For Fax inquires, please include a return Fax number for the reply. When calling or writing about your ADCOM product, be
sure to note and refer to its serial number as well as the date of purchase and the dealer from whom it was purchased.
In any communications to us, please include a daytime phone number where we may reach you. In the event the unit
must be returned to our factory for service, you will be instructed on the proper procedure when you call or write for a
Return Authorization.
UNDER NO CIRCUMSTANCES SHOULD YOUR UNIT BE SHIPPED TO OUR FACTORY WITHOUT PRIOR
AUTHORIZATION, OR PACKED IN OTHER THAN ITS ORIGINAL CARTON AND FILLERS.
If the original shipping carton and its fillers have been lost, discarded, or damaged, a duplicate carton may be obtained
from our Service Department for a nominal charge.
Always ship PREPAID VIA UNITED PARCEL SERVICE (UPS) OR OTHER APPROVED CARRIER. DO NOT SHIP VIA PARCEL POST,
since the packing was not designed to withstand rough Parcel Post handling.
CARING FOR YOUR GTP-860
Great care has been taken by ADCOM to ensure that your amplifier is as flawless in appearance as it is electronically.
The front panel is a heavy-gauge, high-grade aluminum extrusion carefully finished and anodized for durability. The
chassis, top cover and rear panel are heavy-gauge steel that has been powder coated and baked to ensure a lasting
finish. If the front panel, top or sides become dusty or fingerprinted, they can be cleaned with a soft lint-free cloth,
slightly dampened with a very mild detergent solution or glass cleaner.
Do not spray or pour liquids of any kind directly onto the GTP-860.
SERVICING
ADCOM has a Technical Service Department to answer questions pertinent to the installation and operation of your unit.
In the event of difficulty, please contact us for prompt advice. If your problem cannot be resolved through our combined
efforts, we may refer you to an authorized repair agency, or authorize return of the unit to our factory. To aid us in
directing you to a convenient service center, it would be helpful if you indicate which major city is accessible to your home.
