CHAPTER 4: BATTERY CHARGING
TRANSMITTER/RECEIVER
4A
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 50mAh for the transmitter and
120mAh 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.

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.
