The ATEX versions of the IC-F51 and F61, 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.

Approved classes

The approved rating is II2G EEx ib IIA T3.

Special conditions for use:
• Must be used with BP-227AX
Approved accessories:
• Speaker-microphone HM-138

Please ensure the IC-F51/F61 ATEX rating is acceptable for the intended place of use.

These ATEX models have all the same functions and features as non-ATEX versions including;

Waterproof construction

Tough and compact body
The aluminium die-cast chassis combined with a polycarbonate casing is designed to last. Its compact dimensions of 56 (W) x 97 (H) 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.
