*The battery pack (BP-195 or BP-196) may differ depending on  
version. Some versions do not include a battery pack and wall  
charger.  
DO NOT allow children to play with any radio equipment  
containing a transmitter.  
DO NOT operate the transceiver near unshielded electrical  
blasting caps or in an explosive atmosphere.  
AVOID using or placing the transceiver in direct sunlight or  
in areas with temperatures below 10°C or above +60°C.  
The use of non-Icom battery packs/chargers may impair  
transceiver performance and invalidate the warranty.

Even when the transceiver power is OFF, a slight current still  
flows in the circuits. Remove the battery pack or case from  
the transceiver when not using it for a long time. Otherwise,  
the battery pack or installed dry cell batteries will become ex-  
hausted.

To attach:  
Slide the belt clip into the plastic loop on the back of the bat-  
tery case/pack.  
Insert the supplied antenna into the an-  
tenna connector and screw down the an-  
tenna as shown at right.  
Keep the jack cover attached when jacks  
are not in use to avoid bad contacts from  
dust and moisture.  
To remove:  
Push the top of the belt clip towards the transceiver and at  
the same time, push it downward and free of the plastic loop.  
DBattery pack replacement  
To remove:  
Push and hold the bat-  
tery release downwards,

Repeater operation  
A repeater amplifies received signals and retransmits them  
on a different channel, allowing you to communicate over  
greater distances with improved reliability. When using a re-  
peater, the transmit channel is shifted from the receive chan-  
nel by 30 channels.  
DSetting CTCSS tones for  
[
repeater and tone squelch  
operation  
Repeaters may require CTCSS (subaudible) tones to be ac-  
cessed. CTCSS tones are superimposed over your normal  
signal and must be set in advance.  
q Select the receive channel from 1 to 8 (repeater output  
channel).  
This setting is commonly used for the tone squelch operation.

Open scan searches for transmitted signals automatically and  
makes it easier to locate new stations for contact or listening  
purposes.

ority scans. Initially, all channels may be set as tag channels  
for all scans.

Tone squelch operation  
Pocket beep operation  
The tone squelch opens only when receiving a signal con-  
taining a matching CTCSS (subaudible) tone.You can silently  
wait for calls from group members using the same tone.  
This function uses CTCSS (subaudible) tones for calling and  
can be used as a common pagerto inform you that some-  
one has called while you were away from the transceiver.  
q Set the desired channel.  
w Set the desired CTCSS tone in set mode.

w Set the desired CTCSS tone in set mode.  
See p. 7 for tone frequencies and programming information.  
e Push [] for 2 sec. several times until TSQLëappears  
in the function display.  
When the received signals tone does not match, tone squelch  
does not open, however, the S-indicator shows signal strength.  
To open the squelch manually, push [].  
r When a signal with the correct tone is received, the  
transceiver emits beep tones and ashes TSQLë.”  
t Push [PTT] to answer or push [] to stop the beeps and  
ashing.  
t Operate the transceiver in the normal way.  
y To cancel the tone squelch, push [] for 2 sec. twice.  
Tone squelch is automatically selected.  
NOTE:The transceiver has 51 tone frequencies and con-  
sequently their spacing is narrow compared with units hav-  
ing 38 tones. Therefore, some tone frequencies may  
receive interference from adjacent tone frequencies.  
DCalling a waiting station using pocket beep  
A subaudible tone matched with the stations tone frequency  
is necessary. Use the tone squelch at left or a CTCSS (sub-  
audible) tone encoder (p. 7).  
Tone frequencies and tone squelch ON/OFF settings are  
automatically stored in memory channels for easy recall.

One AD-81 and an AC adapter (may be  
supplied with the BC-119 depending on  
version) are additionally required.  
NEVER attempt to charge dry cell bat-  
teries. This will cause internal liquid  
leakage and damage the battery case  
and transceiver.  
The BP-195 or BP-196 BATTERY PACK in-  
cludes rechargeable Ni-Cd batteries  
and can be charged approx. 300 times.

Check orientation  
If you want to be able to charge the bat-  
tery pack more than 300 times, the fol-  
lowing points should be observed:  
1.Avoid overcharging. The charging pe-  
riod should be less than 48 hours.  
2.Use the battery until it becomes al-  
most completely exhausted under  
normal conditions. We recommend  
battery charging just after transmitting  
becomes impossible.

About the battery pack  
Installing batteries in the  
battery case  
When using a battery case, install 8 AA (R6) size Ni-Cd or al-  
kaline batteries as illustrated below.  
DOperating period  
Depending on the attached battery pack, the operating period  
of the transceiver varies. Refer to the last page for battery  
pack specications.  
q Remove the bat-  
tery case from the  
transceiver.  
DBattery pack life  
If your battery pack seems to have no capacity even after  
being fully charged, completely discharge it by leaving the  
power ON overnight. Then, fully charge the battery pack  
again.  
w Install 8 × AA (R6)  
size Ni-Cd or alka-  
line batteries.  
If the battery pack still does not retain a charge (or very little),  
a new battery pack must be purchased.  
Be sure to observe  
the correct polarity.  
NEVER connect DC power to the transceiver when in-  
stalling dry cell or alkaline batteries. Such a connection will  
damage the transceiver.  
Be careful of battery overcharging. When operating via ex-  
ternal DC power, installed batteries are simultaneously  
charged.  
Keep battery contacts clean. Its a good idea to clean bat-  
tery terminals once a week.

has a time-out timer. This timer turns a transmission OFF 1,  
2, 3 or 4 min. after it starts. This timer can be cancelled.  
Power saver  
The power saver function reduces the current drain to con-  
[

w Push [LOW] several times until PSappears.  
e Push [Y] or [Z] to turn the power saver ON or OFF, re-  
spectively.  
Approx. 5 sec. before the time-out time elapses, the trans-  
ceiver emits a beep tone.
