XP662 MANUAL Introduction

CHAPTER 4: BATTERY CHARGING

•

Introduction

The pilot lamps 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 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.

CHARGER4.2

It is imperative that you fully charge both the

transmitter and the receiver battery packs prior to

each day of flying. For the initial charge, leave the

charger and batteries hooked up for 20–24 hours in

order to fully charge both battery packs to peak

capacity. For subsequent charges, leave the charger

and batteries hooked up overnight (approximately

16 hours).

The charger supplied with this system is designed to

recharge your transmitter battery at a rate of 50mA.

The receiver battery pack will charge at 50mA for the

600mAh airplane battery pack and at 150mA for the

1000mAh helicopter 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 any other manufacturers’ chargers and radio

systems. Beware of improper connections based on

“color code” wire leads, as they do not apply in

this instance. You must make certain that the

center pin of your JR transmitter is always connected

to the negative voltage for correct polarity hookup.
