INSTRUCTION MANUAL

VHF/UHF FM TRANSCEIVER

i207H

This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

IMPORTANT

READ ALL INSTRUCTIONS carefully and completely before using the transceiver.

SAVE THIS INSTRUCTION MANUAL—This instruction manual contains important operating instructions for the IC-207H.

EXPLICIT DEFINITIONS

The explicit definitions below apply to this instruction manual.

	WORD	DEFINITION
	RWARNING	Personal injury, fire hazard or electric shock
		may occur.
	CAUTION	Equipment damage may occur.
	NOTE	If disregarded, inconvenience only. No risk
		of personal injury, fire or electric shock.

i

CAUTIONS

RWARNING! NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock.

RWARNING! NEVER operate the transceiver while driving a vehicle. Safe driving requires your full attention— anything less may result in an accident.

NEVER connect the transceiver to a power source of more than 16 V DC. This connection will ruin the transceiver.

NEVER connect the transceiver to a power source using reverse polarity. This connection will ruin the transceiver.

NEVER cut the DC power cable between the DC plug and fuse holder. If an incorrect connection is made after cutting, the transceiver might be damaged.

NEVER place the transceiver where normal operation of the vehicle may be hindered or where it could cause bodily injury.

NEVER let objects impede the operation of the cooling fan on the rear panel.

DO NOT push the PTT when not actually desiring to transmit.

DO NOT allow children to play with any radio equipment containing a transmitter.

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.

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

AVOID using or placing the transceiver in areas with temperatures below –10°C (+14°F) or above +60°C (+140°F) or in areas subject to direct sunlight, such as the dashboard.

AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they can damage the transceiver surfaces.

USE Icom microphones only (supplied or optional). Other manufacturer’s microphones have different pin assignments and may damage the transceiver if attached.

Note that in this manual, sections beginning with a microphone icon (as at left) designate operation via the HM-98 microphone.

■ Location

Select a location which can support the weight of the transceiver and does not interfere with driving in any way. We recommend the locations shown in the diagram below.

NEVER place the transceiver or remote controller where normal operation of the vehicle may be hindered or where it could cause bodily injury.

NEVER place the transceiver or remote controller where air bag deployment may be obstructed.

DO NOT place the transceiver or remote controller where hot or cold air blows directly onto it.

AVOID placing the transceiver or remote controller in direct sunlight.

• EXAMPLE INSTALLATION LOCATIONS

INSTALLATION 2

■ Single body installation

Drill 4 holes where the mounting bracket is to be installed.

•Approx. 5.5–6 mm (3⁄16 in) when using nuts; approx. 2–3 mm (1⁄16 in) when using self-tapping screws.

Insert the supplied screws, nuts and washers through the mounting bracket and tighten.

■ Antenna installation

D Antenna location

To obtain maximum performance from the transceiver, select a high-quality antenna and mount it in a good location. A nonradial antenna should be used when using a magnetic mount.

Trunk-mount Roof-mount antenna antenna (Drill a hole or use a magnetic mount.)

Gutter-mount antenna

D Antenna splitter

You can use a dual band antenna because a duplexer is installed in the transceiver. However, an external duplexer must be connected when using a separate antenna for each band.

•The operating band cannot be changed unless you are in VFO mode (see right).

Push [BAND] one or more times to select the de- BAND sired operating band.

D VFO and memory modes

The transceiver has 2 normal operating modes: VFO mode and memory mode.

Push [V/MHz] to select VFO mode when the transceiver is not in VFO mode.

•If VFO mode is already selected, the digits below 100 kHz disappear. In this case, push [V/MHz] again (or push twice depending on version).

■ Lock functions

To prevent accidental frequency changes and unnecessary function access, use the lock function. The transceiver has 2 different lock functions.

D Frequency lock

This function locks the tuning dial and switches electronically and can be used together with the microphone lock function.

Push and hold LOCK until “L” appears in the memory channel readout to activate the function.

• To cancel the function, push and hold LOCK until “L” disappears.

•[PTT], [MONI], [VOL] and [SQL] can be used while the frequency lock function is in use. Also, TONE-1, TONE-2, DTMF tones or DTMF memory contents can be transmitted from the microphone.

Push [FUNC] then [A16 KEYLOCK] to toggle the microphone keypad lock function ON and OFF.

•[PTT] and the 7 keys on the upper half of the microphone can be used.

•All switches on the transceiver can be used.

•The keypad lock function is released when the power is turned OFF then ON again.

3 SETTING A FREQUENCY

■ Using the tuning dial

Push [BAND] to select the desired band, if necessary.

Rotate the tuning dial to set the frequency.

•If VFO mode is not selected, push the [V/MHz] to select VFO mode.

•Frequency changes according to the selected tuning steps. (p. 18)

For the 1 MHz frequency setting, rotate the tuning dial after pushing [V/MHz].

•Pushing [V/MHz] for 1 sec. starts a scan function. If this happens, push [V/MHz] again to stop the scan.

H I		The display shows that the 1 MHz
	1	5 9
		tuning step is selected for the

VHF band.

■ Using [Y]/[Z] switches

Push [Y] or [Z] to set the selected band’s fre- YZ quency.

•If VFO mode is not selected, push [VFO] to select it.

•Frequency changes according to the selected tuning steps. (p. 18)

•Pushing [Y] or [Z] for more than 0.5 sec. activates a scan. If this happens, push [Y] or [Z] again to stop it.

NOTE: 1 MHz steps cannot be used via the [Y]/[Z] switches.

■ Tuning step selection						SET
				USING SET MODE
Tuning steps are the minimum frequency change increments						B
when you rotate the tuning dial or push the [Y] or [Z]
switches on the microphone. The following tuning steps are
available:
• 5 kHz	• 10 kHz	• 12.5 kHz	• 15 kHz
• 20 kHz	• 25 kHz	• 30 kHz	• 50 kHz

NOTE: For convenience, select a tuning step that matches the frequency intervals of repeaters in your area.

Push [BAND] to select the desired band, if necessary.

Push [V/MHz] to select VFO mode if another mode has been selected.

Push [SET] one or more times until “tS” appears as shown below.

•Pushing [MONI] reverses the order of selection.

•Cancel the DTMF memory function in advance. (p. 48)

Rotate the tuning dial to select the tuning step.Push [V/MHz] to exit set mode.

The frequency can be directly set via numeral

	ENT	keys on the microphone.

Ä Push [BAND] to set the operating band, if necessary. Å Push [VFO] to select VFO mode.

Ç Push [ENT] to activate the keypad for digit input.

ÉPush 5 keys to input a frequency.

•When a digit is mistakenly input, push [ENT] to clear the input, then input from the 1st digit.

•Pushing [CLR] clears input digits and retrieves the frequency.

Ñ Push [Y] or [Z] to make adjustments below the 10 kHz digit, if desired.

[EXAMPLE]: Setting the frequency to 145.360 MHz.
