D. Connecting the Portables
Before connecting to your portable double check on :
1. The output voltage as display in the middle window of LCD matches your portable's voltage.
2. Make sure the polarity of is correct.
3. Any mis-match of the above 2 important points will or may damage your portable.
E. Using the USB power output
The USB output is made to the USB power standard of 5VDC and 0.6A .
You can power up or charge your portables such as I-Pod , MP3 which have USB power connectors for getting
dc power from PC (Personal Computer).
Select from the accessory C the correct phone charge plug to charge your cell phone.
REMARKS:
NOT ALL THE CELL PHONE CAN BE CHARGED BY THE USB.
NEW MODELS REQUIRE HIGHER VOLTAGE THAN THE 5V USB .
F. Changing the Backlight Color of LCD
1. First disconnect power to adapter by removing either the cigarette plug or DC-IN
2. Press and hold the preset button
3. When the LCD is lit up again, release the preset button
4. Then quick press on the Preset Button will change the backlight color.
5. When desired color is found, disconnect power to adapter as in 1.

Included Accessories:
(A) Dc input cable (1.5M) with cigarette plug.
(B) Dc output cable (1.5M) with 7 pieces of common plugs (polarity reversible)
(C) One spare 5Amp fuse for cigarette plug.
Safeguarding your battery
This unique function protects your car battery from over-discharged by current draining portables.
You will not be left stranded with a flat battery.
The Micro-Processor keeps on checking the battery voltage and charge state of your car (12V system) or
your truck (24V system).
When it detects your battery drops to a critically low level, the LCD backlight first changes to flashing red
and warning buzzer will sound and all outputs (3A DC output and USB) are cut off.
Protections
A. Short circuit & overload protections
When the DC output or the USB is shorted circuited or draws more than the maximum current the current
limiting protection will be activated to limit the output current hence the adapter.
B. Over voltage (output) Protection and Buzzer Warning
This is to protect voltage sensitive expensive portables from high DC output voltage.
When the actual output voltage is about 1volt higher than the preset value for DC output
The LCD backlight will turn Red and buzzer alarm is on, followed by cut off of both main output and USB
output.
C. Thermal fuse protection
There is a 5Amp thermal fuse in the cigarette plug for over current at the input.
and at the same time reconnect power to adapter.
