FOREWORD
Thank you for purchase of this fine Icom product. We under-
stand you have a choice of many different radios in the mar-
ket place. Many hours of research and development went into
the design of your IC-91A/91AD, following Icom’s philosophy
of “technology first.”
The IC-91A/91AD
VHF / UHF FM TRANSCEIVER is designed with
Icom’s superior technology and craftsmanship combining tra-
ditional analog technologies with the new digital D-STAR
technologies for a balanced packaged.
With proper care, this product should provide you with years
of trouble-free operation. We want to take a couple of mo-
ments of your time to thank you for making your IC-91A/91AD
your radio of choice, and hope you agree with Icom’s philos-
ophy of “technology first.”

RWARNING RF EXPOSURE! This device emits
Radio Frequency (RF) energy. Caution should be observed
when operating this device. If you have any questions re-
garding RF exposure and safety standards please refer to the
Federal Communications Commission Office of Engineering
and Technology’s report on Evaluating Compliance with FCC
Guidelines for Human Radio Frequency Electromagnetic
Fields (OET Bulletin 65)
RWARNING! NEVERhold the transceiver so that the
antenna is very close to, or touching exposed parts of the
body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm (2
to 4 inches) away from the lips and the transceiver is vertical.
RWARNING! NEVER operate the transceiver with a
earphone, headphones or other audio accessories at high
volume levels. Hearing experts advise against continuous
high volume operation. If you experience a ringing in your
ears, reduce the volume level or discontinue use.
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 ruin the transceiver.
NEVER connect the transceiver to a power source using
reverse polarity. This will ruin the transceiver.
NEVERexpose 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 trans-
ceiver.
DO NOT operate the transceiver near unshielded electri-
cal blasting caps or in an explosive atmosphere.
DO NOTpush the PTT when not actually desiring to transmit.
BE CAREFUL! The transceiver will become hot when op-
erating it continuously for long periods.
AVOIDusing or placing the transceiver in direct sunlight or
in areas with temperatures below –20°C (–4˚F) or above
+60°C (+140˚F).
Place the unit in a secure place to avoid inadvertent use by
children.
AVOID the use of chemical agents such as benzine or al-
cohol when cleaning, as they can damage the transceiver’s
surfaces.
For U.S.A. only
CAUTION!: Changes or modifications to this device, not
expressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.
