Optional internal unit
The IC-F5021 series has a 40-pin option
slot for adding an optional unit. Optional
voice scrambler units, UT-109R or UT-
110R provide secure private conversa-
tion.
External memory channel
control with optional ACC cable
With the optional OPC-1939 D-SUB 15-
pin ACC cable, the IC-F5021 series can
be programmed to control an operating
channel from an external device
(up to 16
preprogrammed channels)
. The ACC con-
nector also provides an ignition sensing
function, external PTT, PC command,
horn honk, audio output and modulated
signal input depending on programming.

128 memory channels
128 channels
(Max.)
separated into 8
memory zones. Memory channels can
be identified with the 8-character chan-
nel name and selected easily with the up/
down buttons.
Front mounted speaker
4 watts
(typ.)
front mounted speaker de-
livers clear and loud audio. With the
speaker facing the operator, audio can
be clearly heard without impediment dur-
ing operation.
6 programmable buttons
A pair of up/down and P0–P3 function
assignable buttons allow you to custom-
ize functions to meet specific needs. An
independent volume knob offers simple,
convenient operation.
MIL grade rugged construction
The tough aluminum die-cast chassis
and polycarbonate front panel have been
tested to the MIL standard 810F. With this
heavy-duty construction, the IC-F5021
series provides reliable operation over
the long term in all manners of rugged
environments.
Most popular signalings built-in
Use the built-in 2-Tone, 5-Tone, CTCSS
and DTCS capabilities as standard to
set up your own talk groups, PTT ID and
quiet stand-by when others are talking.
The IC-F5021 series has added CTCSS/
DTCS high speed decode and 2-Tone
decode accuracy.
MDC 1200 compatible
The following MDC features are available
with the built-in MDC signaling.
• PTT ID
(TX/RX)
• Radio check
(RX)
• Radio stun
(RX)
• Radio revive
(RX)
• Emergency TX/RX
(No ACK)
• 5 alias table
(Max.)
Multiple 2-Tone, Multiple 5-Tone
Up to ten 2-Tone and eight 5-Tone codes
can be decoded on a channel. When a
matched tone is received, the following
items are programmable for each code.
• Beep sound • Answer back
• Scan
• Bell icon
• Radio stun/kill/revive
Radio kill, stun and revive
The radio kill/stun functions disable a lost
or stolen radio over the air, eliminating
security threats from undesired listeners.
When the stun command is received, all
functions will be temporary locked out
until the revive command is received or
the unlock password is entered.
Lone worker function
When the radio is not operated for a pre-
set period, the radio sounds a beep and
requires you to push any button. If the
radio is still not operated for a specified
wait period, an emergency signal auto-
matically transmits and informs co-work-
ers that something may have happened
to the individual worker.
Mode dependent scan
In the mode dependent setting, the scan-
ning setting is dependent on the oper-
ating channel. When you change the
operating channel, the scanning list au-
tomatically changes to the list set for that
channel. It is convenient when you move
to a different operating area and change
operating channel, you don’t have to
change the scanning setting.
Tx channel setting and
Talk back function
The Tx channel setting allows you to
program a transmission channel while
scanning. Start channel, last detected
channel, priority and preprogrammed
channel are selectable. Prior to the Tx
channel setting, the talk back function
allows you to talk on the last detected
channel, while scanning resumes after a
preset time. The user can easily make a
quick response with this function.
Wide frequency coverage
The IC-F5021 series covers a wide fre-
quency range in one version
(VHF 136–
174 MHz, UHF 400–470 or 450–512 MHz)
.
The IC-F5021/F6021 series is designed
to be a companion to our IC-F3031/F4031
series waterproof transceiver. The num-
ber of channels and banks, signaling
formats, programming software and
voice scrambler are compatible. Take
advantage of the shared functionality to
complete your communications require-
ments.
