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.

no original copy, please contact your dealer to

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

SHIP VIA PARCEL POST, since the packaging was
not designed to withstand rough Parcel Post
