1. INTRODUCTION Your new Audiovox ADC700 inverter is one in a series of the most advanced DC to AC inverters available today. With proper care and appropriate usage, it will give you years of dependable service in your car, truck, RV, boat or even airplane.
2. HOW YOUR AUDIOVOX ADC700 INVERTER WORKS The ADC700 inverter is an electronic device that converts low voltage DC (direct current) electricity from a battery or other power source to standard 115 volt AC (alternating current) household power. In designing the ADC700, Audiovox has incorporated design techniques previously employed in computer power supplies. The result of these design innovations is a smaller, lighter and easier-to-use power inverter.
Figure 1. Audiovox ADC700 Inverter Operation ADC700 Output Waveform The AC output waveform of the ADC700 is known as a “quasi-sine wave” or a “modified sine wave”. It is a stepped waveform that is designed to have characteristics similar to the sine wave shape of utility power. This type of waveform is suitable for most AC loads, including linear and switching power supplies used in electronic equipment, transformers, and motors.

INSTALLATI0N Power Source Requirements The power source must provide between 11 and 15 volts DC and must be able to supply the necessary current to operate the load. The power source may be a battery or a well-regulated DC power supply. To obtain a rough estimate of the current (in amperes) the power source must deliver; simply divide the power consumption of the load (in watts) by 10.
CONNECTION TO POWER SOURCE The ADC700 comes with positive and negative wires and clamps (Red = +, Black = -) which are to be connected directly to the vehicle battery. CAUTION: Reverse polarity connection will result in damage to the Inverter. If the inverter is connected to the incorrect polarity, the fuse will be blown. If the unit does not function after replacement of the fuse, the unit must be returned to Audiovox for repair. Repair expenses for this type of damage are not covered by your warranty.
DO NOT CONNECT TO AC DISTRIBUTION WIRING The ADC700 is engineered to be connected directly to standard electrical and electronic equipment in the manner described above. Do not connect the Power Inverter to household or RV AC distribution wiring. Do not connect the Power Inverter to any AC load circuit in which the neutral conductor is connected to ground (earth) or to the negative of the DC (battery) source.
PLACEMENT OF THE ADC700 For best operating results, the inverter should be placed on a flat surface, such as a vehicle seat or floor. A power cord measuring 3 feet (1.0 meter) has been provided for easy positioning of the inverter. ADC700 should only be used in locations that meet the following criteria: DRY: Do not allow water or other liquids to come into contact with the ADC700 inverter. COOL: Ambient air temperature should be between -20° C and 40° C (ideally between 15° C and 25° C (60 - 80° F).
4. OPERATING TIPS Rated versus Actual Current Draw of Equipment Most electrical tools, appliances and audio/video equipment have labels that indicate the power consumption in amps or watts. Be sure that the power consumption of the item you wish to operate is rated at 700 watts or less. (If the power consumption is rated in amps, simply multiply by the AC volts (115) to determine the wattage). The inverter has overload protection, so it is safe to try to operate equipment rated at 700 watts or less.
BATTERY OPERATING TIME With a typical vehicle battery, a minimum operating time of 2 to 3 hours can be expected. In most instances, 5 to 10 hours of operating time is achievable. However, Audiovox recommends that the operator start the vehicle every 2 to 3 hours to recharge the battery system. This will guard against any unexpected shutdowns of the equipment and will ensure that there is always sufficient battery capacity to start the vehicle’s engine.
Overload Protection - The inverter will automatically shut down when the continuous draw exceeds 700 watts. Over Temperature Protection - When the temperature sensor inside the ADC700 reaches 150°F, the unit will automatically shut down. Allow the unit to cool for at least 15 minutes before restarting after a heat-related shutdown. Unplug unit while cooling. CAUTION: Low Battery Alarm An alarm will sound when the voltage from the battery drops to 11.5 volts.
Television Interference The Audiovox ADC700 is shielded to minimize interference with TV signals. However, in some instances, some interference may still be visible, particularly with weak TV signals. Try the following corrective measures: Position the ADC700 as far as possible from the television, the antenna and the antenna cables. Use an extension cable, if necessary. Adjust the orientation of the ADC700, the antennae cables and the TV power cord to minimize interference.
PROBLEM: LACK OF POWER OUTPUT (Cont) Inverter in thermal shutdown condition. Allow inverter to cool down. Ensure there is adequate ventilation around unit. Ensure that load is no more than 700 watts for continuous operation. Inverter fuse blown. Replace inverter is connected fuse. Be sure the to a power source with correct voltage and polarity. PROBLEM: LOW OUTPUT VOLTAGE Possible Causes Suggested Solution Using average reading voltmeter. Use true RMS reading meter. Inverter is overloaded.
PROBLEM: LOW BATTERY ALARM SOUNDS CONTINUOUSLY Possible Causes Suggested Solution Poor battery condition. Replace battery Inadequate power or excessive voltage Clean battery terminals and replace if necessary.
