FOREWORD
Thank you for purchasing this Icom product. The IC-T90A
MULTIBAND TRANSCEIVER is designed and built with
Icom’s superior technology and craftsmanship. With proper
care, this product should provide you with years of troublefree operation.
The IC-T90A is a tri-band, 6 m, 2 m (140 MHz), 440 MHz FM
transceiver that offers a wide-band AM, FM and WFM scanning receiver. Not only you can hear your favorite TV programs with the pre-programmed TV memories, but also you
can listen to short wave, AM and FM broadcast radio stations,
police, fire, military, aircraft, various amateur bands and more.
New DMS(Dynamic Memory Scan) bank scanning provides
555 alphanumeric memory channels, including 50 band
edges, with a maximum of 18 banks or 100 channels per
bank, you can pick and choose any desired channel for scanning from the 500 memories.
The supplied BP-217 LITHIUM-ION BATTERY PACK provides full
5 W outputs. Along with the energy conserving settings the
BP-217 provides up to 5 to 6 hours of operating time.
The supplied MB-83 swivel type belt clip performs quick draw
action for attach/detach the transceiver from the belt clip.
And newly designed antenna also provides a stable signal
strength.
We want to thank you for making your IC-T90A your radio of

Engineering and Technology’s report on Evaluating
Compliance with FCC Guidelines for Human Radio frequency
Electromagnetic Fields (OET Bulletin 65)
NEVER connect the transceiver to a power source that is
WARNING! NEVER hold 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 1 to 2 in (2
to 5 cm) away from the lips and the transceiver is vertical.
AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below +14°F (–10°C) or above
+140°F (+60°C).
WARNING! NEVER operate the transceiver with a
headset 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.
NEVER CONNECT a power supply more than
11.5 V DC to the DC jack. The supply voltage must be
between 5.5 V and 11.5 V to prevent damaging the transceiver.
NEVER connect the transceiver to an AC outlet . Such a
connection will damage the transceiver.
iii
DC fused at more than 5 A. Accidental reverse connection will
be protected by this fuse, but higher fuse values will not give
proper protection against such accidents and the transceiver
will be ruined.
DO NOT operate the transceiver near unshielded electrical
blasting caps or in an explosive atmosphere.
The use of non-Icom battery packs/chargers may impair
transceiver performance and invalidate the warranty.
Even when the transceiver power is OFF, a slight current still
flows in the circuits. Remove the battery pack or case from
the transceiver when not using it for a long time. Otherwise,
the battery pack or installed batteries will become exhausted.
For U.S.A. only

NEVER short terminals of the battery pack. Also, current may
flow into nearby metal objects so be careful when placing battery packs in handbags, etc.
If your battery pack seems to have no capacity even after
being charged, completely discharge it by leaving the power
ON overnight. Then, fully charge the battery pack again. If the
battery pack still does not retain a charge (or very little), a
new battery pack must be purchased.
Use Icom battery packs, chargers and cables only. The use of
non-Icom products may impair transceiver performance and
invalidate the warranty.
Even when the transceiver power OFF, a slight current still
flows in the circuits. Remove the battery pack or case from
the transceiver when not using it for a long time. Otherwise,
the battery pack or installed batteries will become exhausted.

OFF after 1, 3, 5 or 10 min. of continuous transmission. This
timer can be cancelled (default).
The transceiver can be set to automatically turn OFF after a
specified period with beep in which no switch is pushed.
Approx. 10 sec. before the time-out timer is activated, the
transceiver emits a beep tone as a warning.
This can be selected in expanded set mode 2. (p. 65)
■ PTT lock
To prevent accidental transmission, etc., the transceiver has a
PTT lock function.
This can be selected in expanded set mode 1. (p. 64)
120 min., 90 min., 60 min., 30 min. and OFF can be specified. The specified period is retained even when the transceiver is turned OFF by the auto power-off function. To cancel
the function, select “OFF” in the auto power-off item in set
mode.
This can be selected in set mode. (p. 59)
■ Auto power ON
The transceiver can be set to automatically turn ON after a
specified period. The timer can be selected within 30 min. to
24 hrs. in 30 min. steps.
This can be selected in expanded set mode 1. (p. 63)
When operating with battery pack or case and the battery
is exhausted, auto power-on does not function.
