MultiTrunk now available

MultiTrunkIDAS multi-site operation has now expanded to trunking! MultiTrunk opens the possibility of building a regional or multi-campus system of trunking repeaters.

FM instrinsically safeIntrinsically safe version available

The Intrinsically safe version is approved by the FM Approvals. For use in workplaces where combustible substances or environments exist. See new brochure for more details.

Basic LTR®/conventional mode operation

Both LTR® trunking and conventional channels are programmable on a radio. Group, selective (DTMF), and phone call are available in LTR® mode.

PassPort™ Option

IDAS mobile and portable subscribers can support both the latest versions of PassPort™ or is backward compatible to earlier versions. Icom PassPort is a reliable alternative to add to your PassPort Fleet.

IP55 dust-protection and water jet resistance

The IC-F3161/D series meets IP55 requirements for dust-protection and water jet resistance. Its durable construction is backed up by the aluminum die-cast chassis and polycarbonate casing, allowing reliable operation under harsh weather and environmental conditions.

Lithium-Ion battery pack

The supplied 2000mAh Li-Ion battery pack, BP-232N, provides 14 hours* of operating time. The optional battery case BP-240 provides a convenient back up and great reassurance in an emergency.
*Typical operation Tx:Rx:Stand-by=5:5:90, power save on

Most popular signalings built-in

The 2-Tone, 5-Tone, CTCSS, DTCS and MDC signaling capabilities are built-in for group communication or selective calling. The radio can decode ten 2-Tone codes or eight 5-Tone codes on a channel. When a matched tone is received, the following actions are programmable for each code.

  • Beep sound
  • Bell icon
  • Answer back call
  • Auto TX
  • Radio stun/kill/revive
  • Scan

MDC 1200 Compatible

The following selective calling and ANI features are available with the built-in MDC signaling.

  • PTT ID
  • SelCall
  • Radio check
  • Radio stun/revive
  • 500 Aliases
  • Status message/request
  • Call alert
  • Emergency, emergency mic monitoring

Voting mode scanning

The voting mode scanning detects the signal strength level of repeater stations and automatically selects the strongest station, useful for roaming between 2 or more repeater sites. Once you program the voting mode to a memory zone, you can easily start voting mode operation by changing the zone setting.

Full dot-matrix LCDFull dot-matrix LCD

Using a large full dot-matrix LCD (32 18 mm), the IC-F3161/D series shows upper and lower case characters clearly. The display setting is selectable from 1 line, 12 characters or 2 lines 24 characters via programming. The bottom row shows assigned functions to the [P0] to [P3] buttons.

Enhanced audio

The IC-F3161/D series employs a BTL amplifier that increases the audio output and the built-in audio compander provides clear, low noise communications.

Lone worker function

When the radio is not operated for a preset period, a beep sounds and a button push is required. If no button is pushed within that preset time, an emergency signal automatically transmits and alerts your co-worker or dispatcher to any potential trouble.

Built-in inversion-type voice scrambler

The built-in inversion type voice scrambler* provides secure conversation as standard. When a more secure system is required, the 32 code non-rolling-type voice scrambler UT-109R and 1020 code rolling type UT-110R are available as an option.
*Inversion type voice scrambler is not compatible with UT-109/UT-110 voice scrambler.
