3BATTERY PACKS
‘‘Battery pack charging
The optional BP-202 BATTERY PACK includes rechargeable Ni-Cd
batteries and can be charged approx. 300 times. Charge the battery
pack before first operating the transceiver or when the battery pack
becomes exhausted.
If you want to be able to charge the battery pack more than 300
times, the following points should be observed:
1. Avoid overcharging. The charging period should be less than 48
hours.
2. Use the battery until it becomes almost completely exhausted
under normal conditions. We recommend battery charging just
after transmitting becomes impossible.
‘‘Battery pack life
If your battery pack seems to have no capacity even after being
fully charged, completely discharge it by leaving the power ON all
day. Then, fully charge the battery pack again.
If the battery pack still does not retain a charge (or very little), a new
battery pack must be purchased.
‘‘Battery pack CAUTION
NEVER short the terminals of the battery pack (or charging termi-
nals of the transceiver). Also, current may flow into nearby metal
objects, so be careful when placing battery packs (or the trans-
ceiver) in handbags, etc. Simply carrying with metal objects may
cause a short circuit. This will damage not only the battery pack but
also the transceiver.

4BASIC OPERATION
✔ What is squelch ?
A squelch circuit allows you to mute undesired noise while re-
ceiving no signal and emit audio while receiving signals.
This provides quiet standby. The [MODE] key changes the
squelch setting. This is useful to listen to weak signals that do
not open the squelch.
‘‘Power ON

BASIC OPERATION
‘‘Selecting the operating channel
Push [UP/Y] or [DOWN/Z] keys sev-
eral times until the desired operating
channel number appears in the dis-
play.
• While pushing and holding [UP/Y]
or [DOWN/Z] keys, the displayed
channel changes continuously until
channel number “1” appears.
• When the displayed channel stops
at channel number “1”, a confirmation beep is emitted.
NOTE:
• The transceiver has 40 operating frequency channels.
• The selected channel is memorised when you turn off the
transceiver.
• The transceiver has an auto power save function to conserve
the battery power. The power save function activates automat-
ically when no signal is received for 5 sec., or 5 sec. after key
operation is completed.

5RECEIVE AND TRANSMIT
qPush [MODE] for 1 sec. to open
the squelch.
• Adjust volume to the desired
audio level. (See p. 8)
w
Select a desired operating channel.
When a signal is received:
• “ ” appears in the display.
• Squelch opens and audio is emit-
ted from the speaker.
• Further adjustment of [VOL] may
be necessary at this point.
ePush and hold [PTT] to transmit

Time-Out Timer (TOT)
The transceiver has a time-out timer function. This function pre-
vents continuous, extended transmissions. This timer turns the
transmission OFF 3 min. after it starts.
A warning beep sounds 10 sec. before the limit is reached, and
the time-out timer turns OFF the transmission automatically.An-
other beep sounds to announce the end of the transmission.
Busy indicator
appears.

RECEIVE AND TRANSMIT
✔ Talk Range
The IC-40Jr is designed to maximize performance and improve
transmission range in the field. However, the single most impor-
tant factor in transmit range is your surrounding environment.
These radios are “line of sight” radios and as such, transmission
range is influenced by the degree to which you can “see” the
other communicating party. Large concrete structures and heavy
foliage or transmission from inside a building or vehicle will re-
duce your talk range.
• Optimal range : wide, open areas free of obstructions.
• Medium range : large buildings or trees blocking your line of
sight.
• Minimum range : mountainous areas or areas of heavy foliage.

12
6REPEATER OPERATION
A repeater amplifies received signals and re-transmits them on a
different channel, allowing you to communicate over greater dis-
tances with improved reliability. When using a repeater, the transmit
channel is shifted from the receive channel by 30 channels. Please
ask you dealer regarding repeater availability in your local area.
q
Push [UP/Y] or [DOWN/Z] to se-
lect the desired channel from 1 to 8.
• If group code appears next to the
operating channel number, push
[MODE], then select “ -–– ” with
[UP/Y] or [DOWN/Z] to cancel
the group mode (p. 14).
RWARNING!
As group mode is not compati-
ble with repeater operation, no
audio will be heard.
wPush [POWER] momentarily to set repeater mode.
• “RPT” appears in the display.
• The duplex setting affects the selected channel only and the
setting is retained after channel selection.
ePush and hold [PTT] to transmit.
• The displayed channel automatically changes to the transmit
channel (repeater input channel).
rRelease [PTT] to receive.
tTo cancel the duplex setting, push [POWER] momentarily on the
desired channel.

transceivers.
To turn ON the group mode operation:
qPush [MODE] to enter set mode.
• Operating channel number disappears
and “ -–– ” (group mode OFF) appears in
the display.
wPush [UP/Y] or [DOWN/Z] to select the
desired code number.
ePush [MODE] to set the group code num-
ber.
To cancel the group mode operation:
qPush [MODE] to enter set mode.
• Operating channel number disappears
from the display.
wPush [UP/Y] or [DOWN/Z] to select “ -–– ”
(group mode OFF).
ePush [MODE] to cancel the group mode.
IMPORTANT!: Before transmitting, make sure the channel you
will operate with the group mode is clear by pushing [MODE] for
1 sec., to prevent interference to other stations.
NOTE: Only stations with the same group channel number can
be heard during group mode operation, even when the busy in-
dicator appears in the display.

✔ What is CTCSS (Continuous Tone Coded Squelch Sys-
tem) GROUP MODE ?
CTCSS (Continuous Tone Coded Squelch System) GROUP
MODE allows communication with silent stand by. Only signals
containing your group code can open the squelch.
This conveniently eliminates unwanted audio and is useful in
group activities or security related activities where unwanted out-
put can be a problem. Note that CTCSS group mode is not pri-
vate— anyone can receive your calls.
The IC-40Jr is equipped with 38 tone codes for CTCSS GROUP
MODE use. Selecting a code applies to all 40 operating channels.
Each push of [PTT] superimposes your group code over your
transmit signal; and, only signals containing the same code can
open your squelch. To temporarily hear all signals (including
noise) push and hold [MODE]. Do not use CTCSS GROUP
MODE if you want to be able to hear all signals on the channel.

9RING FUNCTION
