Twin RC Charging Unit
Your RadioShack Twin RC Charging Unit is perfect for charging re-
mote controlled racing car batteries. It can charge two 7.2-volt or
9.6-volt Ni-Cd or Ni-MH battery packs one at a time. It only takes 3
hours to charge a Ni-Cd battery (1000 mAh, 9.6V or 2000 mAh,
7.2V), and 4.5 hours for a Ni-MH battery (1600 mAh, 9.6V or 3000
mAh, 7.2V). Its other features include:
Charge Indicators — light when the battery packs are charging, au-
tomatically turn off when the battery packs finish charging, and flash
if the battery packs fail to charge, indicating a problem with the bat-
tery (the battery is not properly connected, or needs to be replaced,
for example).
Optional DC Operation — lets you charge batteries through a 12 V
DC cigarette-lighter plug socket with a 12VDC adapter (not sup-
plied).
Automatic Charging Current Selection — automatically detects
the battery voltage and selects the appropriate charging current.
Reverse Polarity Protection — protects the charger and batteries
against incorrectly installed batteries.
Short Circuit Protection — protects the charger and batteries
against shorted batteries.
Automatic Power-Off — turns off the charger to prevent overcharg-
ing.
Overcurrent Protection — controls the charging current.
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS!
Warning: To reduce the risk of fire or electric shock, carefully follow
these instructions.
This manual contains important safety and operating instructions for
your charger. Before using the charger, read all the instructions and
cautionary markings in this manual and on the charger, the batteries
to be charged, and the products that use the batteries.
Warning: To reduce the risk of injury:
• Charge only Ni-Cd or Ni-MH rechargeable batteries. Other
types of batteries could burst, causing personal injury and dam-
age.
• Unplug the charger from the outlet before attempting any main-
tenance or cleaning.
• Do not disassemble the charger; take it to a qualified service
technician when service or repair is required. Improper reas-
sembly may result in a risk of electric shock, or injury to per-
sons.
• Do not use an attachment not recommended or sold by
RadioShack as this could result in a risk of fire, electric shock,
or injury to persons.
Caution: To reduce the risk of damage:
• Do not expose the charger to rain or excessive moisture.
• Never operate the charger if it has received a sharp blow, or
been dropped or damaged in any way. Have it repaired by qual-
ified service personnel.
• Do not operate the charger if the cord or plug of the supplied
AC/DC adapter is damaged. Have the adapter repaired. Never
alter the cord or plug. If it does not fit into the AC outlet, have a
qualified service technician install the proper outlet. Improper
connection can result in an electric shock.
• Disconnect the charger by pulling the adapter’s plug rather than
the cord.
• Do not use an extension cord. Its use could result in fire or elec-
tric shock.
• Never use the charger as a DC power source for any electrical
equipment.
OPERATION
Warning: Connect or disconnect the battery connector only when
the charger is disconnected from AC power.
Cautions:
• Do not try to charge batteries other than those listed in this
manual, or use procedures other than those described in this
manual.
• Charge batteries in an area between 60 and 85 °F. Batteries do
not fully charge when they are cold. If the area is too warm, the
batteries can permanently lose their ability to charge.
WARNING: To reduce the risk of fire or shock hazard, do not expose
this product to rain or moisture.
CAUTION
RISK OF ELECTRIC SHOCK. DO NOT OPEN.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO
NOT REMOVE COVER OR BACK. NO USER-SERVICEABLE
PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSON-
NEL.

• To prevent damage to your charger and risk of shock, always
unplug the AC/DC adapter from the AC outlet before you unplug
it from the charger.
1. Insert the battery connector of the bat-
tery pack you want to charge into the
charging jack.
Note: If the connector does not fit, turn it
over and try again. Do not force it.
2. If you charge only one battery pack, you
can insert it into either CHANNEL 1 or
CHANNEL 2.
You can insert two 7.2V, two 9.6V, or one 7.2V and one 9.6V Ni-
Cd or Ni-MH battery packs into the charger. If you insert both
battery packs into the charger before plugging in the charger,
the charger charges the battery pack in Channel 1 first, then the
one in Channel 2. If you insert the battery packs after the
charger is plugged in, the charger charges the battery pack that
was inserted first, then charges the other one.
3. Insert the adapter’s barrel plug into the DC jack on the back of
the charger, then plug the adapter into a standard AC outlet.
Caution: You must use a Class 2 power source that
supplies 12V DC and delivers at least 1200 mA. Its
center tip must be set to positive and its plug must fit
the charger's 12V DC jack. The supplied adapter meets these
specifications. Using an adapter that does not meet these spec-
ifications could damage the charger or the adapter.
You can also power the charger by vehicle power, using a ciga-
rette-lighter plug cable, RadioShack Catalog Number 270-1533
or 270-1534 (not supplied, available at your local RadioShack
store). Insert the cable’s barrel plug into the DC jack of the
charger, then insert the cigarette-lighter plug into your vehicle’s
cigarette lighter socket.
Notes:
• It is normal for the batteries to become warm while charging.
• The indicator for the channel you are using lights when the
battery pack is charging and automatically turns off when the
battery pack finishes charging.
• If the indicator flashes, check the battery connection. If it still
flashes, the battery pack might need to be replaced. Try
charging a different battery pack. If the charger still does not
work, take it to your local RadioShack store for assistance.
4. When the indicators turn off, unplug the adapter from the AC
outlet, or unplug the cigarette-lighter plug from vehicle power,
then unplug the barrel plug from the charger’s DC jack. Then
disconnect the battery packs.
CARE
Keep the charger dry; if it gets wet, wipe it dry immediately. Use and
store the charger only in normal temperature environments. Handle
the charger carefully; do not drop it. Keep the charger away from
dust and dirt, and wipe it with a damp cloth occasionally to keep it
looking new.
Modifying or tampering with the charger’s internal components can
cause a malfunction and might invalidate its warranty. If your charg-
er is not performing as it should, take it to your local RadioShack
store for assistance.
