WELCOME

Dear Fellow ADCOM Product Owner,

Welcome to the ADCOM family! For more than twenty years, ADCOM products have delivered
excellent performance and value for customers around the world. Our products are designed by
our experienced and demanding engineering team, built to the highest standards in our factory,
and sold and serviced through dealers, custom installers, and other retailers whose primary goal
is your complete satisfaction.

We know you are anxious to see and hear your new DVD player in action, but please take a few
minutes to read this owner’s manual before connecting the DVD player to your system. It is
particularly important that you connect your DVD player to your preamplifier while the ampli­fier and preamplifier are unplugged and your other equipment is turned off. This will protect
your equipment from potential short circuits that may occur during installation. In addition, it is
important that you allow for adequate ventilation around your DVD player and other equipment,
since excessive heat buildup can shorten the life of any electronic product, including the DVD
player. Once you have correctly connected your new DVD player to your other components, you
should be able to enjoy many trouble-free years of performance.

We conduct a thorough quality and performance test on each and every DVD player we build in
our factory prior to shipment. In the rare case of a defect that may occur after shipment, we
stand behind our DVD players with a two-year parts and labor warranty. To register for this war­ranty, please complete and mail the enclosed warranty card back to ADCOM. Also, please keep
a copy of your sales receipt with the owner’s manual so you may provide proof of eligibility for
the warranty should the need arise.

We know you will be very happy with the audio and video performance of your new DVD player. We
hope you will also consider other ADCOM products, such as our line of multichannel amplifiers and
preamplifiers. In addition, we design and manufacture complementary products such as surge sup­pressors and speaker selectors. Please visit our web site at www.adcom.com to learn more about
our complete line of stereo, home theater, and distributed audio/video products.

On behalf of all of us at ADCOM, I want to thank you for selecting our product for your home or

1.4 Input & Output

System Connections

Like the front panel, the GDV-850’s

rear panel is carefully arranged to

make hookup, configuration, and use

as simple as possible. However, the

GDV-850’s capabilities take some study

to use most effectively. We strongly

suggest that you read this section of

the manual before beginning to hook

up your player. You will save yourself

much time and effort if you carefully

think out what you expect from your

system, consider the components you

will use, where they’ll be placed,

and how you will want them to work

together. The notes in this section and

the connection diagrams that follow

will probably answer most of your

questions about interfacing the GDV-

850 into your system.

[11]

Region Code

The GDV-850 is configured for use in spe-

cific geographic locations. Geographic

regions around the world are assigned a

numeric code by the DVD forum which is

indicated on this icon. See section 7.0 of

this manual for more information.

[12]

Component Output

Use this output to connect the GDV-850

18

19 20 16

to a preamp that accepts component

video input or directly to your display. A

component video signal typically refers

to Y/Pb/Pr, which consists of three

75-ohm channels: one for luminance

information, and two for color.

Note: The 480P progressive scan output can only be used with

a digital television capable of displaying or converting 480P images.

[13]

Video Format Switch

With the GDV-850 you have the abil-

ity to switch between progressive-scan

(480p) and an interlaced (480i) video

signal. Use this switch to set the video

output format. When the progressive

output is selected the S-video and

composite outputs are disabled and the

progressive status indicator on the front

panel will illuminate.

[14]

S-video Output

S-video may also be referred to as

Y/C, the abbreviation for luminance/

chrominance. The S-video cable uses

a four-pin connector that is most com-

21

22 24

monly used with VCRs and DVD players.

S-video delivers a better picture than

composite connections and should be

used whenever possible unless you can

use component connections, which typi-

cally deliver better video than S-video.

[15]

Composite Output

Composite video is used in nearly all con-

sumer video devices. Both chrominance

and luminance signals are carried on the

same 75-ohm RCA cable. Chrominance is

carried in a 3.58-mHz (NTSC) sideband

and filtered out by the TV’s notch or

comb filter. Poor filtering can result in

dot crawl, hanging dots, or other im-

age artifacts. We recommend using this

output only when component or S-video

inputs are not available.

[16]

RS232 Input

Allows control of the GDV-850 via com-

puter or home automation system. A DB-9

| ADCOM GDV-850 Owner’s Manual8

cable is used to make the connection to

the GDV-850. Refer to section 2.3 for

more detail.

[17]

Analog Audio Output

Using the analog audio output allows

the internal DSP and DACs to decode

and convert the data from the disc to

analog signals. This output is used when

connecting the player to an analog stereo

preamp, and is necessary for use in many

distributed audio setups. This output

can also make use of analog direct

modes available on many preamplifiers

like ADCOM’s GTP-880.

[18]

5.1 Audio Output

To enjoy the high resolution playback

of multichannel DVD-Audio discs,

connect these six RCA jacks to the 5.1

analog inputs on your preamplifier or

receiver. Use six separate RCA cables

to make the connection to your pre-

amp. Due to copy protection issues,

the digital output may need to be off

during playback of DVD-Audio discs.

[19]

Digital Audio Output

Dolby Digital and DTS movie sound

tracks will be sent to your preampli-

fier via the digital audio output. Your

preamplifier must be able to decode

Dolby Digital and/or DTS digital sig-

nals. Otherwise, you will need to use

the GDV-850’s 5.1 analog outputs to

enjoy Dolby Digital and DTS sound.

[21]

IR Input

Use the IR input jack to connect an

external IR sensor to the GDV-850

when the unit is installed behind doors

or where it is not otherwise visible to

the remote.

[22]

Voltage Switch

Before plugging the unit in make sure

the voltage is set to your country’s

voltage configuration. The GDV-850

should be unplugged prior to flipping

this switch. If you are uncertain, please

have your installer or dealer verify

before proceeding.

[23]

Main AC Power Switch

Turns the current to the GDV-850 on

or off. Setting this button to the on

position supplies power to the unit,

enabling use of the standby power

button on the front panel. When the

main power switch is in the off posi-

tion, current is cut off to the unit.

[24]

IEC AC Input

Use to connect the supplied IEC re-

movable AC power cord (see page 2

for all warnings). Before proceeding,

please observe the following precau-

tions when connecting devices to your

new GDV-850.

Do not plug the power cord into your

GDV-850 until all other connections

have been made.

Caution: Before you plug the power cord

into an AC wall outlet, confirm that all

connections to the GDV-850 have been

made correctly.

Warning: Never disconnect the power cord

from the GDV-850 while the other end is

plugged into an AC outlet. Doing so may

cause an electric shock. Always connect

power by plugging into the AC outlet last

and disconnect by unplugging from the AC

outlet first.

[20]

12V DC Trigger

A trigger, if properly hooked-up, can prove

to be very convenient. Use the 12V DC

trigger in conjunction with your preamp

to turn the player on and off. The trigger

output from your preamp should go in to

the trigger input on the rear panel of the

GDV-850. A pass-through output jack is

provided to allow trigger control of ad-

ditional components in your system.

Insert the supplied power cord into

the AC input of the rear panel of the

Pressing this button turns the compo-

nent video output on. Note: This fea-

ture may be disabled in some regions

due to copy protection requirments.

[56] Digital Audio Out Off

Pressing this button turns the digital

[57] Digital Audio Out On

Pressing this button turns the digital

audio output on. The bitstream select-

ed on disc will be sent to preamp. Due

to copy protection requirments, when

playing a DVD-Audio with digital audio

out on, DVD-Audio will be truncated to

2.3 RS232 / IR Control

The Adcom GDV-850 can be controlled

via its serial RS-232 port. The serial port

can be connected to a PC or ‘dumb ter-

minal’ via a straight-through standard

9-pin serial port cable (MALE on one

end and FEMALE on the other end).

When using a PC, a terminal emulator pro-

gram, such as ProComm or the Windows

“Terminal” program can be used.

The communications parameters

should be set as follows: 9600 baud,

8 data bits, no parity, 1 stop bit and

Hardware Flow Control

Some of the commands can only be sent

to the Video Switch when it has been

‘unlocked’. This protects it against

inadvertent re-programming of its

serial number, and its default settings.

NOTE: all commands are CAPITAL let-

ters (ASCvII characters)...lower case

letters, or unrecognized commands

are ignored and a ‘?’ may be returned.

Data bytes associated with a command

can be upper or lower case letters and

numbers as appropriate.

Commands can only be entered after

the “>” prompt character is displayed.

The exception to this rule is that the

GDV-850 does not echo the command

prompt when first plugged in. After

the first command is received, prompts

are then automatically generated.

When a command has been received,

the command letter is echoed, fol-

lowed by a CR/LF, then “>” as a

prompt character.

If the command is one that returns

data (e.g. “S” – Status), then the data

is returned, followed by the echoed

command letter, and a CR/LF, then

“>” as a prompt character.

Command echoing can be turned on and

off by issuing the ”E” command (see

below). The GDV-850 echoes commands

by default on line cord power-up.

GDV-850 Setup Menu

4.1 Setup Overview

All congurations for the GDV-850 are

made in the setup menu. The setup

menu is displayed on the OSD and

accessed with the setup button on the

GRC-815 remote control. When the setup

button is pressed your source material,

if playing, is paused and a transparent

blue menu is displayed over the source

video. Please note that not all options

can be modied while source material

is active. Use the navigation keys on the

remote to navigate the setup menu, all

selections will be saved when you exit

setup. Pressing the setup button while in

the setup menu will exit the menu and

playback of your material will resume.

Changes can be made to the GDV-850 in

four main areas: general setup, speaker

setup, audio setup and preferences.

The TV display option allows the DVD
player video output to be congured
to match the size of your TV and your
viewing preferences. First, you need
to decide which type of TV you are
using. There are two different aspect
ratio TVs available today: standard (4:

3) and widescreen (16:9). If your TV is a
widescreen set, then you should select
the “widescreen” option. If your TV is
the standard 4:3 then you should select
either pan/scan or letter box. The let­ter box option will display black bars at
the top and bottom of the picture when
you are watching widescreen material.
If you don’t want to see the bars, then
you should select the pan/scan option.
When you are viewing widescreen mate­rial, the pan/scan options cuts off the
extreme left and right sides of the pic­ture, and lls your entire TV screen.

PIC Mode

frames per second. However, mate­rial originally shot on lm presents a
more difcult challenge since it was
shot at a frame rate of 24 frames per
second. When converted to video with
30 frames per second, this material may
show artifacts on fast motion scenes. An
advanced lm mode technique known
as reverse 3:2 pulldown improves the
picture with lm-based recordings.

Auto

The GDV-850 recognizes the picture
type based on ID codes embedded at
the start of the disc.
Film: This option activates the reverse
3:2 pulldown feature and is optimized
for lm source images. It should only be
used to force the progressive scanning
into lm mode.

Video

This option is optimized for video source
material and is used to force the progres­sive scanning into video mode.

4.2 General Setup

The General Setup page provides a
number of setup items relating to the
type of TV monitor, progressive scan­ning, and the appearance of On-Screen
Displays and the front panel display.

TV Display

This setting optimizes the Progressive
Scan mode. The setting is only in effect
if you are using an NTSC TV monitor.
It has no effect unless your monitor
accepts progressive scan video signals
and the GDV-850’s Progressive Scan fea­ture is activated. Progressive scanning
combines two interlaced (480i) elds
into a single progressive (480p) image
for display on digital monitors. When
source material was originally lmed
with video cameras, this is a relatively
straightforward digital conversion since
video is shot with a frame rate of 60
interlaced frames per second which
is then displayed at 30 progressive

Smart

The option may be best for discs with
mixed lm source and video source
material that cannot rely on an identi­fying code inserted at the beginning of
the disc. The GDV-850 senses the type
of recording for each scene and adjusts
the progressive scanning accordingly.

Super Smart

This option is the default setting and
usually provides the best performance.
In addition to activating lm or video
modes based on embedded codes, it
analyzes the video signal in real time
and uses motion adaptive interpolation
to optimize the display for rapidly moving
images or still images.

Angle Mark

You can choose whether or not to have
the unit display an angle icon in the
corner of the screen to inform you

19ADCOM GDV-850 Owner’s Manual |

21ADCOM GDV-850 Owner’s Manual |

when alternate angles are available
for a scene on a DVD Video disc.

On: Activates the display of the angle
icons, indicating that alternate angles
are available for the current scene.

Off: Turns off the display of angle icons.
Note: Even with Angle Mark off, the

angle icons appear when the ANGLE
button on the remote is pressed.

OSD Language

where you left off. Not all discs have
this feature.

Captions

Much like subtitles, captions are a tex­tual representation of the audio infor­mation in a video program. Captions
are usually intended for the hearing
impaired, and therefore include addi­tional text to identify the person speak­ing, off-screen sounds, and so on. The
options are on and off.

Scr (Screen) Saver

Grayscale in video is measured and
tracked on a scale of 0 (black) to 100
(white) IRE units. In NTSC video is tradi­tionally assigned the 7.5 IRE value as being
the black cutoff in a picture. Setting the
output to a 0 IRE signal will present richer,
deeper black tones in every image. The
options are IRE 0 and IRE 7.5.

Dimmer

The brightness of the front panel display
can be reduced to avoid distraction while
viewing in a darkened room. To adjust, use
the CURSOR buttons to select a setting
on the vertical slider control on the right
side of the menu screen. A setting of “1”
is the brightest setting. A setting of “7” is
the dimmest setting. The “OFF” setting
turns the front panel display off.

The language that the OSD displays may be
changed to your preference. The options
are English, Chinese and German.

Last Memo

Some DVDs have the ability to let you
watch part of a movie, take the disc
out, then re-start the movie from

After your player sits idle for a few min­utes the screen saver will be activated.
This option will help to increase the
life span of your monitor by preventing
images from burning into the display.
The options are on and off.

4.3 Speaker Setup

Speaker setup is an important step to

ensure you get the most out of your

system.

| ADCOM GDV-850 Owner’s Manual20

Output Mode

Subwoofer

about 1 foot per msec, so if your rear

speakers are three feet closer to the

listening spot than your fronts, add 3

msec. of delay.

Delays set in the DVD player will not be

duplicated by your preamp when the

signal goes out from your DVD player’s

digital output.

Setting the output mode determines

what outputs are active and how the

signals will be dispersed to your pre-

amp. The options are 5.1Ch Surround,

2Ch Stereo (ROLO), 2Ch Pro Logic (RTLT),

and 2Ch Virtual.

Center

You have the option to turn the center

channel on and off. If you select “Off”

the audio for the center channel will be

processed and dispersed between the

left and right front channels.

If you have a subwoofer select “On,”

otherwise select “Off.”

Cntr (Center) Delay

Sometimes your center channel cannot

be placed at a distance that is equal

to that of your left and right speaker.

For every foot of difference apply one

milli-second delay. The options are 5ms

to 1ms and off, in 1ms steps.

Rear Delay

Test Tone

Test tones are noise signals with a stan-

dardized level. An audible tone will play

in each of your speakers in a sequential

order, starting with left front. If any

channel has been deactivated in the

speaker setup, the test tone will pass

over this channel, without pausing the

test. If you do not hear a test tone

from a particular speaker, rst ensure

the physical connection is correct and

secure. Then check to see if the channel

is active in the setup.

Rear

You also have the option to turn the rear

channels on and off. If “off” is selected,

rear channel information will be sent to

the front speakers.

If your rear speakers are closer to your

listening spot than your fronts, adjust

this setting by adding delay to the

rear speakers. Add delay such that the

sound will arrive at the listening spot

from the front speakers and the rear

speakers simultaneously. Sound travels

Rear/Cntr Size

The speaker size is important to set in

relation to your setup. The front left and

right speakers are always set to large.

If needed, this setting can usually be

21ADCOM GDV-850 Owner’s Manual |

23ADCOM GDV-850 Owner’s Manual |

adjusted by your preamp. But you have

the option to change the size of rear

and center speaker in relation to your

conguration using the DVD player’s set-

tings. The options are large and small.

4.4 Audio Setup

S/PDIF: S/DIF stands for Sony/Philips

Digital Interface and is a standard

digital audio le transfer format. The

options are on and off.

Compress

LPCM (Linear PCM) Output

PCM is a digital stereo bitstream that

S/PDIF outputs. LPCM 48k down samples

96k or higher material to 48k. When 96k

is selected any material higher than 96k

will be downsampled. The options are

LPCM 48k and LPCM 96k.

4.5 Preferences

Video Out

This option allows you to select the

format of the video output. The RGB

option is a professional video format

that requires a hardware upgrade.

Audio

Compressing the signal is most com-

monly used in night mode listening,

when a lot of bass is not desirable. The

options are full to 1/8 and off in 1/8

steps. Compression only works with the

player’s analog outputs.

Pro Logic

Pro Logic is an algorithm created

by Dolby to enhance the playback

of a st e r e o signal. T he signal is

remixed to provide surround sound.

You can choose how and when the

DVD player enables this function.

The options are on, off and auto.

| ADCOM GDV-850 Owner’s Manual22

TV Type

Setting this preference determines the

format of video sent to your TV. The

options are: NTSC, PAL or by Title. For

best performance, your TV type should

match the format of the disc you are

watching. The United States uses

NTSC and much of Europe uses PAL.

Many DVDs provide additional tracks

with translations of the movie on

the disc. This option can be set from

the disc menu or as default from this

audio preference setting. The options

are English, French, Spanish, Chinese

and Japanese.

Subtitle

Subtitles are the lines of translated

dialogue at the bottom of a movie screen.

The language in which they are displayed

may be changed to your preference.

Th e option s are Engli sh, Fre nch,

Spanish, Chinese, Japanese and off.

Disc Menu

Set a disc’s menu to be displayed in

your preferred language. This setting

will automatically default the menu of

a disc to your desired language, if and

when this option is available on the disc,

without having to make this selection

each time you watch or listen to a new

disc. The options are English, French,

Spanish, Chinese and Japanese.

PG-13 or lower will play without a

password, but discs rated at Level 5 or

higher require a password. To adjust

the parental setting, use the navigation

buttons to select the desired restriction

level on the vertical slider control on the

5.1 Technology Overview

Disc Structure: Each type of disc

has its own organization, allowing you
to locate various portions of the pro­gram recorded on the disc. Depending
on the type of disc, these may be
called Titles, Groups, Chapters, or
Tracks:

DVD-Video:

A DVD-Video disc is comprised of
Titles and each title may be divided
into Chapters. For example, a DVD­Video disc may contain several mov­ies, each with its own Title number,
and each movie may be divided into
several Chapters. In a DVD-Video
karaoke disc, each song usually has
its own title number and does not
have Chapters.

DVD-Audio:

A DVD-Audio disc contains Groups,
with each group divided into Tracks.
Some DVD-Audio discs also contain a
Bonus Group that can only be played
back by entering a Key Number pass­word. Most DVD-Audio discs include
other information in addition to
audio, such as still pictures, movies
and text.

Audio CD:

An Audio CD, Video CD or SVCD simply
contains Tracks.

Progressive Scan: Most plasma

displays, LCD monitors and projectors
use a feature called progressive scan.

This displays all the line of a picture at
the same time, in one very fast burst,
which is in contrast to an aging process
called interlacing. Interlacing displays
every other line in two successive scans
of the monitor to complete the pic­ture. The GDV-850 has a switch on the
rear panel to select progressive scan.

Field-Adaptive Deinterlacing:

The field-adaptive deinterlacing is
an algorithm that enhances progres­sive scan video outputs by examining
individual pixels across three or more
fields of an image and selectively
interpolates regions of the picture to
form a progressive scan image that is
clear and artifact free.

Dolby: Dolby Digital can deliver

5.1-channel sound from DVD-Video
and DVD-ROM discs, laser discs, and
digital TV broadcasts, satellite trans­missions, and cable systems. It dif­fers from Dolby Surround (Pro Logic)
by providing two separate surround
channels for greater realism, and an
additional “.1” or “LFE” channel for
low-frequency (bass) special sound
effects. The LFE channel is some­times identified as the “subwoofer”
channel. While a subwoofer can be
helpful in reproducing low bass in
general, it is not necessary to have
one if one or more of the speakers in
the playback system have extended
bass response. Without a subwoofer,
the LFE channel’s bass effects can
be directed to those speakers with
extended bass. Furthermore, not all
multichannel soundtracks have the
“.1” channel; it is used primarily for
explosions, rumbles, and the like on
movie soundtracks, and is not present
on all programs.

DTS: This compressed digital data for-

mat is similar to Dolby Digital. DTS also
provides 5.1 channel surround channels
and is available on compact disc, DVD
and laser discs. Audio-only DTS discs
may be used with any CD, LD or DVD

player with a digital audio output.

DVD Audio: DVD-Audio is an exten-

sion of the highly popular DVD format,
distinguished by its capability for
delivering a new standard of quality
previously unavailable in packaged
audio media. A highly compelling fea­ture of DVD-Audio is its multichannel
audio capability, which is proving to be
optimal in an automotive environment.
DVD-Audio also includes a host of
value-added multimedia features not
previously available on compact disc.

MLP: Utilizing Meridian Lossless

Packing technology, DVD-Audio
discs can store up to six channels
of 24-bit/96 kHz audio, including a
separate low-frequency bass chan­nel. Compare that to two channels
of 16-bit/44.1 kHz sound from CDs.
For stereo buffs, a DVD-Audio disc
can alternatively hold two channels
of 24-bit/192 kHz audio, for stereo
recordings that exceed the quality
of any music audio format previously
available.

HDCD: High Definition Compatible

Digital, or HDCD, is a patented pro­cess for delivering 20 bits of musical
information on a standard CD. HDCD
overcomes the standard 16 bit limi­tation of the CD format by using a
sophisticated system to encode the
additional 4 bits onto the CD while
remaining completely compatible
with the CD format.

MP3 CD-R: The GDV-850 will play

MP3 files on a CD-R. A separate menu
will be displayed to navigate the disc.
MP3 format is a compression system
for audio tracks. This format helps
to reduce the number of bytes in a
song and create a file size that is
significantly smaller, allowing faster
transfer and the ability to store more
music on a disc. MP3 tracks, while
more compact, usually do not main­tain all the fidelity of CD audio.

battery installation, install new bat­teries, aim remote at unit.

No picture: check the video cable
connection and input setting on your
TV. Turn off the progressive scan
feature via the rear panel switch or
change the video output setting using
the remote control.

Picture is noisy: do not connect unit
directly to VCR (copyguard feature
may disrupt video signal), turn off
progressive scan feature or set its
mode to VIDEO.

Picture does not fill screen: Set TV
DISPLAY type correctly.

No sound: check the audio cable con­nection and input settings on preampli­fier. Make sure the SPDIF output is acti­vated when using a digital connection.

Garbled sound: Clean the disc surface.
Unit does not operate properly: To reset
the microprocessor, turn off the power,
unplug the power cord, and reconnect
the power cord. Following a sudden
temperature change (such as bringing
unit or discs inside from extreme cold),
allow several hours for possible conden­sation to clear.

5.3 Resolving Problems

Use the troubleshooting notes above
to solve common situations that don’t
require professional attention. If the
steps stated in possible solution do
not resolve your problem, then please
contact your ADCOM dealer or call the
ADCOM customer service department.
Any problems not covered here should
be brought to the attention of your
ADCOM dealer or ADCOM customer
service department.

A special note on “hum:” When 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.” A ground loop is
basically a difference in ground volt­ages between two or more components
which are connected electrically and
which creates multiple current paths
where there must only be one. This dif­ference in potentials creates a 60Hz low­level sound (approximately a low A),
that seems to “hum.”

It can be caused by adding new com­ponents to your system, but that does
not imply there is anything electrically
wrong with any new component. With
the advent of audio/video and home
theater systems, the problem has
become commonplace. Generally, the
cause is the Cable-TV incoming signal
line. This new incoming line may add
an additional ground at a different
potential to the AC line ground of your
other equipment (refer to note I and
2, to troubleshoot a hum problem).

Note 1: Cable TV systems can some­times contribute to ground loop prob­lems which cause “hum.” To determine
if your cable system is the contribut­ing factor, disconnect the Cable-TV
incoming signal line (round, 75Ω) at
the wall, or the first component the
cable is connected to (i.e. the cable
box, or VCR). If the hum is no lon­ger present, you must insert a “75Ω
ground loop isolator” before recon­necting the line. You should check
with your ADCOM dealer to obtain
one. If the “75Ω ground loop isolator”
works only partially or not at all, then
please read note 2 to complete the
troubleshooting procedure.

Note 2: Make sure that the power
amplifier is at least 6” from the GDV-

850. Usually putting another compo­nent between them is sufficient to
minimize the hum. If this does not
reduce the hum, turn the system off
and disconnect all Inputs from the
amplifier. If the hum still persists,
then your dealer or service center
must examine the unit/system. If the

hum disappears, try another set of
RCA cables. Connect one RCA cable at
a time to see if one specific cable is
responsible. If any or all cables cause
the hum to appear, then the unit
should be evaluated for proper opera­tion by your dealer or authorized ser­vice center. Please see our website or
call us for a list of authorized service
centers in your area.

5.4 System Reset

In rare cases the GDV-850 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 unplugging the
GDV-850 from its AC power source
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 properly, it may be neces­sary to manually reset the processor.
Note, however, that when the proces­sor is reset you will lose all settings
including surround mode settings,
and speaker configurations. 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, contact your authorized
ADCOM dealer, an authorized ADCOM
service center or contact ADCOM’s
service department directly for fur­ther advice.

5.5 Caring for your GDV-850

Great care has been taken by ADCOM to ensure that

your DVD player 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.

If you will not be using your home theater system for an

extended period of time, it is always a good idea to turn the

unit off using the power switch on the rear panel of the GDV-

850. This will prevent the automatic turn on circuits from

accidentally turning the system on during your absence.

6.0 Servicing

ADCOM has a technical service department to answer

questions pertinent to the installation and operation of your
