Note: It is imperative that you fully charge both the transmitter
and the receiver battery packs prior to each flight. To do so, leave
the charger and batteries hooked up overnight (16 hours). The
first charge should be approximately 20–24 hours in order to
fully charge both battery packs to peak capacity.
The charger supplied with this system is designed to recharge
your batteries at a rate of 50 mAh for the transmitter and
120 mAh for the receiver battery pack.
Transmitter Only
The center pin on all JR remote control systems transmitter
charge jacks is negative. Therefore, the center pin on all JR trans-
mitter chargers is negative, not positive. This is different 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. You must make certain that the
center pin of your JR transmitter is always connected to the nega-
tive voltage for correct polarity hookup.
Note: Please refer to the following diagrams:
Red=positive
Brown=negative
Orange=signal
Please note this is different than transmitter charge polarity.
The pilot lamps should always be “on” during the charging oper-
ation. If not, check to make sure that both the transmitter and
receiver are switched “off.”
Do not use the charger for equipment other than JR. The charging
plug polarity may not be the same and equipment damage can
result.
During the charging operation, the charger’s temperature is
slightly elevated. This is normal.
Be sure to use the proper charger (120mAh) when using battery
packs of 1000mAh or larger for your receivers.
