CHARGING THE Ni-Cd BATTERIES

Charging Your System's Batteries
1. Connect the transmitter charging jack and airborne Ni-Cd batteries to the transmitter and receiver connectors of the charger.
2. Plug the charger into a wall socket.
3. Check that the charger LED lights.
Receiver Ni-Cd battery
You should fully discharge your system's Ni-Cd batteries periodically to prevent a condition called memory. For
example, if you only make two flights each session, or you regularly use only a small amount of the batteries' capacity , the
memory effect can reduce the actual capacity even if the battery is fully charged. You can cycle your batteries with a commercial
cycling unit*, or by leaving the system on and exercising the servos by moving the transmitter sticks until the transmitter shuts
itself off. Cycling should be done every four to eight weeks, even during the winter or periods of long storage. Keep track of the
batteries' capacity during cycling; if there is a noticeable change, you may need to replace the batteries.
*Note that your 7C transmitter system is protected from accidental reverse polarity, power surges and other electrical
damage by a diode. The transmitter battery must be removed from the system to cycle. The battery easily unplugs from the
battery compartment and has a standard J-plug for easy cycling.
DO NOT attempt to charge your 8-cell transmitter pack on the 4-cell receiver plug of the wall charger!

The initial charge, and any charge after a complete discharge,
should be at least 18 hours to ensure full charge. The batteries
should be left on charge for about 15 hours when recharging the
standard NR-4J, NR-4RB and NT8S600B Ni-Cd batteries.
We recommend charging the batteries with the charger
supplied with your system. Note that the use of a fast charger
may damage the batteries by overheating and dramatically
reduce their lifetime.
