Operating AC Appliance
1. Check battery status to ensure the battery is fully charged.
2. Open the AC Outlet cover.
3. Turn the AC socket ON though press the switch for AC and USB.
4. Plug the AC appliance into AC outlets.
5. Turn the AC appliance ON.
6. Recharge the PowerTunes immediately after use and every 3 months
Low Battery Alarm
An audible alarm will begin to beep intermittently when the battery reaches 11.0V DC and AC / USB
is ON. The AC/USB of PowerTunes must be turned OFF manually after all AC and DC loads are
removed. If after a while the voice guided warning is ignored and a manual turn-off is not performed
the unit will do a complete shutdown automatically.
Overload and Over-Temperature Protection
In the event of an overload (>350W) or overheating, the PowerTunes automatically shuts down
power to the AC outlets and audible alarm will start. Please remove the Power and turn off the
AC/USB to cool down the unit.
High Surge Appliance
The wattage rating of AC appliance is the average power used by the appliance. Appliances such
as televisions, computer monitors and appliances with motors consume much more power than
their average rating when they are first switched on.
Although PowerTunes can supply momentary surge power up to 700W, some appliances may
exceed the capabilities of the Powertunes
and trigger the inverter’s safety overload shutdown
circuit.
Sensitive Electronics
The output of the Powertunes inverter is not a true sine wave. Some equipment may be damaged
by the inverter’s modified sine wave output.
Some appliance, including the types listed below, may be damaged if they are connected to the
inverter.
DO NOT plug in battery chargers for cordless power tools if the charger carries a warning that
dangerous voltages are present at the battery terminals.
Electronics that modulate RF (radio frequency) signals on the AC line will not work and may be
damaged.
Speed controllers found in some fans, power tools, kitchen appliance, and other loads may be
damaged.
Some chargers for small rechargeable batteries can be damaged.
Metal halide arc (MHI) lights can be damaged.
