IP67 Dust-tight & Waterproof Protection

The IC-F3261D series provides rugged protection against dust and water that is equivalent to IP67. The radio can withstand 1m depth of water for 30 minutes.

Man Down and Lone Worker Functions for Emergency Call

The man down function* automatically sends an emergency signal when the transceiver is left in a horizontal position. The lone worker function also can transmit an emergency signal when the radio is not operated for a preset period. These emergency signals can be sent with GPS position data* to alert your co-workers or dispatcher to any potential trouble.

* Depending on the version.

800mW (typ.) Audio Output Power

The built-in BTL amplifier doubles the audio output power and the large 40mm speaker delivers loud 800mW (typ.) audio to receive all calls under noisy environments.

Built-in GPS Receiver*

Your current position data can be attached to a voice or data (SDM, status or emergency signal) transmission and can be sent to dispatch stations*.

*Depending on the version.
*To show the received position data, an external PC application is required.

14-pin Accessory Connector

The new 14-pin accessory connector enhances audio output capabilities with the built-in BTL amplifier. The optional HM-184 speaker - microphone provides a 1000mW (typ.) audio output for loud and clear communication.

Large Full Dot-Matrix LCD

Using a large full dot-matrix LCD (32 × 18mm), the IC-F3261D series shows two lines of easy to read text messages. The bottom row shows assigned functions to the [P0] to [P3] buttons.

IDAS™ Features

The IC-F3261D series provides NXDN™ CAI-based IDAS digital mode operation. It is also compatible with NXDN™ Type-D multisite trunking. The following IDAS features are programmable.

  • Individual/group call
  • Individual ID and talkgroup ID memories
  • Status message
  • SDM (Short Data Message)
  • GPS
  • Stun, kill and revive
  • Radio check
  • Remote monitor
  • Call alert
  • Call log
  • Emergency
  • Digital voice scrambler
  • Block decode
  • RAN (Radio Access Number)

Built-in 2-Tone and 5-Tone*

2-Tone and 5-Tone signalings give you selective calling, quiet stand-by and other convenient functions. The radio stun and kill functions disable a radio over the air and the revive function restores the stunned radio.

* Analog mode only

MDC 1200 Compatible*

The built-in MDC signaling provides the following selective calling and ANI features.

  • PTT ID
  • SelCall
  • Radio check
  • Radio stun/revive
  • 500 aliases
  • Status message/request
  • Call alert
  • Emergency, emergency mic monitoring

* Analog mode only

Scan Features

The IC-F3261D series can detect both analog and IDAS conventional signals and automatically selects the transmission mode to reply to the received call.

Built-in Voice Scrambler

The built-in inversion voice scrambler* provides secure conversation in analog mode. When using IDAS digital mode, the digital voice scrambler provides a 15-bit key (about 32,000 codes) as standard.

* Inversion voice scrambler is not compatible with UT-109R/UT-110R voice scrambler.
