1. PRECAUTIONS

1. The DVH943 can easily be damaged by moisture, high temperatures or high humidity. Keep the inside of the car clean and well ventilated. 2. Never subject the DVH943 to strong shocks or open its case. Doing so may result in damage. 3. Use a soft, dry cloth to wipe dirt off the DVH943. Never use a hard cloth or thinner, alcohol, etc. For tough dirt, apply some cold or lukewarm water to a soft cloth and wipe off the dirt gently. 4. When the main unit is switched to the traffic announcement or PTY interrupt reception while using the DVH943, the effect from DVH943 doesnt work. 5. Some tracks may sound distored when adjustment; this is normal and not a cause for concern.

CAUTION

CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE MANUFACTURER FOR COMPLIANCE COULD VOID THE USERS AUTHORITY TO OPERATE THE EQUIPMENT.

Dolby Pro Logic II

Using the newest in digital matrix technology, Dolby Pro Logic II is a matrix decoder technology which further improves earlier Dolby Pro Logic. This new technology produces superb 5.1ch sound even with CDs and other stereo sources. The surround channel is converted to full-band (20 Hz-20 kHz) stereo, thus allowing stereo sources to be enjoyed with the impact of 5.1ch sound. Four modes can be set in accordance with the playback source, including MUSIC mode, MATRIX mode, MOVIE mode, and VIRTUAL mode. Dolby Digital is a totally discrete digital 5.1 channel format. Signals for the front 3 channels, 2 surround channels, and the low-frequency 0.1 channel are recorded discretely, so no crosstalk occurs between channels, and the sense of placement and depth of the sounds is reproduced faithfully. Manufactured under license from Dolby Laboratories. Dolby, Pro Logic and double-D symbol are trademarks of Dolby Laboratories.
INFORMATION FOR USERS: CHANGES OR MODIFICATIONS TO THIS PRODUCT NOT APPROVED BY THE MANUFACTURER WILL VOID THE WARRANTY.

7. INSTALLATION

Throughout the process of wiring this unit, disconnect the negative () terminal of your automobiles battery, and leave it disconnected until completely finished. Handling wires while the terminal is connected could result in dangero electrical shock or injury if an scccidental short circuit shoud occur.

Installation Precautions

CAUTION! Install correctly, using only the screws supplied as accessories. Using other screws may result in damage or injury.

Case Damage

8 mm max. CeNET Cable To connect a CeNET cable, hold it with the connector facing as shown, and insert securely. When disconnecting a CeNET cable, grasp the slide cap and squeeze gently. Optical Digital Cable Insert the black connector securely into the digital signal input connector until it locks. The cable clip can be used to secure up to two optical digital cables. When disconnecting a optical digital cable, squeeze the tabs at the right and left sides of the connector, and pull gently. Note: The optical digital cable should not be bent with a gentle arc radius of 1.5 cm or less. If it is bent sharper than this, the performance of the cable will be greatly reduced and the cable may be damaged. RCA Pin Cable When connecting an RCA pin cable, be sure to confirm the source of the connection first.
