USING THE LIGHT
There are 5 lighting modes:
• High (100% power)
• Normal (50% power)
• Energy saving (25% power)
• Emergency ash
• SOS
Press once to turn the light ON or OFF.
Press twice quickly, to change to the
next mode.
USING THE AC POWER OUTLETS
The DH139 is equipped with a 500W pure
sine wave inverter, which produces the
best power for all electronic devices and
appliances, without damage.
It is important to know the continuous
wattage of the device you plan to use with
the AC outlets. The unit must be used with
devices drawing 500 watts or less.
Devices such as fans or electric motors
require additional power to start (commonly
known as the “starting” or “peak” power).
The generator can supply a momentary
surge in wattage of as high as 2,500W
for less than 1/10 of a second; however
even devices rated less than the maximum
500 watts can exceed the inverter’s surge
capability and cause an automatic overload
shutdown.
Do not use the inverter with a product that
draws a higher wattage than the inverter
can provide, as this may cause erratic
operation.
CAUTION: Always run a test to establish
whether the inverter will operate a
particular piece of equipment or device.
In the event of a power overload (noted
with an audible alarm beeping every 3
seconds and a ashing Warning icon),
the inverter is designed to automatically
shut down. This safety feature prevents
damaging the inverter while testing devices
and equipment within the 500-watt range.
If powering more than one device, start one
device at a time to avoid a power surge and/
or inverter overload. The surge load of each
device should not exceed the inverter’s
Continuous Operation wattage rate.
You can use an extension cord from the
inverter to the device without signicantly
decreasing the power being generated by
the inverter. For best operating results,
the extension cord should be 16 AWG
(1.31 mm
2
) or larger and no longer than
50 feet.
WARNING!
RISK OF ELECTRIC SHOCK.
Incorrect operation of your inverter may
result in damage and personal injury. The
inverter output is 110V AC and can shock
or electrocute the same as any ordinary
household AC wall outlet.
NOTE: The maximum continuous load
is 500 watts. Do not use the AC outlets
with a product that draws more than
500 watts, as this may cause erratic
operation.
CAUTION:
• Do not connect an AC power source to
the 110V AC outlets.
• Do not connect the unit’s AC power cord
to its 110V AC outlets.
NOTE: Do not power an AC device while
charging the internal battery.
1. Connect your AC-powered devices or
small household appliances to one or
more of the unit’s two AC outlets.
NOTE: Make sure the device to be
powered is OFF before inserting the plug
into the AC power outlet.
2. Press the AC Output button. The
AC Output icon will show on the
display and the green AC power LED
lights, to conrm that the unit is on and
ready to provide AC power. The rotating
Discharging indicator will also show
on the display.
NOTE: Extended operation of an AC device
may result in excessive battery drain.
3. Recharge the unit when the battery
level is below 40%.
