& AS4295-1995.
CAUTIONS
R WARNING! NEVER hold the transceiver so that the
antenna is very close to, or touching exposed par ts of the
body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm
away from the lips and the transceiver is vertical.
R WARNING! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels.
Hearing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce the
volume level or discontinue use.
NEVER connect the transceiver to an AC outlet or to a
power source of more than 16 V DC. Such a connection will
damage the transceiver.
NEVER connect the transceiver to a power source that is
DC fused at more than 5 A. Accidental re verse connection will
be protected by this fuse, higher fuse values will not give any
protection against such accidents and the transceiver will be
ruined.
NEVER attempt to charge alkaline or dry cell batteries. Be-
ware that external DC power connections will charge batteries
inside the battery case.This will damage not only the battery
case but also the transceiver.

channel.
- Push [O/G] for 2 sec. to set the
channel to the priority channel.
e Push [SCN] to start group or priority scan.
- Cancelling tag channels speeds up the scan interval.
r When receiving a signal, scan pauses and resumes ac-
cording to the selected scan resume condition. (p. 10)
t Push [SCN] to stop the scan.
■ Setting scan tag
Scan tag must be set before starting scan. Tag channels are
independently set for open, group and priority scan.
q Select the desired channel.
w Push [O/G] to select the desired scan type.
e Push [SCN] for 2 sec.to set the channel as a tag channel.
- “X”appears for tag channels.
r Repeat step e to cancel the tag channel setting.
For open scan, cancel the tag channel setting to skip undesired channels such as usually busy channels. This
speeds up the scan interval. All memory channels may be
set as tag channels by default.
For group scan, set only often-used channels as tag channels. All memory channels may be set as tag channels by
default.

TONE SQUELCH OPERATION
■ Tone squelch operation
The tone squelch opens only when receiving a signal containing a matching CTCSS (subaudible) tone.Y ou can silently
wait for calls from group members using the same tone.
q Set the desired channel.
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 “TSQL”appears.
r When the received signal includes a matching tone,
squelch opens and the signal can be heard.
•When the received signal’s tone does not match, tone squelch
does not open, however, the S-indicator shows signal strength.
•To open the squelch manually, push [–].
t Operate the transceiver in the normal way.
y To cancel the tone squelch, push [–] for 2 sec.twice.
NOTE:The transceiver has 51 tone frequencies and consequently their spacing is narrow compared with units having 38 tones. Therefore, some tone frequencies may
receive interference from adjacent tone frequencies.
Tone frequencies and tone squelch ON/OFF settings are
automatically stored in memory channels for easy recall.
■ Pocket beep operation
This function uses CTCSS (subaudible) tones for calling and
can be used as a “common pager” to inform you that someone has called while you were away from the transceiver.

is necessary.Use the tone squelch at left or a CTCSS (subaudible) tone encoder (p.7).
■ Charging
precautions
NEVER attempt to charge dr y cell bat-
teries. This will cause internal liquid
leakage and damage the battery case
and transceiver.
NEVER connect two or more chargers
at the same time.
Charging may not occur under temperatures of 10°C (50°F) or over temperatures of 40°C (104°F).
When using BC-119: If the charge
indicator flashes orange, vehicle battery voltage is low and charging is
not possible. Check the vehicle battery voltage in this case.If the charge
indicator flashes red, there may be a
problem with the battery pack (or
charger). Re-insert the batter y pack
or contact your dealer.
■ Battery pack
charging
The BP-195 or BP-196
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 o vercharging.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.
D
Rapid charging with the BC-119

BATTERY PACKS
■ About the battery pack
DOperating period
Depending on the attached battery pack, the operating period
of the transceiver varies. Refer to the last page for battery
pack specifications.
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.
If the battery pack still does not retain a charge (or very little),
a new battery pack must be purchased.
■ Installing batteries in the
battery case
When using a battery case, install 8 AA (R6) size Ni-Cd or alkaline batteries as illustrated below.
q Remove the bat-
tery case from the
transceiver.
w Install 8 × AA (R6)
size Ni-Cd or alkaline batteries.
•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 external DC power, installed batteries are simultaneously
charged.
● Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.
