For organizations who run an analog radio system and must migrate to a conventional P25 digital system, Icom provides one of the best solutions. The new F1721D series mobile allows you to program P25 digital and/or FM analog mode per channel. Flash ROM capability means future upgrades and flexible customization, tailored for your system. Moreover, built-in multiple tone signaling capability and an optional voice scrambler satisfy existing analog FM system requirements. This new Icom’s range frequency coverage and rugged construction ensures a flexible, long life radio for you. Icom is the smart choice for current – and future – public safety communication needs. Project 25 (P25) Digital Features Upgrade to digital option The IC-F1721/F1821 series offers you three choices to P25 digital compatibility. Choice one is P25 compliant from the factory. Choice two is a digital hardware radio and you can install the P25 activation software (EX-2785 J01) later. Choice three is analog only radio and you can install the DSP unit, UT-120 and P25 activation software (EX-2785 J01) later. AES/DES digital encryption activation software AES and DES are encryption standards required by public safety agencies. The IC-F1721D, F1821D series provide secure encryption with DES and AES accordingly when activatied with EX-2785 J02 (for DES) and EX-2785 J03 (for AES) activation software. Interoperability The IC-F1721D, F1821D series is APCO Project 25 (P25) compliant. It ensures interoperability with other manufacturer’s P25 digital radios in conventional mode. Program digital and/or analog FM modes per channel. The mixed mode scan allows you to detect and receive both analog FM and P25 digital modes and to transmit either mode depending on programming. Mechanical and Analog Features Detachable front panel With the optional remote control kit, RMK-2 and separation cable, the front panel of the radio can be detached from the main unit. It allows you flexible installation even in limited installation space. Separation cable length is selectable from 1.9, 3.0 and 8.0m. Dot matrix, multi-function LCD Using a high contrast LCD, the IC-F1721/F1821 series shows operating channels, tone and other settings clearly under nearly any lighting conditions. With a dot matrix display, upper and lower case characters can be easily distinguished. In addition, you can change the display setting to show one line and 12 characters, or two lines and 24 characters via programming. Heavy-duty microphone, HM-148 The new heavy-duty hand microphone, HM-148, uses a dynamic design that is made to handle punishment. The oversized dimensions allow for easy use with gloves on. And the curl cord can be easily replaced by simply opening the case–easy maintenance for long term use. Rugged construction With heavy-duty construction, the IC-F1721/F1821 series is built to last. The IC-F1721/F2721 series incorporates a 4W speaker in an impact resistant polycarbonate front panel for crisp clear audio, and the IC-F1821/F2821 series has a backlit 10-keypad for extended operation. The 10-keypad version is supplied with an external speaker. Built-in versatile tone signaling Use the built-in CTCSS, DTCS, 2-Tone, or 5-Tone capability to set up your own talk groups, and have your radio standby quietly when other groups are talking. You can also set up selective calls to individuals or control a repeater. Multiple 2-Tone, Multiple 5-Tone Encode or decode up to 10 2-Tone, 8 5-Tone codes on a single memory channel. This is perfect for professionals who require multiple district paging on one channel. When a matched tone is received, the following items are programmable for each code. Bell icon Beep sound External out Answer back Auto transmit Stun Scan MDC 1200 compatible The following selective calling and ANI features are available with the built-in MDC signaling. PTT ID/Caller ID Radio check Selective call Call alert Emergency, emergency mic monitoring Radio stun/revive 500 Aliases Status/message Call log 256 memory channels, 32 zones Up to 256 memory channels can be divided into 32 memory zones, and allows you quick access to the intended channel. Tactical group function The tactical group function allows you to copy memory channels to the tactical zone (zone 32) and dynamically regroup memory channels. Using the optional zone copy cable, memory channels in the tactical zone can be transferred from a master radio to other radios. Built-in inversion type voice scrambler The IC-F1721/F1821 series includes a built-in inversion type voice scrambler in all models. When a more secure system is required, the optional voice scrambler unit UT-109 or UT-110 is available. * These voice scrambler functions are not available in digital mode. Radio stun/kill and Power-on password function The radio stun/kill functions disable a lost or stolen radio over the air, eliminating security threats from undesired listeners. The power-on password prevents unauthorized people turning on the radio. Public Address (PA) and RX speaker functions When an external loud speaker is connected with the radio, you can speak through the radio’s microphone. The RX speaker function allows you to relay the received audio over the loud speaker. Other features Microphone hanger action programmable (Scan, monitor, priority channel) Optional OPC-617 D-SUB 9 pin connector for dimmer control, modem connection D-SUB 25 pin connector for future PC connection Built-in audio compander (Analog mode only) Wide frequency coverage (136–174MHz, 400-470 and 450-512MHz) LTR® Trunking system capability with the optional UT-111 installed.
