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.
