IMPORTANT
READ ALL INSTRUCTIONS carefully before using the IC-41PRO UHF transceiver.
KEEP THIS ADVANCED MANUAL, as it contains important operating information that may be useful in the
future.
The BASIC MANUAL is supplied with the transceiver.
This ADVANCED MANUAL describes the radio as supplied in standard factory default setting. However, the settings
on your transceiver may differ if it has been customised by your dealer. For details, refer to your authorised Icom

The password is a 4 digit code (example: 1234).
➥ Push the corresponding keys to enter your password.
• Note that each key represents two digits. That means,
“3764” and “8769” are entered in exactly the same way
(requires no multiple or extended pushing.)
• The entered password will not be displayed.
• If “PASSWD” does not disappear after entering, the
entered password is incorrect. Turn OFF the transceiver,
and then try again.

Keylock
Hold down for 2 seconds to electronically lock
[ROTARY SELECTOR] and all keys except [PTT],
[Side 1], [TOP], (When in the Function mode) and
to prevent accidental channel changing or function
access.
To lock the keys:
➥ Hold down for 2 seconds to lock.
• “ ” is displayed.
To unlock the keys:
➥ Hold down for 2 seconds again to unlock.
• “ ” disappears.
D Non-locked keys
Even when the Keylock function is ON, you can use
the following keys for certain conditions.
[PTT]: You can hold down to transmit, and release to
receive.
[Side 1]: You can push to turn the Monitor function ON
or OFF.
[TOP]: You can push to change between Normal
mode and Function mode.
: In the Function mode, you can hold down for
2 seconds to transmit the selected Selcall
code, when a CB channel is selected.
: You can hold down for 2 seconds to turn OFF
the Keylock function.
Channel selection
There are 80 UHF CB channels and you have access
to all 80 channels, including designated repeater channels. You can select between them to communicate with
a specific person(s). The IC-41PRO is also capable of
being set with an additional 35 receive only channels,
using the optional cs-41PrO clOning sOftware.
➥ Rotate [ROTARY SELECTOR] to scroll through the
selectable channels.

Zone selection
(
Selectable only when more than 2 zones are set, using the
optional CS-41PRO clOning sOftware)
A zone enables you to allocate several channels into
a logical group. This is useful if you want to simplify
communications, particularly in commercial or convoy
applications, or if you want to separate out the receive
only channels to be scanned separately from CB
channels.
q Push [TOP] to enter the Function mode.
w Hold down
selection mode.
e Rotate [ROTARY SELECTOR] to select the desired
zone, and then push to set.
NOTE:
• The transceiver remains in the selected mode when
turned OFF and then ON again.
• CB-05, CB-R05 and CB-35 channels are for emergency
use, and are required to be left open for only emergency
use. CB-22 and CB-23 are used for only receiving.
for 2 seconds to enter the zone
Priority channel
The Priority channel enables you to have quick access
to a specific channel. Only one channel can be set as
the Priority channel. “P” is displayed when the Priority
channel is set.
Monitor
The Monitor function opens the Squelch or Tone
squelch, enabling you to receive weak signals. This
enables quick access to the open squelch setting.
➥ To turn the Monitor function ON or OFF, push [Side 1].
• “ MONI ON” or “MONI OF” is displayed when the function
is turned ON or OFF.
Squelch
In order to clearly receive signals, set the squelch
level to suit your environment. This eliminates
background noise when there are no signals preset.
A higher level is better for inner cities or noisy areas,
and a lower level is more beneficial in quiet, rural or
country areas.
Setting the squelch level:
q Push [Side 2] to enter the squelch setting mode.
w Rotate [ROTARY SELECTOR] to set the squelch
level to between 0 and 9.
• 0= lowest squelch level, 9= highest squelch level
e Push [Side 2] to set the selected squelch level and
exit the setting mode.
Information
You can also set the squelch level in the Set mode.
See page 5 for details.
D Setting the Priority channel
q Rotate [ROTARY SELECTOR] to select a desired
channel.
w Hold down for 2 seconds to set the selected
channel as the Priority Channel.
• “P” is displayed.
D Switching to the Priority channel
➥ Push to switch from a displayed channel to the
Priority channel. “N/A” is displayed when the Priority
channel is not set.
D Cancelling the Priority channel
➥ Push [TOP] to enter the Function mode, and then
hold down for 2 seconds to cancel the Priority
channel setting.
• “P” disappears.

REPEATER OPERATION
Repeater operation
Repeaters extend the operational range of the transceiver by retransmitting the signals it receives. Repeaters are
usually located on the top of a building or a mountain, as the elevation increases their effectiveness, allowing the user
to transmit and receive over greater distances. During Simplex operation, transceivers transmit and receive on the
same frequency. During Duplex operation (using a repeater) transceivers transmit and receive on different frequencies. It automatically does this when one of the repeater channels is selected.
Accessing a repeater:
To use a repeater,you need to select a repeater channel (Repeater CH 1 to 8, and 41 to 48).
You can search for any accessible repeaters in your local area by using the Repeater scan. (p. 10)
➥ Rotate [ROTARY SELECTOR] to select a repeater channel.

Repeater scan
The Repeater scan is used not only to search for a

a repeater by automatically transmitting in sequence.
The Repeater scan detects repeaters that can be
accessed in the area, even if the repeater is not used.
The Repeater scan detects signals only on
channels 1 to 8 (channel 5 not included) and 41 to
48.
The scan will stop if any activity is detected on a
repeater channel, even if a repeater is not present.
Activity such as stations operating in Simplex mode
on a repeater transmit channel may give a false

Tone Squelch
TONE SQUELCH AND POCKET BEEP
The transceiver is equipped with 51 CTCSS tone

CTCSS/DTCS
operation enables you to communicate in the silent
standby mode, since you will only receive calls from
group members using the same CTCSS tone frequency
or DTCS code.
NOTE: Channels 5 and 35 are used for the
emergency channels, and the CTCSS/DTCS
function is not selectable on those channels.
Information
• Selectable CTCSS tone frequencies and DTCS codes are
listed to the right.
• The transceiver has 51 tone frequencies and consequently
their spacing is narrow compared to units having 38 tones.
Therefore, some tone frequencies may receive interference
from adjacent tone frequencies.
