IMPORTANT
READ ALL INSTRUCTIONS carefully and
completely before using this charger.
SAVE THIS INSTRUCTION MANUAL—This
instruction manual contains important operating instructions
for the BC-121N/BC-121NA
By installing desktop charger adapters, the charger
rapidly charges up to six Ni-Cd or Ni-MH battery packs
simultaneously in 1 ~ 2 hours, or Li-ion battery pack in 2 ~ 3
hours.
Appropriate desktop charger adapters must be purchased
separately for charger to charge your Icom battery packs.
See your transceiver’s instruction manual for desktop
charger adapter details.

WORDDEFINITION
RDANGER!
RWARNING!
CAUTION
NOTE
BATTERY MEMORY EFFECT
The full charge capacity of Ni-Cd rechargeable batteries
may be reduced if repeatedly charged with only partial
discharge periods. This is called the battery memory
effect. If the battery capacity seems lower than new,
discharge the battery pack (example: connect to a
transceiver and leave the transceiver’s power ON all day)
then charge fully again. When the capacity is still low, a
new battery must be purchased.
Icom is not responsible for the destruction or damage to the Icom
transceiver, if the malfunction is because of:
• Force majeure, including, but not limited to, res, earthquakes,
storms, oods, lightning, other natural disasters, disturbances,
riots, war, or radioactive contamination.
• The use of Icom transceivers with any equipment that is not
manufactured or approved by Icom.
Personal death, serious injury or an
explosion may occur.
Personal injury, re hazard or electric
shock may occur.
Equipment damage may occur.
If disregarded, inconvenience only. No risk
of personal injury, re or electric shock.
PRECAUTIONS
R DANGER! Charge only specied Icom Ni-Cd, Ni-MH,
or Li-ion rechargeable batteries. Never charge or use an
alkaline, dry cell, third-party, or counterfeit battery packs
or charger adapter. Otherwise, a re and/or explosion may
occur.
R DANGER! NEVER charge the battery packs in
areas with extremely high temperatures, such as near res
or stoves, inside a sun heated vehicle, or in direct sunlight.
In such environments, the safety/protection circuit in the
battery will activate, causing the battery to stop charging.
R DANGER! KEEP battery packs away from re. Fire
or heat may cause them to rupture or explode. Dispose of
an used battery pack in accordance with local regulations.
R WARNING! NEVER insert the battery packs (with/
without the transceiver) into the charger if it is wet or soiled.
This could corrode the battery charger terminals or damage
the charger. The charger is not waterproof.
R WARNING! NEVER charge the battery packs during
a lightning storm. It may result in an electric shock, cause
a re or damage the battery pack or transceiver. Always
disconnect the power adapter before a storm.
CAUTION: NEVER let metal, wire, and so on, touch
any internal parts of the charger.
CAUTION: NEVER charge the battery outside of the
specied temperature range: 10°C ~ 40°C (50°F ~ 104°F).
Icom recommends charging the battery at 20°C (68°F). The
battery may heat up or rupture if charged out of the specied
temperature range. Additionally, battery performance or
battery life may be reduced.
CAUTION: NEVER use the charger with the power
adapter when it is covered by objects that impede heat
dispersal.
USE IN DOORS ONLY! NEVER expose the charger
and the power adapter to rain, snow or any liquids.
Always place the charger in a secure place to avoid
inadvertent use by unauthorized person.
DO NOT modify the charger and/or power adapter. This
may cause a re hazard or electric shock.
USE only specied accessories. Using third party or
counterfeit may result in a re hazard or electric shock.
KEEP the charger away from TV sets or radios to prevent
interference.
MAKE SURE battery and charger contacts are always
clean. Otherwise, battery packs may not be charged
properly.

PRECAUTIONS (Continued)DISPOSAL
In order to get the maximum life out of your Ni-Cd batteries:
• Avoid overcharging—batteries must be removed from the
charger to stop charging. Batteries should not be charged
for more than 15 hours after the charger indicator turns
green.
• Use the batteries until they become almost completely
exhausted under normal conditions.
Be careful of the battery pack’s temperature—when
the battery pack is extremely cold (especially for Ni-MH
batteries), the charger cannot charge the battery.
When the charger is not in use, disconnect the power
adapter from an AC outlet. The power adapter consumes
power when connected to the AC outlet.
When the operating period becomes extremely short after
full charging, the battery pack has reached the end of its life
and a new battery pack must be purchased.
An appropriate desktop charger adapter must be purchased
separately to charge your Icom battery packs.
NOTE: If your battery packs seem to have no capacity
even after being fully charged, completely discharge them,
then fully charge them again. If they still do not retain
a charge (or very little), a new battery packs must be
purchased.

The crossed-out wheeled-bin symbol on your
product, literature, or packaging reminds you
that in the European Union, all electrical and
electronic products, batteries, and
accumulators (rechargeable batteries) must
be taken to designated collection locations at
the end of their working life. Do not dispose of these
products as unsorted municipal waste. Dispose of them
according to the laws in your area.
Some versions of the BC-121N/BC-121NA
which display the “CE” symbol on the serial
number comply with the essential
requirements of the 2014/30/EU directive for
Electromagnetic Compatibility. This compliance
is based upon the harmonised CENELEC generic standard
EN 61000-6-1:2007 and EN 61000-6-3:2007/A1:2011.

TIP: About the 3-pin connector
When you replace the desktop charger
adapter from a PCB type adapter to
a non-PCB type adapter, x the 3-pin
connecter to the bottom of the charger
with adhesive tape, to prevent catching
or touching the 3-pin connector’s
terminals with the adapter’s leads.

D How To Charging
1. Connect the optional OPC-656 DC power cable or
the BC-157S power adapter to the charger, as shown
below.
• No charger indicator lights up.
2. Insert a battery pack, with or without the transceiver,
into a charger charging slot.
• The charger indicator lights up in orange.
3. When the charger indicator changes to green, battery
charging is completed.
• But it is still charging in the trickle charge mode when
charging Ni-Cd or Ni-MH battery pack.
CAUTION: The transceiver
power must be turned OFF
during charging, otherwise:
• The battery will not be
charged correctly.
• The battery life may be
shortened.
The transceiver cannot be
used even while charging.

NOTES:
For Ni-Cd/Ni-MH battery packs:
The charger rapidly charges a battery pack to a specied
level, not a completed level, to prevent over-charging.
After the charger indicator turns green, leave the battery
pack in the charger for a few more hours (up to 15 hours,
depending on battery condition) to completely charge the
battery.
For Li-ion battery packs:
Li-ion batteries are different from Ni-Cd batteries in that it
is not necessary to completely charge and discharge them
to prolong the battery life. Therefore, charging the battery
in intervals, not for extended periods, is recommended.
Use the spacer, if supplied with the charger adapter, to
charge the battery pack with or without transceiver
• When the indicator turns off while a battery
pack is inserted:
MULTI-CHARGER
May be a poor connection—reinsert the battery
pack again.
• Flashes red when the protection circuit is
activated:
- Check the power source (voltage) or
reconnect the power plug.
- The battery temperature is outside of the
charging range. (Ni-MH battery only)
