Adcom Protection Plan

Adcom offers the enclosed valuable Limited War- ranty. Please read the details on the Warranty Card carefully to understand the extent of the protection offered by the Warranty, its reasonable limitations, and what you should do in order to obtain its ben- efits. Be sure to verify that the serial number printed on the rear panel matches the serial number on the outer carton. If any number is altered or missing, you should notify us immediately in order to ensure that you have received a genuine Adcom product which has not been opened, mishandled, or tampered with in any way. Always retain your original sales receipt as a proof of purchase.

Product Care & Maintenance

Before your Adcom DVD player left our factory, it was carefully inspected for physical imperfections and tested for all electrical parameters as a routine part of Adcom’s systematic quality control. This, along with full operational and mechanical testing, should ensure a product flawless in both appearance and performance.

After you have unpacked the GDV-870, inspect it for physical damage. Save the shipping carton and all packing material as they are intended to reduce the possibility of transportation damage should the unit ever need to be shipped again.

In the unlikely event damage has occurred, notify your dealer immediately and request the name of the carrier so a written claim to cover shipping damages can be initiated. The right to a claim against a public carrier can be forfeited if the carrier is not notified promptly in writing and if the shipping carton and packing materials are not available for inspection by the carrier. Save all packing materials until the claim has been settled.

A Special Note on “Hum”

If there is a low-volume “hum” audible throughout your speakers, even with the main volume turned all the way down, you have a common phenomenon known as a “ground loop.” Generally, the cause of a ground loop is the CableTV incoming signal line.

To determine if your cable system is the contributing factor, disconnect the CableTV incoming signal line (round, 75Ω) at the wall, or the first component the cable is connected to (e.g. the cable box or VCR). If the hum is no longer present, you must insert a “75Ω ground loop isolator” before reconnecting the line. Check with your Adcom dealer to obtain one.

System Reset

In rare cases the GDV-870 internal processor may freeze or lock-up causing abnormal operation. This is common to all micro-processor controlled devices when the unit is subject to excessive static discharge, AC line noise, or power spikes. In most cases it is easy to solve this problem by simply turning off the GDV-870 with the rear power switch for about five minutes. After waiting, reconnect the power cord and turn the unit on. If the unit functions normally, no further action is needed.

If the unit still does not operate properly, it may be necessary to manually reset the processor; see “Use Default Settings” on page 24.

If the manual reset does not solve the problem, con- tact your authorized Adcom dealer, an authorized Adcom service center or contact Adcom’s service department directly for further advice.
