Page 3 SAFETY INFORMATION 1. Parts that have special safety characteristics are identified by the symbol on schematics or by special notes on the parts list. Use only replacement parts that have critical characteristics recommended by the manufacturer. 2. Make leakage current or resistance measurements to determine that exposed parts are acceptably insulated from the supply circuit before returning the unit to the customer. Use the following checks to perform these measurements: A. Page 4 ELECTROSTATIC DISCHARGE SENSITIVE (ESDS) DEVICE HANDLING This unit contains ESDS devices. Handle boards by the edges only. Unbalanced input, 42k. The 802C system controller automatically selects the proper crossover function and equalization curve for a given system application through use of a switching network operating in conjunction with the unit's output jacks. You must test all modes of the 802C to assure proper operation. Frequency 55Hz 750Hz 15kHz 1.http://www.amedar.com/images/bose-802-series-2-service-manual.pdf2 Perform the test below to verify that the mode select operation is working properly. Approval from the Field Service Manager is required before ordering. 2. The individual parts located on the PCB are listed in the Electrical Part List. 3. This part is critical for safety purposes. Failure to use a substitute replacement with the same safety characteristics as the recommended replacement part might create shock, fire and or other hazards. 4. RC-4156 is to be used ONLY as a replacement for U5 and U6.

Refer to Figure 3 below for the following procedures. Please check your inbox, and if you can’t find it, check your spam folder to make sure it didn't end up there. Please also check your spam folder. Use only replacement parts that have critical characteristics recommended by the manufacturer. Use the following checks to perform these measurements: With the unit AC switch first in the ON position, then in the OFF position, measure from a known earth ground (metal water pipe, conduit, etc.) to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the unit power cord plug in the outlet and repeat test.When the exposed metallic part has a return path to the chassis, the reading should be between 1 and 5.2 Megohms. When there is no return path to the chassis, the reading must be “infinite”. If it is not within the limits specified, there is the possibility of a shock hazard, and the unit must be repaired and rechecked before it is returned to the customer.www.holderit.com/wp-content/plugins/formcraft/file-upload/server/content/files/1626bcaa44ef57---case-580-super-le-manual.pdf We recommend the following precautions when repairing, replacing or transporting ESDS devices. Handle boards by the edges only. Do not insert unprotected devices into materials such as plastic, polystyrene foam, clear plastic bags, bubble wrap or plastic trays. In addition to signal routing based on equalization requirements, the switching network indicates mode of operation on its front panel. The front panel also includes high-cut and low-cut switches which decrease line output by 4dB at 55Hz and by 10dB at 16kHz. Sharp subsonic and ultrasonic band-limiting filters reduce power waste, stage noise, high-frequency instability, and interference.This manual will identify the different procedures, PCB layouts, and components where necessary.

By many reports, it has been a hobby for many years. Using pictures as the basis for the diagrams is just a recent fad. Creating diagrams of virtually anything is possible with the use of all Google Docs. The easiest way to create a diagram in Google Docs would be to insert the images which you have in your own document. This makes them real, even if they are on paper. You can then drag and drop them on the canvas area in your diagram. Obviously, it requires a bit more work than that in case you have a great deal of pictures. To do so you want to have the ability to copy a picture and use it as your own diagram. When you know a particular way to eliminate the white space, you will have the ability to insert a couple of items with no looking awkward. You might try using some colors that fit the background to assist. In case you have a fantastic eye, you might even be able to find a diagram in a picture. If you can, you should try to find out whether there's a color or background that doesn't clash with the image. The perfect way to compose a diagram in Google Docs would be to use pictures. The bigger the images you opt for the better. But if you are writing a diagram about your pet lizard, you can use a picture of a pet lizard instead of a photo of your pet lizard. You might even add a second dimension to the way to make a Venn diagram from Google Docs by adding text to the image. Since the images are generally simple, they will have no text. Whenever you're using images to make a diagram, it is best to use simple graphics. As far as what to place on each side of your diagram goes, it's excellent to use two identical images. Many people decide to use more than two identical pictures. It is dependent upon the number of different elements you are including. Two is probably sufficient for many diagrams. But whenever you do decide to use more than two pictures, you need to include a couple of variation images so you can keep things fresh.So, no text on the other hand, no text on the ideal side. To bring the text, then you will need to insert the text into your diagram, then copy it, use it as your text, and paste it back into your diagram. You may repeat this process as far as you need, and it will not take long. Though it's a fun way to understand how to make a Venn diagram, it is vital to be sure that you have all the images which you need to utilize your diagram properly. Remember, if your diagram appears the same, it will look very strange when you are trying to publish it. You can always go back and add more components, but if you are still having difficulty, it is excellent to practice before attempting to publish it. We will get back to you in 24 hours. Thank you.

Refer to the figure below. 3.1 Apply a 10 Vrms, 10 Hz signal to the speaker input connector. 1.2 All driver cones should move outward. Referring to figure 1, rewire any driver that moves inward. 3.2 No extraneous noises such as rubbing, scraping or ticking should be heard. Note: To distinguish between normal suspension noise and rubs or ticks, slightly displace the cone of the driver with your fingers. If the noise can be made to go away or get worse, it is a rub or tick and the driver should be replaced. If the noise stays the same, it is normal suspension noise and the driver is fine. Amplifier 4.1 Apply a 15 Vrms, 65 Hz signal to the speaker input connector. 4.2 Listen for air leaks around the drivers and cabinet seam. Reposition or replace any gasket found to leak. Repairs made to the cabinet seam should not be visible from the exterior of the speaker. If the voltage is out of range, check the crossover components and wiring.
