On illumination

In order to obtain the best quality for the projected image, it is essential
that the ambient light which is allowed to fall on the screen be kept to an
absolute minimum.

When installing the projector and screen, care must be taken to avoid
exposure to ambient light directly on the screen. Avoid adverse illumina­tion on the screen from direct sunlight or fluorescent lighting fixtures.

The use of controlled ambient lighting, such as incandescent spotlight or
a dimmer, is recommended for proper room illumination. Where possible,
care should also be taken to ensure that the floors and walls of the room
in which the projector is to be installed are non-reflecting, dark surfaces.
Brighter surfaces will tend to reflect and diffuse the ambient light and
hence reduce the contrast of the projected image on the screen.

CONTROLLING

Battery installation in the RCU.

A new battery (not yet installed to save the battery life) is delivered inside the plastic bag with the
power cord. Install the battery as follows :

Remove the battery cover on the backside of the RCU by pushing the indicated handle a little to the
bottom of the RCU. Lift up the top side of the cover at the same time (fig. 1).

Insert the new 9 V battery (type 6F22S or equivalent) in the lower compartment and connect the
battery to the contact plate.

Insert the battery into the lower compartment and put the cover back.

4-1

The DTV-943 can be controlled with
a. The RCU
b. The hardwired RCU (cable not included)
c. The local keyboard

The procedure and results of controlling the projector with either of these
RCU options is essentially the same.

How to use your RCU

a) Point the front of the RCU towards the projector

b) RCU used in a hardwired configuration.

c. Using your RCU.

Before using your RCU, it is necessary to enter the projector address into
the RCU (only when that address is between 1 and 9). The projector with
the corresponding address will listen to that specific RCU.
When address 0, ‘zero address’is programmed into the RCU, every pro­jector, without exception will listen to the commands given by this RCU.

How to display a projector address?

Press the ADDRESS key (recessed key on the RCU) with a pencil. The
projector’s address will be displayed in a ‘Text box’. This text box dis­appears after a few seconds.

To continue using your RCU, it is necessary to enter the same address
with the digit buttons (address between 0 and 9). For example, if the
Address Key displays projector address 003, then press the “3” digit but­ton on the RCU to set the RCU’s address to match the projector’s address.
Do not press digit 003. This will address the remote to ‘0’and control all
projectors in the room.

How to program an address into the RCU?

Press the ADDRESS key (recessed key on the RCU) with a pencil and
enter the address with the digit buttons. That address can be any digit
between 0 and 9.

When programming ‘0’, zero address, the RCU will control a projector
regardless of the projector’s address. This feature allows multiple projec­tors with different addresses to be controlled by a single RCU.

Plug one end of the remote cable in the connector on the bottom of the
RCU and the second side in the connector in the rear panel of the DTV­943 labeled ‘REMOTE’.

ProjectorAddress

a. Hardware set up of the projector address.

Every projector requires an individual address between 0 and 255 which
is set with hardware DIP switches inside the projector. To change that
address, contact a RUNCO authorized technician.

b. How to control the projector.

The projector’s address may be set to any value between 0 and 255.
When the address is set, the projector can be controlled now with :

-the RCU for addresses between 1 and 9.

-computer, e.g. IBM PC (or compatible), Apple MAC, etc. for
addresses between 0 and 255.

Note : A projector will respond to a RCU set to an address of ‘0’regard­less of what address is set in the projector itself. Address “0” is therefore
a universal address.

4-2

Input selection.

Two possible ways of selecting an input :
a) Display General access menu with RCU by pressing ADJ button.

This brings up a secondary general access menu. Choose source selec­tion and highlight desired source.

b) With the local keypad :
Press first the ADJUST key to display the General access menu. Use
the control disk to highlight the desired source number. Choose from
table above. Push the control disk up or down to move the cursor up and

down, push the control disk to the left or to the right to move the cursor
to the left and to the right.
Press ENTER to confirm your selection.

When a valid and available source is selected, there will be information
displayed on the screen about that source. This information includes :

- Source number

- Horizontal frequency

- Vertical frequency

When the entry is a non valid source number, a warning appears on the
screen : ‘input not available’.

When a valid source number is selected, the projector will display this
source or it will wait on the selected source number until the source
becomes available. A message ‘source not available’will be displayed
for a short time.

4-3

Analog Picture Controls

The analog picture controls can be adjusted with the RCU. The control
keys are located on the lower right side of the key panel of the RCU and
indicated with the name of the control and an icon.
When an analog picture control is pressed, a text box with bar scale and
