quency Electromagnetic Fields (OET Bulletin 65).

RWARNING! NEVER connect the transceiver to an AC out-

let. 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 will damage the transceiver.

NEVER connect the transceiver to a power source using reverse

polarity. This will damage 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

may be damaged.

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

transceiver may be damaged.

NEVER operate or touch the transceiver with wet hands. This may

result in an electric shock or damage the transceiver.

NEVER place the transceiver where normal operation of the vehi-

cle 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 contain-

ing a transmitter.

During mobile operation, DO NOT operate the transceiver with-

out running the vehicle’s engine. When the transceiver’s power is ON

and your vehicle’s engine is OFF, the vehicle’s battery will soon be-

come exhausted.

AVOID using or placing the transceiver in direct sunlight or in

areas with temperatures below –10°C or above +60°C.

BE CAREFUL! The transceiver will become hot when operat-

ing it continuously for long periods.

AVOID setting the transceiver in a place without adequate venti-

lation. Heat dissipation may be affected, and the transceiver may be

damaged.

AVOID the use of chemical agents such as benzine or alcohol

when cleaning, as they can damage the transceiver’s surfaces.

USE Icom microphones only (supplied or optional). Other manu-

facturer’s microphones have different pin assignments and may dam-

age the transceiver if attached.

For U.S.A. only

CAUTION: Changes or modiﬁcations to this device, not ex-

pressly approved by Icom Inc., could void your authority to

operate this device under FCC regulations.

■Your ﬁrst contact

Now that you have your IC-208H installed in your car or

shack, you are probably excited to get on the air. We would

like to take you through a few basic operation steps to make

your ﬁrst “On The Air” an enjoyable experience.

1. Turning ON the transceiver

Before powering up your IC-208H, you may want to make

sure the audio volume and squelch level controls are set in

9–10 o’clock positions.

Although you have purchased a brand new transceiver, some

settings may be changed from the factory defaults because

of the QC process. Resetting the CPU is necessary to start

from factory default.

➥While pushing both [SET•LOCK] and [S.MW•MW], push

[PWR] for 1 sec. to reset the CPU.

2. Selecting the operating frequency band

The IC-208H has 2 m and 70 cm bands.

➥Push [BAND] to select the desired frequency band.

Using the HM-133

You can select the main band from the HM-133.

ANTENNA INFORMATION

For radio communications, the antenna is of critical impor-

tance, to maximize your output power and receiver sensi-

tivity. The transceiver accepts a 50 Ωantenna and less

than 1:1.5 of Voltage Standing Wave Ratio (VSWR). High

SWR values not only may damage the transceiver but also

lead to TVI or BCI problems.

■Squelch attenuator

The transceiver has an RF attenuator related to the squelch

level setting. Approx. 10 dB attenuation is obtained at maxi-

mum setting.

The squelch attenuator allows you to set a minimum signal

level needed to open the squelch. The attenuator function can

be deactivated in initial set mode.

➥Rotate [SQL] clockwise past the 12 o’clock position to ac-

tivate the squelch attenuator.

•Attenuation level can be adjusted up to 10 dB (approx.) between

12 o’clock and fully clockwise position.

•When setting the squelch from the microphone, a level greater

than ‘19’activates the squelch attenuator.

IMPORTANT! (for 55/50 W transmission):

The IC-208H is equipped with protection circuit to protect

the power amplifier circuit from high SWR (Standing Wave

Ratio) and temperature. When a high SWR antenna or no

antenna is connected, or when the transceiver temperature

becomes extremely high, the transceiver reduces transmit

output power to 15 W (approx.) automatically.

REPEATER OPERATION

New2001

Repeaters allow you to extend the operational range of your

radio because a repeater has much higher output power than

the typical transceiver.

Normally, a repeater has independent frequencies for each

receiver and transmitter.

A subaudible tone may also be required to access a repeater

Reference amateur radio hand books and local ham maga-

zines for details of local repeaters such as repeater input/out-

put frequencies and locations.

•Repeater operation ﬂow chart

•The IC-208H USA version has the auto repeater function. Thus the

steps 3 and 4 may not be necessary, depending on the setting.

•Repeater settings can be stored into a memory channel.

Step 3:

Set the duplex (shifting) direction (– duplex or +duplex).

- Set the offset frequency (shifting value), if required.

Step 4:

Set the subaudible tone (repeater tone) encoder function ON.

- Set the subaudible tone frequency, if required.

Step 1:

DAdjusting the transmit signal output from

the TNC

When setting data transmission speed to 9600 bps, the data

signal coming from the TNC is applied exclusively to the in-

ternal limiter circuitry to automatically maintain band width.

NEVER apply data levels from the TNC of over 0.6 V p-p, oth-

erwise 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 V p-p (0.2 V rms) : recommended level

0.2 V p-p–0.5 V p-p (0.1–0.25 V rms) : acceptable level

2. When NOT using a measuring device.

qConnect the transceiver to a TNC.

wEnter a test mode (“CAL”, etc.) on the TNC, then trans-

mit some test data.

eWhen the transceiver fails to transmit the test data or

transmits sporadically (TX indicator doesn’t appear or

ﬂashes):

- Decrease the TNC output level until the transmit indi-

cator lights continuously.

When transmission is not successful even though the

TX indicator lights continuously:

- Increase the TNC output level.
