VHF/UHF FM TRANSCEIVER

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.

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.

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 tem-

peratures 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.

■ 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.

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.

D Antenna connector

The antenna uses a PL-259 connector.

■ What is a scratch pad

memory?

During VFO operation, the transceiver automatically memo­rizes operating frequency information, separate from regular
memory channels, when transmitting on a new frequency.
The 5 previously operated frequencies for each band can be
recalled (L1 to L5 appear for simplex frequencies; r1 to r5 ap­pear for duplex frequencies.

NOTE: When memory mode is selected, the frequency is
not programmed into a scratch pad.

■ Calling up a scratch pad

memory

➀ Select the call channel by pushing [M/CALL] once or twice.

(A large “C” appears.)

• To transmit on the scratch pad memory, select the desired band

in advance.

➁ Rotate the tuning dial to select a scratch pad memory.

• Previously transmitted frequency and one of “L1–L5” appears for
simplex memories (rotate [DIAL] left); one of “r1–r2” appears for
duplex memories (rotate [DIAL] right).

• When first applying power or after CPU resetting, scratch pad
memories contain no data and therefore cannot be accessed.

➂ Push [V/MHz] or [M/CALL] to exit the scratch pad memory.

• The 5th scratch pad memory will be cleared when trans­mitting on a new frequency. If the transmit frequency is
already stored in a scratch pad memory, the scratch pad
memory is not cleared but the order is changed.

• When transmitting on a scratch pad memory, the scratch
pad memory becomes the 1st scratch pad memory and
the order is changed.

Attach the EX-1759 to a suitable location for receiving in­frared signals and where it can be connected to a cable, e.g.
the console, etc.

NOTE: DO NOT attach the EX-1759 where it will be sub­ject to direct sunlight as it cannot detect infrared signals
under such conditions.

• Optional infrared sub receiver

An optional EX-1513

INFRARED SUB RECEIVER

is available to
increase the remote control reliability and extend the control­lable area. Connect the EX-1513 to the inside connector of
the EX-1759.

NOTE: The supplied microphone, HM-98, can be con­nected and used with the EX-1759, however, the optional

connector during data transmission, otherwise the data
signal and voice signal are simultaneously transmitted.

For 9600 bps operation—

• When the transceiver is set for 9600 bps data transmis-

sion in INTIAL SET MODE, the microphone signal is au­tomatically cut. Therefore, it is not necessary to
disconnect the microphone plug from the connector in
this case.

• When pushing [PTT] during data transmission, data
transmission is interrupted and voice signals have prior­ity.

NOTE:

• Read the instructions supplied with your TNC carefully
before attempting packet operation with the IC-207H.

• Pin t AF OUT is for 1200 bps operation only. This pin
cannot be used for 9600 bps operation.

signal coming from the TNC is applied exclusively to the in­ternal limiter circuitry to automatically maintain band width.

NEVER apply data levels from the TNC of over 0.6 Vp-p, oth­erwise the transceiver will not be able to maintain the band
width and may possibly interfere with other stations.

1. When using a level meter or synchroscope, adjust the TX
audio output level (

DATA IN

level) from the TNC as follows.

0.4 Vp-p (0.2 Vrms): recommended level

0.2 Vp-p–0.5 Vp-p (0.1 Vrms–0.25 Vrms): acceptable level

2. When NOT using a measuring device.

q Connect the IC-207H to a TNC.
w Enter a test mode (“CAL”, etc.) on the TNC, then transmit

some test data.

e When the transceiver fails to transmit the test data or

transmits sporadically (TX indicator doesn’t appear or

■ Fuse replacement

If the fuse blows or the transceiver stops functioning, find the
source of the problem if possible, and replace the damaged
fuse with a new, rated one (FGB 20 A) as shown in the dia­gram below.

■ Partial resetting

If you want to initialize the operating conditions without clear­ing the memory contents, etc., a partial reset function is avail­able for the transceiver.

While pushing [V/MHz], turn power ON to partially reset the
transceiver.

➧ Initialized settings: VFO frequency, SET mode settings.
➧ Retained settings: Memory channels, call channels, offset

freq. in memory/call, DTMF memory, ini­tial SET mode settings.

■ Resetting the CPU

The function display may occasionally display erroneous in­formation, (e.g. when first applying power). This may be
caused externally by static electricity, or by other factors.

If this problem occurs, turn power OFF. After waiting a few
seconds, turn power ON again. If the problem persists, per­form the following procedure.

Partial resetting is alternatively available. See previous sec­tion for details.

➀ Push [PWR] to turn power OFF.
➁ While pushing [SET] and [S.MW], turn power ON.

•“CLEAr” appears and the transceiver is reset.

CAUTION: Resetting the transceiver CLEARS all

memory information, and initializes all values in the trans-
