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 receiver 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 GFR-700, 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 re- ceiver ever need to be shipped again. In the unlikely event damage has occurred, notify your dealer im- mediately and request the name of the carrier so a written claim to cover shipping damages can be initi- ated. 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 mate- rials 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 GFR-700 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 GFR-700 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.

In the event that the unit still does not operate prop- erly, it may be necessary to manually reset the pro- cessor. Note, however, that when the processor is reset you will lose all settings including digital au- dio assignments, surround mode settings, speaker configurations, tuner presets and any other memory items. For this reason we strongly recommend that you record these settings so that it is easy to restore them after resetting the processor. To reset the unit to factory default settings you will need to enter the discrete remote control command. Please refer back to the discrete remote control commands table. The command name is “Factory Defaults”, the IR code is 86h. This should reset the system.

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.
