The Audiovox D1788 is a portable entertainment system featuring a 7-inch LCD monitor and an integrated DVD player with a built-in battery. This versatile unit is designed for use in various settings, including hotels, offices, homes, or vehicles, offering a compact and easy-to-install solution for on-the-go entertainment.

Function Description

The primary function of the D1788 is to play DVDs, CDs, and MP3 discs, displaying video content on its 7-inch (16:9 Aspect Ratio) Liquid Crystal Display (LCD) monitor. It supports NTSC signal systems for video output and provides audio output with a frequency response of 20 Hz to 20 kHz. The unit is equipped with a semiconductor laser for disc reading.

Usage Features

Powering the Device:

The D1788 offers flexible powering options. For indoor use, it can be powered by plugging one end of the supplied AC to DC adapter into the DC 9-12V jack on the unit and the other end into a 100-240V AC power receptacle. For in-car use, a DC power adapter can be plugged into the unit's DC jack and then into the vehicle's DC power socket.

Built-in Battery:

The device includes a long-life Li-Polymer battery for portability. Before the first use, the battery requires a minimum of 8 hours of charging. Subsequent full recharges take approximately five hours and provide power for about 2 hours of playback. The battery charges when the AC to DC adapter is connected and the player is in "Power Off" mode; a red LED indicator will turn off once fully charged. The Li-Polymer battery technology ensures high storage capacity and low degradation, meaning it doesn't suffer from "Memory Effect" and can be recharged regardless of its current charge level.
