Specific USB Power Port Problems
When the USB ports are in use, the unit will monitor for the following
USB fault conditions on all the USB ports: thermal fault, low battery
voltage fault, overload and short circuit.
Problem Possible Solution
If a fault condition exists
in either of the USB
ports, the LCD will
display the USB fault
condition and the USB
power/fault indicators
shut off. In any of these
cases, the USB ports will
automatically shut down.
Should this occur:
A. Disconnect the USB-powered
device and press the power
button again to turn off the unit
immediately.
B. Allow the unit to cool down for
several minutes before attempting
to use the USB ports again.
C. If a fault occurs again, make sure
that the total draw of all USB
devices plugged into the USB
ports does not exceed 3.1A.
D. If an individual USB device is
within specifications and the fault
occurs, have the USB device
checked for malfunction and do
not continue to use it with these
USB ports.
Common Audio Problems
Problem Possible Solution
Buzzing Sound In
Audio Systems
Some inexpensive stereo systems and
boom boxes make a buzzing sound
when operated from the inverter,
because the power supply in the
electronic device does not properly filter
the modified sine wave produced by the
inverter. The only solution to this problem
is to use a sound system that has a
higher quality power supply.
Television
Interference
The inverter is shielded to minimize
interference with TV signals. However,
in some instances, some interference
may still be visible, especially when the
TV signal is weak. Try the following to
improve the picture:
1. Move the inverter as far away
as possible from the TV set, the
antenna, and the antenna cables.
Use a short AC extension cord, if
necessary.
2. Adjust the orientation of the antenna
cables, and the TV power cord to
minimize interference.
3. Make sure that the antenna feeding
the TV provides an adequate (snow-
free) signal and that high quality,
shielded antenna cable is used.
Care and Maintenance
STORAGE
1. Idealstoragetemperaturerangeis0-35°C (32-104°F).
2. Store and use the inverter 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.
12V DC VEHICLE ADAPTER FUSE REPLACEMENT
If the inverter is overloaded, and the blue LED is not lit, the internal
15 amp fuse may be blown. To replace the fuse:
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 15 amp fuse, if needed.
5. Carefully reassemble the fuse, end contact and flange. Do not
overtighten the flange (clockwise).
Troubleshooting
Specific AC Outlet Problems
When the 120V AC outlets are in use, the unit will monitor for the
following fault conditions: thermal fault, low and high battery voltage
fault, overload and short circuit (refer to the “Protective Features”
section).
Problem Possible Solution
If a fault condition exists
in either of the AC outlets,
the LCD will display the
fault condition and the AC
Outlets will automatically
shut down. Should this
occur:
A. Disconnect all appliances from
the unit and press the power
button again to turn off the unit
immediately.
B. Allow the unit to cool down for
several minutes.
C. Make sure the combined rating
of all appliance simultaneously
plugged into the inverter does
not exceed 140 watts continuous
when connected using the
supplied 12V DC adapter plug,
and 1000 watts continuous when
connected using the supplied
battery clips or direct hardwiring.
D. Make sure the appliance cord(s)
and plug(s) are not damaged.
E. Assure there is adequate
ventilation around the unit before
proceeding.
