5 W Output Power Also in UHF, 1500 mW Audio

VHF IC-F3003
UHF IC-F4003

Simple operation for instant communication

The IC-F3003 series is so easy to use there’s no special training required. The few knobs and buttons are generously sized for easy operation and are designed to provide non-slip, positive action – even while wearing gloves.

Easy to hear in noisy areas

The radio provides 1500 mW* loud and clear audio with Icom custom high power handling capacity speaker. Clear communication is available even in noisy environments.

* Typical with internal speaker

Longer operating time

A new high efficiency FET of the IC-F3003 series reduces consumption current and provides up to 22 hours* of operating time with the BP-298, 2250 mAh (typical) supplied battery pack.
*Tx:Rx:Standby=5:5:90. Power save function ON.

Weather resistant, dust protection, military rugged

While the radio is a compact unit with a height of only 111 mm, the radio is tested to dust protection and water resistant equivalent to IP54 and 11 categories of MILSTD- 810 environmental tests. In short, the IC-F3003 series is built rugged!

Internal VOX capability for hands-free operation

The radio has the internal VOX capability for hands-free operation. Optional compatible headset with plug adapter cable OPC-2004LA can be used with the radio. Also, the VOX gain and VOX delay time are adjustable.

Selective calling, quiet stand-by and more

2-Tone and 5-Tone signaling gives you selective calling, quiet stand-by and other convenient functions with programming. The radio “stun” function disables a radio over the air and the “revive” function restores the stunned radio.

Scan features

The priority scan allows you to monitor one or two priority channels while scanning other non-priority channels. The TX channel and talk back functions allow you to make a quick response while scanning.
