TUNER] for 1 sec.

• The [TUNER] light blinks while tuning.

RWARNING: HIGH VOLTAGE!

NEVER touch the antenna element while tuning

or transmitting.

NEVER operate the AH-4/AH-3 without an antenna wire. The tuner and transceiver will be damaged.

NEVER operate the AH-4/AH-3 when it is not grounded.

Transmitting before tuning may damage the transceiver. Note that the AH-4/AH-3 cannot tune when using a 1⁄2 λ long wire or multiple of the operating fre- quency.

• ANTENNA TUNER OF THE IC-PW1

When using an external antenna tuner such as the IC-PW1’s tuner, tune with the external antenna tuner, while the internal tuner is turned OFF. After tuning is completed, turn the internal tuner ON. Otherwise, both tuners tune simultaneously and correct tuning may not be obtained.

e The [TUNER] light lights constantly when tuning is

complete.

•When the connected wire cannot be tuned, the [TUNER] light goes out and the AH-4/AH-3 is bypassed. At that point the antenna wire connection rout is to the transceiver directly, and not via the AH-4/AH-3 antenna tuner.

To bypass the AH-4/AH-3 manually, push [TUNER].

See the instruction manual included with each antenna tuner for their respective operations.

MEMORY OPERATION

■ Frequency transferring

The frequency and operating mode in a memory channel can be transferred to the VFO.

• Transferring in VFO mode

This is useful for transferring programmed contents to VFO.

q Select VFO mode with [VFO/MEMO]. w Select the memory channel to be transferred with

[Y]/[Z].

•Memory channel screen is convenient for selecting the desired channel.

•Memory channel contents appear in the memory channel readout (below the frequency readout).

•“--.---.--” appears if the selected memory channel is a blank channel. In this case transferring is impossible.

e Push [VFO/MEMO] for 1 sec. to transfer the fre-

quency and operating mode.

•Transferred frequency and operating mode appear on the frequency readout.

Frequency transferring can be performed in either VFO mode or memory mode.

TRANSFERRING EXAMPLE IN VFO MODE

Operating frequency : 21.320 MHz/USB (VFO) Contents of M-ch 16 : 14.018 MHz/CW

• Transferring in memory mode

This is useful for transferring frequency and operating mode while operating in memory mode.

When you have changed the frequency or operating mode in the selected memory channel:

• Displayed frequency and mode are transferred.

•Programmed frequency and mode in the mem-

ory channel are not transferred, and they remain in the memory channel.

q Select the memory channel to be transferred with

[Y]/[Z] in memory mode.

•And, set the frequency or operating mode if required.

MEMORY OPERATION

■ Memo pads

The transceiver has a memo pad function to store frequency and operating mode for easy write and recall. The memo pads are separate from memory channels.

The default number of memo pads is 5, however, this can be increased to 10 in set mode if desired. (p. 71)

•Writing frequencies and operating modes into memo pads

You can simply write the accessed readout frequency and operating mode by pushing [MP-W].

When you write a 6th frequency and operating mode, the oldest written frequency and operating mode are automatically erased to make room for the new settings.

Each memo pad must have its own unique combination of frequency and operating mode; memo pads having identical settings cannot be written.

Memo pads are convenient when you want to memorize a frequency and operating mode temporarily, such as when you ﬁnd 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 transceiver’s memo pads instead of relying on hastily scribbled notes that are easily misplaced.

•Calling up a frequency from a memo pad

You can simply call up the desired frequency and operating mode of a memo pad by pushing [MP-R] several times.

• Both VFO and memory modes can be used.

•The frequency and operating mode are called up, starting

from the most recently written.

When you call up a frequency and an operating mode from memo pads with [MP-R], the previously dis-

played frequency and operating mode are automatically stored in a temporary pad. The frequency and operating mode in the temporary pad can be recalled by pushing [MP-R] several times.

•You may think there are 6 memo pads because 6 different

frequencies (5 are in memo pads and 1 is in the temporary pad) are called up by [MP-R].

If you change the frequency or operating mode called up from a memo pad with the tuning dial, etc., the frequency and operating mode in the temporary pad are erased.

■ Scan types

•The scan function can be used on the main readout only.

•You can operate a scan while operating on a frequency using

the dualwatch or split functions. See p. 31 for details.

■ Preparation

• Channels

For programmed scan:

Program scan edge frequencies into scan edge memory channels P1 and P2.

For ∂F scan:

Set the ∂F span (∂F scan range) in the scan screen.

For memory scan:

Program 2 or more memory channels except scan edge memory channels.

For select memory scan:

Designate 2 or more memory channels as select memory channels. To designate the channel as a select memory channel, choose a memory channel, then push [(F-3)SELECT] in the scan screen (memory mode) or in the memory channel screen.

• Scan resume ON/OFF

You can select the scan to resume or cancel when detecting a signal, in set mode. Scan resume ON/OFF must be set before operating a scan. See p. 61 for ON/OFF setting and scan resume condition details.

• Scan speed

Scan speed can be selected from 2 levels, high or low, in set mode. See p. 61 for details.

• Squelch condition

INSTALLATION NOTES

For amateur base station installations it is recommended that the forwards clearance in front of the antenna 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.

ABOUT CE

EIRP clearance heights by frequency band

1 Watts 2.1 m 10 Watts 2.8 m 25 Watts 3.4 m

100 Watts 5 m

1000 Watts 12 m

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 speciﬁed in terms of V/m or A/m ﬁelds as they are likely to fall within the near-field region. Similarly, the antennae may be physically short in terms of electrical length and that the installation will require some antenna matching device which can create local, 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. The EC recommended limits are almost identical to the FCC speciﬁed ‘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/.

• Typical amateur radio installation

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 to 1.8 m.

The ﬁgures assume the worst case emission of constant carrier.

Forward clearance, EIRP by frequency band

100 Watts 2 m

1000 Watts 6.5 m 10,000 Watts 20 m 100,000 Watts 65 m

In all cases any possible risk depends on the transmitter being activated for long periods. (actual recommendation limits are speciﬁed 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 the transmitter after 1–2 minutes etc.

Similarly some types of transmitter, SSB, CW, AM etc. have a lower ‘average’ output power and the assessed risk is even lower.

Versions of the IC-756PROII 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.

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

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