6QUATTRO MANUAL
BATTERY CHARGER
The pilot lamps on the battery charger should
always be ON during the charging operation. If they
are not, check to make sure you have turned off
both the transmitter and receiver.
Do not use the charger for equipment other than JR.
The charging plug polarity may not be the same and
equipment damage may 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 the warranty. If you are unsure of
compatibilities with your radio, seek expert advice
before doing anything to avoid possible damage.
During the charging operation, the charger’s
temperature is slightly elevated. This is normal.
Special note on J-line transmitter charge polarity:
8. CHARGING YOUR QUATTRO RADIO SYSTEM PRIOR TO INSTALLATION
Your Quattro Radio System is shipped from the
factory with both the transmitter and receiver
NiCad batteries in a discharged state. Before
attempting to install/operate your Quattro System,
it is important that the system be charged for
approximately 24 hours to ensure that both
transmitter and receiver packs are at peak capacity.
Under normal conditions, subsequent recharging of
your Quattro System will require only an overnight
charge (approximately 16 hours) to attain peak
charge capacity.
The charger supplied with this system is designed
to recharge your transmitter and receiver batter
packs at a rate of 50mAh.
The center pin of the charge receptacle on all J-line
brand radio systems is Negative polarity. Therefore,
the center pin on all J-line or JR chargers is
negative, not positive. Your J-line radio system’s
charge polarity is reversed from many other
manufacturers chargers. Beware of improper
polarity connections based on “color code” wire
leads as they DO NOT APPLY in this instance.
You must always be certain that the center pin on
any charger used with this system is wired for
negative polarity, otherwise damage will occur to
the charge circuit of the Quattro. The J-line warranty
does not cover any system that is damaged by
reverse polarity charging.
