Congratulations on your purchase of a new DOT-X Series with HARC
(Handheld Addressable Remote Control) option.
Thismanualhasbeenpreparedtoactasaguideintheoperationofyourunit
when the HarcPlus option is installed. Please read the following operating
instructions carefully before using your unit so that you are familiar with all
of its features and capabilities. All precautions and safety warnings should
be read and strictly observed.
SERVICE PACK CONTENTS
The service pack consists of the following:
• Storage box
• Remote Control
• 2 AAA Batteries
• Adjustment Stick
• This Manual
GETTING STARTED
Refer to the monitor manual for connecting power and signal to the
monitor.
For initial operation of multiple unit installations, apply power to only one
unit at a time, while changing the unit identification number (Unit ID) from
the factory set 01 to a sequence of unique numbers for each unit. (See
Changing Security Code and Unit Number.)
Unpack the remote control and install batteries.
The DOT-X SERIES with HARC responds to remote control inputs in a
manner similar to many other remote control devices including TVs,
VCRS etc. with two important differences. First, a security code is
required before access to any menus is allowed. Second, a unit selec-
tion number is required to select one unit from a group of several units,
allowing individual adjustments to individual units with one remote
control.
Until the security code and unit selection numbers are entered, the
monitor will not respond to the remote control.

The factory set security code is 5432. You can change this code at any
time. Refer to a later section of this manual titled CHANGING SECU-
RITY CODE AND UNIT NUMBER. At this point key in the security code
5432. As each number is pressed, an x will appear after the KEY IN
SECURITY CODE: line. If you miss-key a number the x’s will disappear
allowing you another chance to enter the code. When the correct code
is entered, press the ENTER key.
The following on screen display (OSD) will appear.
TO ACTIVATE THIS SET KEY IN 01
KEY IN SET #:
All units are shipped from the factory programmed as unit # 01. For
multiple unit installations, you will want to change the unit number of all
but one unit to other numbers. Typically the units are numbered in
sequence from 01 upward. The DOT-X SERIES HARC will accept unit
numbers up to 99. (If you need more than 99, consult the factory for a
special program.) At this point, key in 01, the numbers will appear after
the colon. If you miss-key the number, simply key in the desired num-
ber, the new number will replace the miss-keyed number. When you are
satisfied with the number, press the ENTER key.

press PREV. CH TO DE-SELECT UNIT
At this point, you can use the remote to control all available functions of
the unit. Please refer to later sections of this manual for details on using
those controls.
In a multi-unit installation, units that are not selected may not clear their
screen after the desired unit is selected. Security or unit-id screens can
be cleared on these units by pressing the MUTE (or M) key on the
remote and pointing the remote at the non-selected unit(s).
If this is a multiple unit (monitor) installation, this is a good time to
change the unit number so that each unit will have a unique number
when all units are powered up. Refer to the section of this manual titled
CHANGING SECURITY CODE AND UNIT NUMBER for the procedure
to change the unit number. If you desire, you can change the security
code at the same time.
When you are done using the controls, press the PREV. CH. key.
This de-selects the unit, returning security and unit selection to
their original state. To re-select this unit or to select another unit,
follow the same procedure starting with pressing and holding the
ENTER key.
If no remote control activity is sensed for 10 minutes, the HARC will de-
activate security and it will be necessary to re-enter the security code
and reselect this unit following the procedure just described.

AUTOMATIC COLOR BALANCE
Automatic Color Balance is often referred to as Automatic Kinescope
Biasing (AKB). It restores the color balance of the monitor to factory set
values, compensating for aging of components within the monitor,
primarily aging of the phosphors within the cathode ray tube (CRT)
screen.
AKB can be initiated manually by pressing and holding the 1 (one)
key for 6 to 8 seconds. AKB blanks the screen then displays a red
square in the middle of the screen and adjusts the intensity of the
red square until it matches factory set parameters. This process is
repeated for the red square and then repeated twice each for a
green and blue square.
The AKB process can take from one to four minutes.
AKB will change the color drive and background values on the
Color Menu. It will not change the Contrast and Brightness values.
(Note that the color drive and background values can not be
changed manually on the Color Menu when Automatic Color
Balance is enabled. This is indicated by the blue color of the text.)
After completion of the manually initiated AKB process the on screen
display is erased, leaving a blank, black square, until another selection is
made via the remote control or the PREV. CH key is pressed to exit
security.
AKB can be initiated automatically at the same time as Purity Guard.
This will occur if the Automatic Color Balance selection is enabled on the
Selection Menu.
When AKB is initiated automatically, its operation is exactly as
described for the manually initiated function described above,
except that the screen is restored too normal after the completion
of the AKB. It is not necessary to select another menu or to push
the PRE CH key as in the manually initiated case.
** Not available on the 20.

another selection is made via the remote control.
DE-ACTIVATING SECURITY
A jumper selection is provided on the HARC module to activate or de-
activate security. To access this jumper remove the rear of the monitor
and find the HARC module.
Jumper location, labeled J4 is located near the center of the module and
will have jumper installed on one pin of the jumper location in such a way
that there is no connection between the pins of the jumper location.
Moving the jumper from this non-active position to the position where it
covers and connects the two pins de-activates security.

PROGRAMMING PURITY GUARD TIMER
Purity Guard activates the Degauss function and on units with HarcPlus,
the automatic color balance feature of the monitor, once each 24 hour
period. Degauss compensates for the effects of stray magnetic fields
including the earth’s field, from affecting the quality of the picture pre-
sented by the monitor. See Automatic Color Balance for a description.
Degauss is activated at power up which is sufficient for monitors that are
powered down at least once each day. For units that operate continu-
ously, it is recommended that the degauss circuit be operated at a
selected time each day. Purity Guard provides the timer and selection of
time for the degauss function.
As shipped from the factory, Purity Guard is not active. To activate
Purity Guard, select Purity Guard on the selection menu and press the
right arrow key until the word “ENABLED” appears. If Purity Guard is
disabled, the timer can be programmed as described below, but the
degauss action will not occur until Purity Guard is activated.
To set the Purity Guard time, first it is necessary to enter the security
code and unit number, refer to GETTING STARTED earlier in this
manual for the procedures to enter the security code and unit number.
Then press and hold the 9 (nine) key until the following screen
appears (typically 6 – 8 seconds).
