User manual ICOM IC-F2821 BROCHURE

[. . . ] Moreover, built-in multiple tone signaling capability and an optional voice scrambler satisfy existing analog FM system requirements. This new Icom's 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. VHF AND UHF TRANSCEIVERS without 10-keypad (VHF P25 digital version) (VHF Analog version) (UHF P25 digital version) (UHF Analog version) VHF AND UHF TRANSCEIVERS with 10-keypad (VHF P25 digital version) (VHF Analog version) (UHF P25 digital version) (UHF Analog version) Upgrade to digital option The IC-F1721/F1821 series offers you three choices to P25 digital compatibility. [. . . ] In addition, you can change the display setting to show one line and 12 characters, or two lines and 24 characters via programming. 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. 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 · Answer back · Stun · Beep sound · Auto transmit · Scan · External out 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. Two line setting display example Heavy-duty microphone, HM-148 The new heavy-duty hand microphone, HM-148, uses a dynamic design that is made to handle punishment. And the curl cord can be easily replaced by simply opening the case ­ easy maintenance for long term use. 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. 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 (136­174, 400­ 470 and 450­512MHz) 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. Rugged construction With heavy-duty construction, the ICF1721/F1821 series is built to last. The ICF1721/F2721 series incorporates a 4W · LTR® Trunking system capability with the optional UT-111 installed. · PC programming capability VHF AND UHF TRANSCEIVERS GENERAL · Frequency range : IC-F1721/D, F1821/D 136­174MHz IC-F2721/D, F2821/D 400­470MHz, 450­512MHz · Number of channels : 256 channels/ 32 zones · Channel spacing : 12. 5/25kHz, 15/30kHz · PLL channel step : 2. 5kHz, 3. 125kHz (VHF) 5kHz, 6. 25kHz (UHF) · Antenna impedance : 50 · Operating Temp. range : ­30°C to +60°C ; ­22°F to +140°F · Power supply requirement : 13. 6V DC nominal · Current drain (approx) : Tx 50W/45W 14. 0A Rx Max. audio 1200mA Stand-by 600mA · Dimensions (W×H×D) : 175×45×170 mm (projections not included) ; 67/8 ×125/32 ×611/16 in · Weight (approx. ) : 1. 5kg; 3. 3lb TRANSMITTER · Output power (approx) : 50W (VHF) 45W (UHF) · Max. frequency deviation : ±5. 0/2. 5kHz (Wide/Narrow) · Frequency error : ±2. 0ppm · Spurious emissions : 75dB typ. microphone impedance : 600 (8-pin modular) · Intermodulation : Analog 77/75dB typ.
