PRODUCT OVERVIEW

The PRO895X HD Projection Display system is a high reso- lution multiple signal format display monitor. It uses 7” high performance liquid cooled CRTs. Each CRT has a 5” active phosphor area and a 90 degree deflection angle. The CRTs use high-resolution color corrected multi-layered hybrid lens assemblies.

Horizontal scan frequency is from 15 to 40 KHz. Vertical scan frequency is from 40 to 100 Hz. Video system signal bandwidth is 35 MHz. The projected display diagonal size (4:3 aspect ratio) is adjustable from 60” to 240”. Supported signal formats include NTSC (3.58 and 4.43), PAL (M,N,B, and G), VGA, Mac II, and Grand Alliance HDTV. Signal input options include 5 BNC connectors (R,G,B,V,H), composite video, S-Video (Y-C), and an RS232 serial data port. The IR control format is addressable (0 - 99) for use with multiple unit installations. Each PRO895X comes with a Universal customer remote control and a service/align- ment 5-function MBR3470 remote control.

From the factory, the PRO895X comes aligned for a 80” wide display. The preset projection distance is 96 3/8” and configured for a ceiling mount. You may customize the setup to be floor or ceiling mounted and rear or front pro- jected. Refer to the setup section before attempting an installation.

The convergence system is a digital controlled analog sys- tem with 10 signal format preset and 5 customer option memory locations. The preset format memory locations

cannot be altered in the field. Each preset format has a custom memory location to store customized setup data. Each customized setup has a separated memory location for each aspect ratio (4 X 3, letter box, compressed, and

16 X 9). You must set up and converge the system for each aspect ratio that will be used. The five customer memory locations are for signal formats that do not match the ten factory preset signal formats. There is also the option to copy the stored format data from one memory location to another. This allows faster setup when several similar for- mats are used. Internally generated signal patterns also aid with setup of convergence. The internal pattern gener- ator may sync from the internally preset signal formats or it will sync from an external signal source. This is helpful for on-site full convergence or just a touch up. You must use the customer’s signal source to perform blanking and phase adjustments.

The PRO895X cabinet is comprised of three pieces. Removal of the case allows full maintenance access to the systems electronic and mechanical assemblies. Front and rear mounted IR detector assemblies allow almost no inter- ference to IR control. There are adjustable (and removable) feet on the bottom of the case.

CABINET REMOVAL

Note the location of the screws which need to be removed to allow access to the components.

Caution:

Disconnect the PRO895X from power before attempting to remove the cabinet.
