Using the Inverter to Operate a TV or Audio Appliance
This inverter is shielded and filtered to minimize signal interference. Despite this, some interference may occur with your
television picture, especially with weak signals. Below are some suggestions to try and improve reception.
1. Make sure the television antenna produces a clear signal under normal operating conditions (i.e., at home plugged
into a standard 110 AC wall outlet). Also, ensure that the antenna cable is adequately shielded and of good quality.
2. Try altering the positions of the inverter, antenna cables, and television power cord.
3. Add an extension cord from the inverter to the TV so as to isolate it, its power cord and antenna cables from the 12
volt power source.
4. Try coiling the television power cord and the input cables running from the 12 volt power source to the inverter.
5. Affix one or several "Ferrite Data Line Filters" to the television power cord. Ferrite
Data Line Filters can be purchased at most electronic supply stores.
6. Try grounding the inverter with an 18 AWG (minimum), using as short a length as possible.
You may hear a "buzzing" sound being emitted from inexpensive sound systems when operated with the inverter. This is
due to ineffective filters in the sound system. Unfortunately, this problem can only be resolved by purchasing a sound
system with a higher quality power supply.
If the Fuse Blows?
Your power inverter is fitted with a 25 amp fuse, which should not have to be replaced under normal operating
circumstances. A blown fuse is usually caused by reverse polarity or a short circuit within the appliance or equipment
being operated.
If the fuse does blow:
1. Disconnect the appliance or equipment immediately.
2. Find the source of the problem, and repair it.
3. Install the new fuse.
The fuse can be found in the 12V DC barrel connecter.
Attention:
Do not install a fuse higher than 25 amps, as this may damage the inverter.
Make sure to correct the cause of the blown fuse before using the 200 Watt again.
Power Source
Your average automobile battery will provide an ample power supply to the inverter for 30 to 60 minutes even when the
engine is off. The actual length of time the inverter will function for depends on:
The age and condition of the battery
The power demand from the equipment being operated with the inverter
If you decide to use the inverter while the engine is off, we recommend:
1. Turn OFF the device plugged into the inverter before starting the engine.
2. Start the engine every hour and let it run for approximately 10 minutes to recharge the battery.
Attention:
Although it is not necessary to disconnect the inverter when turning over the engine, it may briefly cease to operate as
the battery voltage decreases.
When the inverter is not supplying power, it draws very low amperage from the battery. The inverter may be left
connected to the battery for up to three hours.
It is recommended that the inverter always be disconnected when not in use.

How Do Power Inverters Work?
There are two stages involved in transforming 12 volt DC (or battery) power into 110 volt AC power (household current):
STAGE 1:
The power inverter uses a DC to DC transformer to increase the 12 volt DC input voltage from the power source to 125
volts DC using advanced MOSFET transistors in a full bridge configuration.
STAGE 2:
