FOREWORD
READ ALL INSTRUCTIONS carefully and completely before
using the transceiver.
SAVE THIS INSTRUCTION MANUAL— This instruction
manual contains important operating instructions for the IC-F51
vhf transceiver and IC-F61 uhf transceiver.
EXPLICIT DEFINITIONS
WORD DEFINITION
RWARNING Personal injury, fire hazard or electric shock
may occur.
NOTE If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
CAUTION Equipment damage may occur.
OPERATING NOTES
• When transmitting with a portable radio, hold the radio in a ver-
tical position with its microphone 5 to 10 centimeters away from
your mouth. Keep the antenna at least 2.5 centimeters from your
head and body.
• If you wear a portable two-way radio on your body, ensure that
the antenna is at least 2.5 centimeters from your body when
transmitting.

ii
PRECAUTIONS
RWARNING! NEVER hold the transceiver so that the an-
tenna is very close to, or touching exposed parts of the body, espe-
cially the face or eyes, while transmitting. The transceiver will per-
form best if the microphone is 5 to 10 cm away from the lips and
the transceiver is vertical.
RWARNING! NEVER operate the transceiver with a headset
or other audio accessories at high volume levels.
CAUTION! NEVER short the terminals of the battery pack.
NEVER connect the transceiver to a power source other than the
BP-227AX. Such a connection will ruin the transceiver.
NEVER use non-Icom battery packs/chargers to prevent the loss
of the transceiver’s good performance and warranty.
DO NOT push the PTT when not actually desiring to transmit.
DO NOT use or place the transceiver in direct sunlight or in areas
with temperatures below –20°C or above +55°C.
The basic operations, transmission and reception of the trans-
ceiver, are guaranteed within the specified operating temperature
range (depending on version). However, the LCD display may be
operate correctly, or show an indication in the case of long hours of
operation, or after being placed in extremely cold areas.
DO NOT modify the transceiver for any reason.
MAKE SURE the flexible antenna and battery pack are securely
attached to the transceiver, and that the antenna and battery pack
are dry before attachment. Exposing the inside of the transceiver to
water will result in serious damage to the transceiver.
Icom optional equipment is designed for optimal performance when
used with this transceiver. We are not responsible for the trans-
ceiver being damaged or any accident caused when using non-
Icom optional equipment.

INTRINSIC SAFETY
Versions of the IC-F51/F61 which display the “EX” mark-
ing on the serial number seal.
The approval rating for these models is II2G Ex ib IIA T3.
WARNING! NEVER charge the BP-227AX (with/without the trans-
ceiver) in an explosive atmosphere. The optional battery chargers are
not approved as Intrinsically Safe.
When the transceiver is used in a hazardous area, the BP-227AX
MUST be attached, either the jack cover or HM-138 MUST be at-
tached to the speaker-microphone connector.
KEEP the transceiver and the BP-227AX clean to avoid any risk of ig-
nition due to the build-up of electrostatic charges.
Repair of Icom radios should only be carried out by authorized Icom
distributors. In particular, repair of ATEX approved radios can ONLY
be done by Icom to maintain the intrinsically safe rating. NEVER at-
tempt to repair an ATEX approved radio. Only Icom has the repair ex-
pertise and procedures to maintain the ATEX approval. Contact your
Icom distributor or authorised dealer for details.
The ATEX standard is described on the 94/9/EC sticker (Ex Mark-
ing) and BP-227AX as below.
The following illustrations are show for the IC-F51/F61.

■Accessory attachments
DFlexible antenna
Connect the supplied flexible antenna
to the antenna connector.
CAUTION!
• NEVER HOLD by the antenna when
carrying the transceiver.
• Transmitting without an antenna
may damage the transceiver.
ïJack cover
Attach the jack cover when the optional speaker-microphone is not
used.
When the transceiver is used in a hazardous areas, either the jack
cover or HM-138 must be attached to the connector. Failure to do
this will make the radio ATEX non-compliant and may result in an
accident during use in hazardous areas.
To attach the jack cover:
qInsert the jack cover into the
[SP MIC] connector.
wTighten the screw.
To detach the jack cover:
qUnscrew the screw with a
phillips screwdriver.
wDetach the jack cover for the
speaker-microphone con-
nection.

ïBattery pack
To attach the battery pack:
Slide the battery pack on the back of the transceiver in the direction
of the arrow (q), then lock it with the battery release button.
• Slide the battery pack until the battery release button makes a ‘click’
sound.
To release the battery pack:
Push the battery release button in the direction of the arrow (w) as
shown below. The battery pack is then released.
NEVER release or attach the battery pack when the transceiver
is wet or soiled. This may result in water or dust getting into the
transceiver/battery pack and may damage the transceiver.

3CONVENTIONAL OPERATION
■Call procedure
When your system employs tone signalling (excluding CTCSS and
DTCS), the call procedure may be necessary prior to voice trans-
mission. The tone signalling employed may be a selective calling
system which allows you to call specific station(s) only and prevent
unwanted stations from contacting you.
qSelect the desired TX code channel or 5-tone code according to
your System Operator’s instructions.
• This may not be necessary depending on programming.
• Refer to pgs. 16, 17 for selection.
wPush the call switch (assigned to one of the dealer programma-
ble switches: [P0], [P1], [P2], [P3], [Red], [ ] and [ ]).
eAfter transmitting a 5-tone code, the remainder of your commu-
nication can be carried out in the normal fashion.
