CHAPTER 4: BATTERY CHARGING
TRANSMITTER/RECEIVER
4.1
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 do, any
damage that results will not be covered by
warranty. 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.
