Standard Satellite Array Procedures

Notes:

• The standard satellite arrays are non repairable. These arrays have cloth grilles, and are larger than the Gemstone^TM arrays.
• The only parts that can be replaced on the standard arrays are the grille and the nameplate.

1. Grille Removal
   1. Place the satellite array on its back on a bench. Use your thumb to press down on the array grille at the center of the curve near the side. Use a flat tip screwdriver to pry the end of the grille off of the array enclosure. Repeat this at the other end of the grille.
      
      Re-Assembly Note: Align the grille so that the Bose^® logo is facing the same direction as the arrows on the front of the array enclosure. Press the grille in place. It should latch to the enclosure at each end.

Gemstone Satellite Array Procedures

1. Grille Removal
   1. Using a scribe or small flat-tip screw-driver, grasp the edge of the grille. Gently pull the grille away from the enclosure.
      
2. Driver Removal
   1. Perform procedure 1.
   2. Remove the four screws that secure the driver to the enclosure. Lift the driver out of the enclosure and cut the wires as close to the driver as possible.

TEST PROCEDURES

Satellite Array Procedures

Notes:

• The satellite arrays are non-repairable.
• The grills can be replaced using the disassembly/assembly procedures.
• Each satellite array contains two identical drivers that are wired independently.
• You must test each of them separately

1. DC Resistance Test
   1. Using a DMM, measure the DC resistance of each of the array drivers. Each should measure 3.2 Ohms + 10%.
2. Phase Test
   1. Remove the array grille using array disassembly procedure 1.
   2. Observing polarity, apply a +6 Vdc level to one driver on the array input connector.
   3. Observe the driver under test. When the DC level is applied, the driver should move outward. If it does, the driver is wired correctly. If not, it is wired incorrectly. Repeat steps 2.2 and 2.3 for the other driver in the array.
3. Air Leak Test
   1. Apply a 180 Hz, 3 V rms signal to one of the Twiddler drivers in the satellite array for 5 seconds minimum.
   2. Listen for air leaks around all enclosure seams, joints and the input connector. Air leaks will be heard as a hissing or sputtering noise. Repair any air leaks. All repairs must be hidden.
   3. Listen for air leaks around all enclosure seams, joints and the input connector. Air leaks will be heard as a hissing or sputtering noise. Repair any air leaks. All repairs must be hidden.
   4. Listen for any rubbing or ticking noise from the Twiddler. Replace any driver that is defective.
      Note: There is a normal suspension noise. To distinguish between a rub or tick and suspension noise, displace the cone slightly with your finger. If the rubbing can be made to go away or get worse, then it is a rub or tick. If the noise stays the same, it is suspension noise.
   5. Repeat steps 3.1 to 3.3 for the other driver in the array.
4. Frequency Sweep Test
   1. Jumper both of the drivers in a single array together. Both center pins of the array connector are negative (-). The two outer pins are the positive (+) pins.
   2. Apply a 100 Hz, 3.0 V rms signal to both of the array drivers.
   3. Slowly sweep the signal generator from100 Hz to 2.0 kHz. Listen for any extraneous noises such as buzzes, rattles, ticks, port noise or distortion. Replace any array with an extraneous noise that can be heard at a distance greater than 1 foot (0.3m).

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:
   1. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL) 60065 / IEC 60056 paragraph 9.1.1. With the unit AC switch first in the ON position and then in 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, screw heads, 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. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.
   2. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic cabinet part on the unit. When testing 3 wire products, the resistance measured to the product enclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposed input/output connectors should be between 4 and infinite MOhms. When testing 2 wire products, the resistance measured to exposed input/output connectors should be between 4 and infinite MOhms. 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.

The CineMate^® Series II contains no user-serviceable parts. To prevent warranty infractions, refer servicing to warranty service stations or factory service.

Danger of explosion if remote battery is incorrectly replaced. Replace with only Duracell, Eveready, Energizer, Maxell or Toshiba CR2032 or DL2032 3-volt lithium battery.
