Compliance with the ATEX Directive is now a legal requirement in all European member states. Only portable radios type approved to the ATEX Directive are regarded as intrinsically safe in EU/EFTA countries. This does not apply to mobile offshore units, and shipping vessels over 500 gross tons as they are covered by IMO convention.

The ATEX versions of the Icom IC-F51 (VHF) and Icom IC-F61 (UHF), conforms to the 94/9/EC ATEX Directive. The IC-F51 series is a waterproof PMR transceiver whose construction is equivalent to IPX7* which is the same rating as our marine handheld models. In addition, built-in signalling capabilities and UT-110 compatible voice scrambler function eliminate the need for an optional logic board. The IC-F51 series meets the requirements for a tough, waterproof communications tool for use in hazardous areas such as oil rigs, areas where flammable gases or liquids are used, and other potentially explosive environments.

     * Equivalent to IPX7 of the corresponding International Standard
       IEC 60529(2001). 1m depth for 30 minutes

This ATEX approved IC-F51/F61 transceiver offers safety approved 2-way communication preventing explosion and fire hazard in specified hazardous areas.

• Waterproof construction - The IC-F51 series has waterproof construction which is equivalent to IPX7. The IC-F51 series can withstand submersion in 1m depth of water for up to 30 minutes.


• Tough and compact body - The aluminium die-cast chassis combined with a polycarbonate casing is designed to last. Its compact dimensions of 97 (H) x 56 (W) x 36 (D) mm allow the IC-F51 series to fit comfortably in your palm or shirt pocket.


• Standard Lithium-Ion battery pack - The IC-F51 series comes with a standard 1700mAh Lithium-Ion battery pack, BP-227AX that provides stable output power and a practical 13 hours* of operating time. Lithium-ion batteries allow flexible charging** and have almost no memory effect.
  
       *  Typical operation; Tx:Rx:Stand-by duty cycle=5:5:90
       ** Please note that ATEX radios should not be charged in
           hazardous environments.


• Alphanumeric LCD - The IC-F51 features an 8-character 14 segment alphanumeric LCD. An automatic LCD backlight is standard, ideal for night time operation.


• Built-in signaling - The IC-F51 series has 2-Tone, 5-Tone, CTCSS and DTCS signalling capabilities for group communication or selective calling as standard.


• Built-in rolling type voice scrambler* - The IC-F51 series has a built-in voice scrambler. The scrambling system is fully compatible with the UT-110 voice scrambler unit, which uses 1020 codes (255 codes x 4 groups.). In addition, an inversion type voice scrambler is available in all versions.
  
       *  ATEX version has a built-in UT-110 compatible
          voice scrambler.


• Programmable functions - Up to 7 programmable buttons, [P0]–[P3], [▲], [▼],and [Red button] can be assigned additional functions to meet a variety of requirements. In addition, there is a space for function assign stickers below these buttons.

• 12.5kHz channel step (VHF only)Wide/middle/narrow channel spacing
• Built-in commander (same as IC-F31G series and IC-F510 series)
• BIIS 1200 built-in SMA type ANT connector
• Up to 128 memory channels/8 memory banks
• MIL spec tested to MIL-STD F.
