Important safety information

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with a dry cloth.

7. Do not block any of the ventilation openings. Install in accordance with the manufacturers instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce

heat.

9. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the

other. A grounding type plug has two blades and third grounding prong. The wide blade or third prong is provided for your safety.

When the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they

exit from the apparatus.

11. Only use attachments/accessories specified by the manufacturer.

12. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used,

use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. The TV should be operated only from the type of power source indicated on the label. If you are not sure of the type of power

supplied to your home, consult your dealer or local power company.

14. Unplug this apparatus during lightning storms or when unused for long periods of time.

15. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such

as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into apparatus, the apparatus has been

exposed to rain or moisture, does not operate normally, or has been dropped.

16. This product may contain lead or mercury. Disposal of these materials may be regulated due to environmental considerations.

For disposal or recycling information, please contact your local authorities or the Electronic Industries Alliance: www.eiae.org

17. Damage Requiring Service – The appliance should be serviced by qualified service personnel when:

ViewSonic Corporation N1750w

3

A. The power supply cord or the plug has been damaged; or

B. Objects have fallen, or liquid has been spilled into the appliance; or

C. The appliance has been exposed to rain; or

D. The appliance does not appear to operate normally or exhibits a marked change in performance; or

E. The appliance has been dropped, or the enclosure damaged.

18. Tilt/Stability – All televisions must comply with recommended international global safety standards for tilt and stability

properties of its cabinets design.

! Do not compromise these design standards by applying excessive pull force to the front,

or top, of the cabinet, which could ultimately overturn the product.

! Also, do not endanger yourself, or children, by placing electronic equipment/toys on the top of the cabinet. Such items could

unsuspectingly fall from the top of the set and cause product damage and/or personal injury.

19. Wall or Ceiling Mounting – The appliance should be mounted to a wall or ceiling only as recommended by the manufacturer.

20. Power Lines – An outdoor antenna should be located away from power lines.

21. Outdoor Antenna Grounding – If an outside antenna is connected to the receiver, 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 Electric Cord,

ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mats and supporting structure grounding

of the lead-in wire to an antenna-discharge unit, size of grounding connectors, location of antenna-discharge unit, connection to

grounding electrodes and requirements for the grounding electrode. See Figure below.

22. Objects and Liquid Entry – Care should be taken so that objects do not fall and liquids are not spilled into the enclosure

through openings.

selected as input source, activation of these keys will cycle through all available TV/CATV channels. While OSD menu is
up, activation of these keys will highlight each available adjustment. The activation time for this switch includes Press and
Hold should be less than half second.

VOL +/-: These two switches shall be visible and accessible on the bottom of front panel control keys. Activation will
increase /decrease loudness of the audio output. In addition, while OSD menu is up, activation of these keys will regulate a
pre-selected adjustment. The activation time for this switch includes Press and Hold should be less than half second.

MENU: This switch shall be visible and accessible on the left side of VOL - switches. Once pressed, this key shall bring
up the corresponding OSD menu(s) based on the selected input source.

SOURCE: This switch shall be visible and accessible on the right side of VOL + switches. Once pressed, this key shall
toggle in a closed loop of the input source selection from TV, AV1, AV2, S-Video, Component, PC

Headphone: This connector is designed purpose to use headphone. Once the headphone connected, then the speakers will
auto mute on audio output.

3.2 How to use the menu

1. Press the MENU button to display each menu

2. Use the cursor up/down to select a menu item.

3. Use the cursor left/right to enter a submenu or enable/disable the function.

7.1.4 IO-Trap

While most configurations of the SPV302A can be programmed by firmware, there are some configurations that must be

determined immediately after the chip is powered-on. The SPV302A adopts an IO-trap mechanism to set these configurations. These

configurations are not changed during the operation of the SPV302A. The SPV302A samples signal states on the video output bus

when the reset signal goes form high to low. These samples values, in turn, set the internal configurations. The following table lists all

the IO-trap values in the SPV302A:

Name Description Note

Trap[0] Extcpu

0: use internal CPU

1: use external CPU (or ICE)

Trap[1] Fastrsten

0: Normal mode (10 ms reset)

1: Fast reset (32 xtal clock)

Trap[2] MPU_I2C

Use external CPU interface

0: use serial I2C interface

1: use parallel MPU interface

Trap[4:3] I2Cslave

Set I2C alave address

00: 68H 01: 6AH

10: 6CH 11: 6EH

Trap[5] Extusb 1’b1

Trap[6] Extflash

0: executes internal ROM code

1: executes external ROM code

Trap[7] Lvrsten

0: disables low voltage reset

1: enable low voltage reset

Trap[9:8] Lvdelay

Configures low voltage detector response time

00: delay 64 xtal clocks

01: delay 128 xtal clocks

10: delay 256 xtal clocks

11: delay 512 xtal clocks

Trap[10]

0: set video output interface to VOUT port

1: set parallel MPU interface to VOUT port
