BATTERYPACKS 3
. Battery pack charging
The optional BP-202 BATTERYPACKincludes 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.
. Charging precautions
Recommended temperature range for charging: + 50°F to +104of
(+1O°Cto + 40°C or).
. About the battery pack
0 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.

V' What;s 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. ~,

4BASIC OPERATION
. Selecting the operating channel
Push [UP]/[A] or [DOWN]/["'] keys sev-
eral times until the desired operating
channel number appears on the dis-
play.
.While pushing and holding [UP]/[A] or
[DOWN]/["'] keys, the displayed chan-
nel changes continuously until chan-
nel number" 1 " appears.
If you want to keep the automatic se-
lection, release the [UP]/[A] or
[DOWN]/["'] keys then push and hold them again.
.When displayed channel stops at channel number "01", a warn-
ing beep is emitted.

-6GROUP MODE (CTCSS)
. Setting the group code
The IC-4008A is equipped with 38 group codes. Group mode op-
eration provides communication with silent standby since you will
only receive calls from group members using the same group num-
ber.
First of all, set the same group code number for all group member's
transceivers.
Turn ON the group mode operation:
CD Push [MODE] to enter set mode.
."--- " (group mode OFF) appears on
the display.
enPush [UP]/[A] or [DOWN]/["'] to select
the desired code number.
WPush [MODE] to set the group code
number.

CD Push [MODE] to enter set mode.
.Code number disappears on the dis-
play.
enPush [UP]/[A] or [DOWN]/["'] to select

mode.

CTCSS: Continuous Tone Coded Squelch System 6
II' What is CTCSS(Continuous ToneCoded Squelch Sys-
tem) GROUP MODE?
~
J
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
output can be a problem. Note that CTCSS group mode is not
private-anyone can receive your calls.
The IC-4008A is equipped with 38 tone codes for CTCSS
GROUP MODE use. Selecting a code applies it to all 14 oper-
ating 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 sig-
nals (including noise) push and hold [MODE]. Do not use
CTCSS GROUP MODE if you want to be able to hear signals
on all channels.

J

tI' Talk Range
The IC-4008A is designed to maximize performance and im-
prove transmission range in the field. However, the single
most important factor in transmit range (talk power) is your
surrounding environment. These radios are "line of sight" ra-
dios and as such, transmission range is influenced by the de-
gree to which you can "see" the other communicating party.
Large concrete structures and heavy foliage or transmission
from inside a building or vehicle will reduce your talk power.
. Optimal range: wide, open areasfree of obstructions. (up to
2 miles)
. Medium range: large buildings or trees blocking your line of
sight.
. Minimum range: mountainous areas or areas of heavy fo-
liage.
