Operating instructions

The power/fault LED indicator lights solid when the

converter is properly connected to a functioning DC

power source. The AC and USB outlets are ready to

use. (If the power/fault LED indicator flashes, refer to the

Troubleshooting Section of this Instruction Manual.)

CAUTION: TO REDUCE THE RISK OF PROPERTY

DAMAGE:

Always connect the converter to the 12 volt DC power

source before plugging any devices into the unit.

The standard Australian 240Vac AC and USB outlets allow

simultaneous operation of multiple devices. Simply plug the

240VAC appliance into the converter's AC outlet and/or plug

the USB-powered device into the converter's USB charging

port and operate normally.

Notes: Ensure that the wattage of all equipment

simultaneously plugged into the converter does not exceed

500 watts continuous.

If the converter does not work when using the vehicle

accessory outlet, make sure the ignition/accessory switch is

actually powering the accessory outlet.

Some vehicles require the ignition switch to be turned on.

The converter will not operate appliances and equipment

that generate heat, such as hair dryers, electric blankets,

microwave ovens and toasters.

This converter's USB Charging Port does not support data

communication. It only provides 5 volts/500mA DC power to

an external USB powered device.

Remember to turn the unit off and disconnect from any

power source when it is not in use.

Care and maintenance

Storage

1. Ideal storage temperature range is 0-40°C (32-104°F).

2. Store and use the converter in a cool, dry place with

adequate ventilation for all-around air circulation.

3. Avoid locations that are exposed to heating units,

radiators, direct sunlight, or excessive humidity or

dampness.

Fuse replacement (in vehicle accessory outlet plug)

If the converter is overloaded, and the green LED is not lit,

the internal 12 amp fuse may be blown.

1. Unscrew the flange of the plug (counterclockwise).

2. Remove the end contact, flange and fuse.

3. Inspect the fuse to see if it is good or blown.

4. Replace with a new 12 amp fuse, if needed.

5. Carefully reassemble the fuse, end contact and flange.

Do not overtighten the flange (clockwise).

Troubleshooting

Common audio problems

Buzzing sound in audio systems

Some inexpensive stereo systems and boom boxes make a

buzzing sound when operated from the converter, because

the power supply in the electronic device does not properly

filter the modified sine wave produced by the converter. The

only solution to this problem is to use a sound system that

has a higher quality power supply.

Television interference

The converter is shielded to minimize interference with TV

signals. However, in some instances, some interference

may still occur, particularly where TV signals are weak. Try

the following corrective measures:

•

Place the converter as far as possible from the television,

the antenna and the antenna cables. Use an extension

cable, if necessary.

•

Readjust the orientation of the converter, the antenna

cables and the TV power cord to minimize interference.

•

Make sure the antenna feeding the television provides

an adequate ("snow free") signal and that high quality,

shielded antenna cable is used.
