Battery Charging
Transmitter/Receiver
Note: It is imperative that you fully charge both the
transmitter and the receiver battery packs prior to
each trip to the field. 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 65mAh for the
transmitter and 150mAh for the receiver battery pack.
Transmitter Only
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 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 sure that the center pin of your JR transmitter is
always connected to the negative voltage for correct
polarity hookup.
Important: Please note that the charging polarity of
the transmitter and receiver are different.
Charger
The pilot lamps should always be on during the
charging operation. 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.
Equipment damage can result.
Do not use other manufacturers’ after-market
accessories that plug into the transmitter’s charging
jack if you are unsure of compatibility issues with your
radio. Seek expert advice to avoid possible damage.
During the charging operation, the charger’s
temperature is slightly elevated. This is normal.
