          More features includes

          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.

          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.

          Non GPS type         12 hours (approx.) 12.5 hours(approx.)

          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)
          -Stun, kill and revive
          -Radio check
          -Remote monitor
