Radio Shack Twin RC Owner's Manual

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.
OWNER'S MANUAL — Please read before using this equipment.
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.
