Caring for your GTP-830

ADCOM has taken great care to ensure your GTP-
830 is as flawless in appearance as it is electronical-
ly. The front panel is a heavy gauge, high-grade alu-
minum extrusion carefully finished and anodized
for durability. The chassis, top cover, and rear pan-
els are powder-coated heavy gauge steel that have
been baked to ensure a lasting, durable finish. If the
front panel, top or sides become dusty or finger
printed, they can be cleaned with a soft lint free
cloth, slightly dampened with a very mild detergent
solution or glass cleaner.

WARNING! Do not spray or pour liquids of any
kind on the GTP-830.

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. Please have
the following information readily at hand: the unit’s
model and serial numbers; and the dealer from
which it was purchased. If your problem cannot be
resolved through our combined efforts, we may
refer you to an authorized repair agency, or author-
ize 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
most accessible to your home.

UNDER NO CIRCUMSTANCES SHOULD YOUR
UNIT BE SHIPPED TO OUR FACTORY WITHOUT
PRIOR AUTHORIZATION, OR PACKED IN OTHER
THAN ITS ORIGINAL CARTON AND 
PACKAGING MATERIAL.

For Fax inquires, please include a return Fax or
voice telephone number for the reply. When calling
or writing about your GTP-830, be sure to note and
refer to its serial number, as well as the date of pur-
chase and the dealer from whom it was purchased.
In the event the unit must be returned to our factory
for service, you will be instructed on the proper pro-
cedure when you call or write for a Return
Authorization. For warranty coverage, a copy of the
original proof of purchase is required. If you have
no original copy, please contact your dealer to
obtain a duplicate copy.

If the original shipping carton and its fillers have
been lost, discarded, or damaged, a duplicate car-
ton may be obtained from our Parts 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 packaging was
not designed to withstand rough Parcel Post 
handling.

FREIGHT COLLECT SHIPMENTS CANNOT BE
ACCEPTED UNDER ANY CIRCUMSTANCES.
