IC-A120 Mobile Unit

Icom’s A120 air band mobile introduces two new features: Active Noise Cancelling (ANC) and Bluetooth® capabilities. The newly added built-in ANC reduces background noise and is effective in extremely noisy airport environments. The automatic noise limiter (ANL) reduces pulse-type noise such as engine ignition. Insert the optional UT-133A Bluetooth® unit and connect a third-party wireless Bluetooth® headset.

This unit is great for any mobile application and it’s available in a base station. Both are built to mil spec for superb reliability!

ON-hook Scan and Dualwatch Functions

The ON-Hook scan function automatically starts scanning when the hand microphone is hooked on the microphone hanger. When you take the microphone OFF hook, the scanning stops at the priority channel or displayed channel. The Dualwatch function checks the priority and operating channels alternatively.

Side Tone Function

When using a third-party headset with the optional OPC-871A headset adapter, the side tone function allows you to monitor your own transmitted voice via the connected headset. Even when using a hand microphone, your voice can be monitored from the headset.

Additional Features

• Compatible with both 12V and 24V systems

• Dualwatch and priority scan functions

• Power on password protection

• CI-V commands for external control

• Connect with other radio devices with the VE-PG3 RoIP gateway

• Dot-matrix LCD display is easy to read with crisp, clear text (displays alphanumeric characters and icons)
• Memory channels and other radio settings can programmed from the front panel (customizing functions can be restricted as needed, depending on the radio settings); this unit provides 200 memory channels with 12-character channel names and 8.33 kHz and 25 kHz channel spacing
• Built-in Active Noise Canceling (ANC) reduces background noise in the received and transmitted signals; the automatic noise limiter (ANL) reduces pulse-type noise such as engine ignition (ANL and ANC functions cannot be used at the same time)
• IP54 dust-protection and water resistant construction allows the IC-A120 to be used in open-air vehicles
• ON-Hook scan function automatically starts scanning when the hand microphone is hooked on the microphone hanger; the ON-Hook dualwatch feature checks the priority and operating channels alternatively while ON-Hook; when the microphone is taken OFF hook, scanning stops at the priority channel or the displayed channel
• Provides optional Bluetooth headset connectivity when the UT-133 Bluetooth unit is added; this allows a third-party wireless Bluetooth headsets to be used with the IC-A120 (when using an optional VS-3 Bluetooth headset the side tone function becomes available)
• Third-party headsets can be used with the optional OPC-871A headset adapter; when configured this way, the user can use the side tone function to monitor his or her own transmitted voice via the connected headset—even when using a hand microphone
• Optional HM-217 speaker-microphone allows the user to listen to received audio through the HM-217’s built in speaker; the speaker-microphone features up/down buttons as well as two programmable P1/P2 buttons that serve as a shortcut for activating frequently used functions
• Compatible with 12- and 24- volt systems
• 36W (PEP) RF output power
• Dualwatch and priority scan functions
• Power on password protection
• PC programming capability
• CI-V Commands for external control
• VE-PG3 RoIP gateway for interconnect with other radio devices
• Accessories include hand microphone (HM-216), DC power cable, microphone hanger kit, mounting bracket kit, and fuses
