Built-in 2-Tone and 5-Tone (Analog Mode)

2-Tone and 5-tone signalings give you selective calling, quiet stand-by and other convenient functions with programming. The stun/kill functions disable a radio over the air and the revive function restores the stunned radio.

Scan Features

The priority scan allows you to monitor one or two channels while scanning other non-priority channels. The transmit channel and talk back functions allow you to make a quick response while scanning.

MDC 1200 Compatible (Analog Mode)

The following MDC features are available with the built-in MDC signaling.

• PTT ID
• Radio check (RX)
• Emergency (No ACK)
• Stun/Revive (RX)
• 500 alias table (Max.)

Lone Worker Function

When the radio is not operated for a preset period, a warning beep will sound, alerting the radio user to check-in. If the radio user does not check in before the preset time runs out, the radio automatically sends out an emergency signal.

The F5121D: a multitude of advantages because its IDAS

Advantage 1: Digital/analog Mixed Mode

The IC-F52121D series can receive analog and digital signals on a single channel and automatically selects the received mode to reply to the received call, while the talk back timer remains. It's a smart way to grow into digital radio – at your own pace, as your budget and comfort allow.

Advantage 2: Digital and Analog Individual/Group Call 

The IC-F5121D series allows you to call individual or group users. The radio automatically sends own ID number when the PTT button is held down. The alias name or individual/group ID is displayed on the LCD while receiving a message allowing you to identify who is calling.

Advantage 3: Status Message and Short Data Message

Up to 100 status conditions can be set and sent with voice call. Also, you can request another IDAS radio to send their status and receive it. Up to 100-character of short data message can be sent and received. To send more than 9-character short data message, PC connection is required.

Advantage 4: GPS Capability 

When used with an external GPS receiver, the IC-F5121D series can transmit accurate position data for use with vehicle management applications.

Advantage 5: Multi-Site Conventional Mode 

When using the IC-F5121D series in IDAS multi-site conventional mode, the IC-F5121D can communicate with other IDAS radio users working with other repeater sites and/or virtual radio/PC dispatch stations on the IDAS network.

IDAS Single-Site Trunking 

The IC-F5121D series can be used in an IDAS single-site trunking system. The IDAS trunking system is distributed with no dedicated control channel, so more voice traffic channels are available for increased system capacity.

*All advantages shown represent possible system configurations. Ask your Icom dealer to configure an IDAS system that works best for you. Note: Private IP Network or VPN Tunnels through the Internet with static endpoints.
