Section 3: Battery Charging

Transmitter/Receiver

NOTE: It is imperative that you fully charge both the
transmitter and the receiver battery packs prior to
each flying session. To do so, using the included wall
charger, leave the charger and batteries connected
overnight (16 hours). The first charge should be
approximately 0– hours in order to fully charge
both battery packs to peak capacity.

Transmitter Polarity

The center pin on all JR
Therefore, the center pin on all JR 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
may not apply in this instance. You must make sure that
the center pin of your JR transmitter is always connected
to the negative voltage for correct polarity hookup.

Charger

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. During the charging operation, the charger's
temperature is slightly elevated. This is normal.
