Icom IC-455 UHF 477 MHz CB Transceiver 12V-24V DC Autosensing

(IC-455)

5 Watt RF Output Power

5 Watts (High) and 1 Watt (Low) selectable output power.

Seven-Colour Backlight LCD

The colour of the LCD Screen can be changed to reflect the operating status. Different colours can be assigned to channels, and colours can be set to indicate when scanning or transmitting.

Noise Reduction, Audio Equalizer & Voice Changer

The Noise Reduction reduces background noise from both transmit and receive audio.

Voice Recorder & Instant Play Back

Can record up to 10 messages of 30 seconds each, for a total of 5 minutes.

Supports Both 12 V/24 V DC Power Sources

Accepts a 12/24 V DC power source and it is suitable for most types of cars and trucks.

Dynamic Group Scan for Keeping Group Communication

Using a CTCSS or DTCS tone, this function finds an open channel for group communicaton.

Loud Speaker-Microphone with Auto Volume Control

The microphone monitors ambient noise levels and automatically adjusts the audio level.
