IMPORTANT SAFEGUARDS

1. Read and understand all instructions before using. Pay particular attention to areas where this

WARNING - Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

Caution - Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It may also be used to alert against unsafe practices.

2. Close supervision is necessary when any appliance is used by or near children. Do not leave

appliance unattended while in use.

3. Never look directly into the projector lens when the lamp is on. The metal halide lamp produces

a strong light which could damage your eyesight.

4. Care must be taken as burns can occur from touching hot parts.

5. Do not operate appliance with a damaged cord or if the appliance has been dropped or

damaged – until it has been examined by a qualified service technician.

symbol is shown.

ENGLISH

6. Position the cord so that it will not be tripped over, pulled, or contact hot surfaces.

7. If any extension cord is necessary, a cord with a current rating at least equal to that of the

appliance should be used. Cords rated for less amperage than the appliance may overheat.

8. Always unplug appliance from electrical outlet before cleaning and servicing and when not in

use. Grasp plug and pull to disconnect.

9. To reduce the risk of electric shock, do not immerse this appliance in water or other liquids.

10. To reduce the risk of electric shock, do not disassemble this appliance, but take it to a qualified

technician when service or repair work is required. Incorrect assembly can cause electric shock when the appliance is subsequently used.

11. Connect this appliance to a grounded outlet.

12. Do not expose this projector to direct sunlight, or use it outside.

13. Keep all ventilation openings free of any obstructions.

14. Always open the lens shutter when the projection lamp is on.

15. Do not look directly into light beam of laser pointer. The pointer produces a strong light which

could damage your eyesight.

16. The projection lamp contains mercury. Always dispose of it in a proper manner according to local

regulations.

Note 1: MAC adapter is necessary to set the resolution mode.

Projector is compatible with 13 inch mode and 16 inch mode.

Set all dip switches OFF except those indicated in the chart. For example:

MAC 13" mode = switch 1, 5 and 6 are ON MAC 16" mode = switch 2, 5 and 6 are ON

(Example of 16 inch mode)

Note 2: Some input sources may not be displayed properly because they are not compatible with the projector.

A.7 Connection to the Control Signal Terminal

a) Mouse emulation

(1) While the projector and computer are turned OFF, connect the projector and the mouse terminal of

computer using an appropriate cable. (PS/2, Serial or ADB) (2) Turn ON the projector. (3) Turn ON the computer. (4) Select the correct mouse driver for the application. See computer's User Manual for this procedure.

✔ Note

In some Notebook computers which have internal pointing device, mouse emulation will not work unless the internal pointing device is disabled. In this case, disable the internal pointing device in BIOS setting. Check the computer's manual for procedure to follow to disable internal pointing device in BIOS setting.

Caution

Turn off the power to both the projector and computer before connecting. Connect the computer to the control terminal of the projector using the appropriate cable.

Serial Command Codes

All numbers in this document are in Hexadecimal. You must send at the same communication setting as the projector and use a null modem serial cable to connect to the projector.

There are four types of messages for the MP8740, 1) ASK, 2) REPLY, 3) SET and 4) DEFAULT. Ask Code: User:

20 XX

XX is the attribute you are checking. Projector:

1Y XX Y bytes of data

This is a reply code. The Y is the number of extra bytes that come after the command. The XX is the same as in the Ask code. Set Code: User:

3Y XX Y bytes of data

XX is the attribute you are checking. The Y is the number of bytes for the data. Projector:

1Y XX Y bytes of data

This is a reply code. The Y is the number of extra bytes that come after the command. The XX is the same as in the Set code.

Default Code:

User:

40 XX

XX is the attribute you are checking. Projector:

1Y XX Y bytes of data

This is a reply code. The Y is the number of extra bytes that come after the command. The XX is the same as in the Ask code.

Errors: For an error, the projector will reply with the same code that was sent but with a 0 in the first nibble.
