NOTE: Some inexpensive audio systems may experience a slight "buzzing" sound when operated
with a modified sine wave inverter. This is caused by deficient filters in the audio system. Pure sine
wave inverter can be used to reduce the buzzing noise.
Appliance Cautions:
DO NOT use an inverter to directly recharge nickel-cadmium batteries through appliances. Always
use the charger provided with that appliance.
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.
Some fluorescent lamps may not be fully compatible with an inverter. If the lamp appears to be too
bright, flickering or fails to light up, do not use the lamp with an inverter.
Some fans with synchronous motors may slightly increase in speed (RPM) and increase in noise
when powered by an inverter.
Certain chargers for small nickel-cadmium batteries can be damaged if plugged into a modified sine
wave inverter. In particular, two types of appliances are susceptible to modified sine wave:
• Small, battery-operated appliances such as flashlights, cordless razors and toothbrushes that
can be plugged directly into an AC receptacle to recharge.
• Certain battery chargers for battery packs that are used in some cordless hand-tools. Chargers
for these tools have a warning label stating that dangerous voltages are present at the battery
terminals.
DO NOT use modified sine wave inverters with the above two types of equipment.
The majority of portable appliances do not have this problem. Most portable appliances use separate
transformers or chargers that plug into AC receptacles to supply a low-voltage DC or AC output to
the appliance. If the appliance label states that the charger or adaptor produces a low-voltage DC or
AC output (30V or less), there should be no problem powering that charger or adaptor.
Safety Warning: 240V of electricity can be lethal. Improper use of a power inverter will result in
property damage, personal injury, or loss of life. Please read and follow carefully the instructions in
the instruction manual provided with every inverter for important safety considerations and
precautions.
