Description
VHF and UHF IDAS Digital Mobile Radios for Fleet Communications
The Icom F5400D and F6400D are mobile two-way radios for vehicle and fixed-station communications. This listing offers VHF and UHF configurations, including a VHF railroad-firmware option and a UHF version without Bluetooth. Select the frequency range and configuration required by your system before ordering.
The series supports NXDN digital and analog FM operation, with a color LCD, programmable controls and active noise cancellation. Network compatibility depends on the radio version, programming, signaling and any required feature upgrades; the radio does not guarantee coverage across every site or route.

System Compatibility and Optional Features
Match the band, frequencies, channel settings, digital mode and signaling to the intended system. NXDN Type-D single/multi-site trunking requires the appropriate ISL-UGMTR upgrade. Multi-site operation also depends on the supporting network and configuration.
GPS requires the optional UX-241 antenna. Voice recording requires a separate microSD card; a fixed 500-hour recording duration is not established by the attached brochure. Recording capacity depends on the supported card and settings.
Encryption and over-the-air functions have separate prerequisites. The brochure specifies UT-134 and ISL-AKAES for AES, CS-OTPM1 for OTAP management and CS-OTAR1 for OTAR management. Confirm the hardware, licenses, software and system support needed for the intended workflow rather than assuming these are included.

Frequently Asked Questions
What is the difference between F5400D and F6400D?
F5400D is the VHF model, with up to 50 W output. F6400D is the UHF model, with up to 45 W output. Select the exact sub-band; these are not dual-band radios.
What does the railroad-firmware option include?
F5400D-RR is listed with railroad firmware. Confirm the required firmware release, channel plan and programming before ordering. The option name alone does not establish compliance with every railroad system or operating requirement.
Do all four configurations have Bluetooth?
No. The F6400D-56 380–470 MHz option is listed without Bluetooth. The other three listed configurations include Bluetooth. Third-party audio compatibility must still be checked.
Is the UHF upper range 512 or 520 MHz?
The F6400D-71 option in this listing is 450–512 MHz. The international family brochure also describes a 450–520 MHz version. Confirm the exact supplied variant instead of assuming the ranges are interchangeable.
Does GPS work without an additional antenna?
The brochure specifies an optional UX-241 GPS antenna for the built-in GPS receiver. The antenna is not specified as part of this package.
Is voice recording ready without a memory card?
No. Recording and playback use a separately supplied microSD card. The brochure does not substantiate a fixed 500-hour recording claim for the package.
Are NXDN trunking and AES encryption included as standard?
Do not assume so. NXDN Type-D trunking requires the appropriate upgrade key. AES requires the specified encryption unit and activation key. Confirm the exact configured feature set before purchase.
What do I need to program the radio, or can Atlantic Radio program it for me?
For self-programming, use the Icom OPC2363 programming cable together with the correct Icom Customer Programming Software (CPS); the series brochure specifies CS-F3400D for F5400D/F6400D radios. Confirm the software version, computer connection requirements and compatibility with the selected configuration, particularly railroad firmware. The cable and software are sold separately. If you prefer professional configuration instead, choose Atlantic Radio Programming Services and confirm the appropriate service for your channel plan and analog or NXDN conventional system. Specialized railroad or trunked-system work requires prior confirmation and should not be assumed to be covered by the standard service.
Is the IP55 radio submersible?
IP55 denotes dust protection and water-jet resistance, not a submersion rating.
What warranty is listed?
3 years on the radio and 1 year on the included accessories.
