WALL MOUNT BRACKET

Installation Manual

Thank you very much for purchasing the Wall Mount Bracket SPM-K30. Be sure to read this manual thoroughly before using this bracket. After you have read this manual, retain it for future reference.

When installing the Digital Sound Projector using this bracket, all installation work must be performed by a qualified contractor or dealer personnel. The customer must never attempt to perform this installation work. Improper or inadequate installation could cause the Digital Sound Projector to fall, resulting in personal injury.

SAFETY INSTRUCTIONS

Always follow the instructions set forth in this manual when installing the Digital Sound Projector using this bracket. Improper or inadequate installation could cause the Digital Sound Projector to fall, resulting in personal injury. The installation must be secure enough to bear the weight of the Digital Sound Projector, the wall bracket and other hardware indefinitely, and must also be secure enough to withstand vibrations. Improper or inadequate installation could cause the Digital Sound Projector to fall, resulting in personal injury. To ensure safety, all screws must be tightened securely. Loose screws could cause the Digital Sound Projector to fall, resulting in personal injury. Make sure to leave adequate ventilation space around the unit to allow heat generated by the Digital Sound Projector to dissipate. Failure to provide adequate space around the unit could cause the Digital Sound Projector to overheat internally, resulting in a fire. Never hang from the Digital Sound Projector or the wall bracket. Hanging from the Digital Sound Projector or the wall bracket could cause the Digital Sound Projector or the wall bracket to fall, resulting in personal injury. Once the Digital Sound Projector is installed, safety checks should be conducted on a regular basis. If the Digital Sound Projector is used over an extended period of time, screws can become loose and the installation can become weaker due to the passage of time, vibrations, etc.

INSTALLATION PROCEDURE

Make sure to leave adequate ventilation space around the unit and follow the instructions below. The illustrations used in each step are the examples of YSP-800 and YSP-900.
1 Attach the large wall mount bracket to the wall.
In order to secure the unit to the wall, you will need to attach the bracket to the wall first in a manner befitting the structure and quality of the wall. Choose a location where the wall can bear the weight of the whole unit. Before installing the bracket, make sure of the size (see DIMENSIONS on the first page of this manual). 4 mm Tapping Screw (commercially available) Installation example In order to secure the unit to the wall, drive six (or more) tapping screws from the outside through the holes in the wall mount bracket.
Washer (commercially available) Installing into a dry wall 25 mm or more Installing directly into a wall, etc. 25 mm or more
Beam, etc. Dry wall Note Choose a secure wall or beam to fasten the screws. Do not install them into walls made of weak material that can easily come off, such as mortar or plywood wall panels. Loose screws could cause the projector to fall, resulting in personal injury.
2 Detach the metal apparatuses from the Digital Sound Projector. (Some models of YSP-800 only)

If the metal apparatuses are attached to the rear panel of your Digital Sound Projector, detach them from the rear left and right sides. If the metal apparatuses are not attached to the rear panel of your Digital Sound Projector, proceed to step 3.

Metal apparatus

01_EN_SPM-K30.fm Page 6 Monday, June 18, 2007 5:59 PM
3 Attach the small wall mount brackets to the Digital Sound Projector.
The small wall mount brackets vary depending on the type of the Digital Sound Projector. Refer to the following table for details on the type of the Digital Sound Projector and the compatible small wall mound brackets (Type A or B). Use supplied projector mounting screws (M6 x 4 for YSP-4000, YSP-40D or HTY-7040 and M4 x 8 for other models) to securely attach the two small wall mount brackets to the rear left and right sides of the Digital Sound Projector.

I SERVICE PRECAUTIONS /

Safety measures
Some internal parts in this product contain high voltages and are dangerous. Be sure to take safety measures during servicing, such as wearing insulating gloves. Note that positions indicated below are dangerous even after the power is turned off because an electric charge remains and a high voltage continues to exist there. Before starting any repair work, perform discharge by connecting a discharge resistor (5k-ohms/10W) between terminals at following positions. The time required for discharging is about 30 seconds. 1. C502 on INPUT (1) P.C.B. 2. C523 on INPUT (1) P.C.B. Refer to PRINTED CIRCUIT BOARDS: INPUT (1) P.C.B.

Caution for P.C.B. replacement
When replacing INPUT (1) and INPUT (2) P.C.B.s, be sure to replace them at the same time. Installing either P.C.B. of different version from the other may cause failure of operation.

7. RS-232C

This menu is used to check transmission of the data and the flow port of the hardware. With the power turned off, short between pins No. 2 (RxD) and No. 3 (TxD), and between pins No. 7 (RTS) and No. 8 (CTS) of the RS232C terminal. (Be sure to turn off the power when shorting the pins.) Start self-diagnostic function and select the menu. There are two sub-menu items.

RxD TxD

RTS CTS
TxD/RxD DATA The sub-menu is used to check transmission of the test data. OK appears when the data is transmitted properly and NG when it is not. In this mode, NULL command transmission is continued after the test command is transmitted.

8. FACTORY PRESET
This menu is used to reserve and inhibit initialization of the back-up RAM.
PRESET INHIBIT (Initialization inhibited) / RAM initialization is not executed. Select this sub-menu to protect the values set by the user.
PRESET RESERVED (Initialization reserved) / Initialization of the back-up RAM is reserved. (Actually, initialization is executed the next time that the power is turned on.) Select this sub-menu to reset to the original factory settings or to reset the RAM. Any protection history will be cleared.

9. AD DATA CHECK

This menu is used to display the A/D conversion value of the main microprocessor which detects panel keys of the main unit and protection functions in % using the sub-menu. During signal processing, the condition before execution is maintained. PS (Power supply voltage protection detection) * When the value of PS, P2 and P3 is not at the normal value level, the protection function works and the power is turned off. (Reference voltage: 3.3V=100%) PS (PS1) Voltage detects: Normal value: P2 (PS2) Voltage detects: Normal value: P3 (PS3) Voltage detects: Normal value: -24 V, +5.3X (B model), +5 V, +5I (A, B models) 48.7 to 91.3 % (1.6 to 3.0 V) +12 V, T+10 (K, A, G, E, L, V models), D+12 63.9 to 88.2 % (2.1 to 2.9 V) +3.3 V 66.9 to 85.2 % (2.2 to 2.8 V)
* The normal value has been revised from 2.5V (measured value) to 3.3V (indicated value) by the voltage dividing resistor.

10.IF STATUS (Input function status)
Using the sub-menu, the status data is displayed one after another in the hexadecimal notation. During signal processing, the status before execution of this menu is maintained. * The details of the following status information can not be disclosed because of the development purpose. * The figures in the diagram are given as reference only. IS1-3 (Internal status): Indicates the status information of the microprocessor.
