an equilateral triangle warns a user of the device
that it is necessary to refer to the instruction manual
and its warnings for proper operation of the unit.
Do not place this unit on an unstable cart, stand, tripod,
bracket, or table. The unit may fall, causing serious
injury to a child or adult, and serious damage to the
unit. Use only with a cart, stand, tripod, bracket, or
table recommended by the manufacturer or sold with
the unit. Any mounting of the device should follow the
manufacturer’s instructions, and should use a mounting
accessory recommended by the manufacturer.
Read all the safety and operating instructions before connecting or using
this unit.
Retain this notice and the owner’s manual for future reference.
All warnings on the unit and in its operating instructions should be adhered to.

CAUTION
TO PREVENT ELECTRIC SHOCK DO NOT USE THIS POLARIZED PLUG WITH
AN EXTENSION CORD, RECEPTACLE OR OTHER OUTLET UNLESS THE
BLADES CAN BE FULLY INSERTED TO PREVENT BLADE EXPOSURE.
CAUTION POWER LINES
Any outdoor antenna must be located away from all power lines.
OUTDOOR ANTENNA GROUNDING
If an outside antenna is connected to your tuner or tuner/preamplier,
be sure the antenna system is grounded so as to provide some protection
against voltage surges and built-up static charges. Section 810 of the
National Electrical Code, ANSI/NFPA No. 701984, provides information
with respect to proper grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit, size of
grounding conductors, location of antenna discharge unit, connection to
grounding electrodes, and requirements for the grounding electrode.
a. Use No.10 AWG (5.3 mm2) copper, No.8 AWG (8.4 mm2) aluminum, No.17
AWG (1.0 mm2) copper clad steel or bronze wire, or larger, as a ground
wire.
b. Secure antenna lead-in and ground wires to house with stand-off
insulators spaced from 46 feet (1.221.83 m) apart.
c. Mount antenna discharge unit as close as possible to where lead-in enters
house.
d. Use jumper wire not smaller than No.6 AWG (13.3 mm2) copper, or the
equivalent, when a separate antenna grounding electrode is used. See NEC
Section 810-21 (j).
EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE
INSTRUCTIONS CONTAINED IN ARTICLE 810. RADIO AND TELEVISION EQUIPMENT.
The unit should be installed so that its location or position does not interfere
with its proper ventilation. For example, it should not be situated on a
bed, sofa, rug, or similar surface that may block the ventilation openings;
or placed in a built-in installation, such as bookcase or cabinet, that may
impede the ow of air through its ventilation openings.
The unit should be situated away from heat sources such as radiators, heat
registers, stoves, or other devices (including ampliers) that produce heat.
The unit should be connected to a power supply outlet only of the voltage
and frequency marked on its rear panel.
The power supply cord should be routed so that it is not likely to be walked
on or pinched, especially near the plug, convenience receptacles, or where
the cord exits from the unit.
Clean unit only as recommended in its instruction manual.
The power supply cord of the unit should be unplugged from the wall outlet
when it is to be unused for a long period of time.
Care should be taken so that objects do not fall, and liquids are not spilled,
into the enclosure through any openings.
This unit should be serviced by qualied service personnel when:
A. The power cord or the plug has been damaged; or
B. Objects have fallen, or liquid has been spilled, into the unit; or
C. The unit has been exposed to rain, or liquids of any kind; or
D. The unit does not appear to operate normally, or exhibits a marked
change in performance; or
E. The device has been dropped, or the enclosure damaged.
DO NOT ATTEMPT SERVICING OF THIS UNIT YOURSELF.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
This reminder is provided to call the CATV system installer’s attention to
NOTE TO CATV SYSTEM INSTALLER
Article 82022 of the National Electrical Code that provides guidelines for
proper grounding and, in particular, species that the cable ground shall
be connected to the grounding system of the building, as close to the
point of cable entry as practical.
Congratulations on your decision
clearance
5"
to purchase the GTP-602 tuner/
preamplifier. Your new ADCOM component was designed to deliver incredible sound and years of reliable performance. Audition the GTP-602 paired
with an ADCOM power amp and DVD
player and you will experience what
high performance is all about. To realize the full potential of your GTP-602,
and before making any connections
to it, please read these operating and
installation instructions thoroughly.
Key Features
• RDS tuner
• Phono input stage
• RS 232 control
• Torriodial power transformer
Unpacking the GTP-602
Before your new ADCOM tuner-preamplifier 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 GTP602, 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 preamplifier
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.
Placing the GTP-602
Although the GTP-602 does not generate much heat, it is good practice
to provide adequate ventilation for
the unit. Therefore, the GTP-602
should be kept away from external
sources of heat such as radiators and
hot-air ducts.
We recommend that you exercise care
when placing components on top of the
GTP-602. If you are placing a heat producing component (such as an amplifier) on top of or below the GTP-602, it
is recommended that you allow at least
three (3) inches vertical spacing for
proper airflow.
We also recommend that you leave five
(5) inches of space behind the unit for
additional airflow and to allow space
for interconnects to hang freely.
If you observe these recommendations, the GTP-602 will perform reliably
in any reasonable environment. You
should also pay attention to such normal considerations as protection from
excessive dust and moisture.
The optimal performance of your new
GTP-602 will ultimately depend on the
care with which you make the connections between the amplifier, preamplifier and loudspeakers. All input and
output signal connections should be
made only with high quality, low-loss,
low capacitance cables. For recommendations of the type and quality of
interconnections that are best for your
applications, consult with your ADCOM
retailer.
Safety Information
There are no user serviceable parts
inside. Refer all servicing to qualied
service personnel.
The unit must be connected to a power
supply only of the type and voltage
specied on the rear panel. Connect
the component to the power outlet only
with the supplied power supply cable or
an exact equivalent. Do not modify the
supplied cable. Do not defeat grounding
and/or polarization provisions. The
cable should be connected to a 3-pin
polarized wall outlet, matching the
wide blade of the plug to the wide slot
of the receptacle. Do not use extension
cords. Do not route the power cord
where it will be crushed, pinched,
bent, exposed to heat, or damaged in
any way. Pay particular attention to
the power cord at the plug and where
it exits the back of the unit. The power
cord should be unplugged from the wall
outlet if the unit is to be left unused
for a long period of time. Immediately
stop using the component and have
it inspected and/or serviced by a
qualied service agency if:
• the power supply cord or plug has
been damaged;
• objects have fallen or liquid has
been spilled into the unit;
• the unit has been exposed to rain;
• the unit shows signs of improper
operation; or
• the unit has been dropped or
damaged in any way.
