Slim, Lightweight, High Performance

The IC-M25 has the slim (depth:30.5 mm; 1.2 in) and light (218 g; 7.7 oz) body. It also delivers uncompromised performance that will exceed expectations.

Large LCD, Simple User Interface

The IC-M25’s LCD is 30% larger than its predecessor, the IC-M24 and shows clearly large channel numbers and status icons. The buttons on the front panel are well laid out and provide simple and straightforward operation.

USB Charging (Micro-B USB type)

A USB connector (Micro-B type) is used to charge the IC-M25. Cigarette lighter cables or mobile batteries for charging smartphones or other devices can be used with the IC-M25*.

* The IC-M25 accepts 5 V/1 A (Max.) input. Use of third-party products is not guaranteed.

Float'n Flash

The IC-M25 floats and lets you know where it is with the flashing red LED light and LCD/key backlight.

11 Hours of Battery Life

The built-in 1500 mAh lithium-ion battery allows 11 hours (approx.) of long operation*.

* Typical operation with Tx (Hi): Rx: standby=5:5:90

Optional Speaker-Microphone, HM-213

The optional waterproof speaker-microphone, HM-213, provides commercial-grade convenience while mounting the radio around the waist. The radio floats even when the HM-213 is attached.

550 mW Audio Output

The IC-M25 provides a powerful 550 mW (typical) audio output and the received voice can be heard loud and clear.
