hours in order to fully charge both batter y packs to peak capacity .
The charger supplied with this system is designed to recharge
your batteries at a rate of 5 0 mA for the transmitter and
50 mA (1 20 mA for helicopter) for the receiver batter y pack.

T ransmitter Polarity
The center pin on all JR Remote Control Systems is negative.
Therefore, the center pin on all JR chargers is negative, not
positive. This is dif ferent from many other manufacturers’
chargers and radio systems. Beware of improper connections
based on “color coded” wire leads as they do not apply in this
instance. Y ou must make sure that the center pin of your JR
transmitter is always connected to the negative voltage for
correct polarity hookup.

The pilot lamps should always be ON during the charging
operation. If they’re not, check to make sure that both the
transmitter and receiver are switched OFF .
Do not use this charger for equipment other than JR. The
charging plug polarity may not be the same and equipment
damage can result.
Do not use other manufacturers’ after-market accessories that
plug into the transmitter’
s charging jack. If you do, any damage
that results will not be covered by the warranty . If you are unsure
of compatibilities with your radio, seek exper t advice before
doing anything to avoid possible damage.
During the charging operation, the charger’ s temperature is
slightly elevated. This is nor mal. Also, note that the voltage
shown on the charger is higher than the batter
y in use. This
voltage cannot be measured with a voltmeter . Only current can
be measured with any accuracy using this type of charger .
Be sure to use the proper charge rate (1 20 mA) when using
batter y packs of 1 000 mAh or larger for your receivers.
