Intrinsically Safe

IC-F3161T/S, IC-F4161T/S
IS: Class I,II,II/Div 1/Groups CDEFG/T3C Ta = 40°C
NI: Class I/Div 2/Groups ABCD/T3C Ta = 40°C

Special condition for use
Must be used with the BP-232FM battery. The HM-169IS, VS-1SC, HS-94 and HS-97 are approved as instrinsically safe options. Any other options, except the antenna, belt clip and belt hanger, cannot be used in explosive atmosphere areas.

Never change the BP-232FM (with/without the transceiver) in an explosive atmosphere. The optional battery chargers are not approved as intrinsically safe.

Supplied Accessories

  • Antenna (UHF or VHF)
  • Battery pack, BP-232H or BP232N FM (depending on version)
  • Belt clip, MB-94N
