Then remove (glue will be melted). (Fig. S-1-6) 4.Release the flat pack-IC from the CBA using tweez

3、ers. (Fig. S-1-6) CAUTION: 1.The Flat Pack-IC shape may differ by models. Use an appropriate hot-air flat pack-IC desoldering machine, whose shape matches that of the Flat Pack-IC. 2.Do not supply hot air to the chip parts around the flat pack-IC for over 6 seconds because damage to the chip parts m

Installation 1.Using desoldering braid, remove the

12、 solder from the foil of each pin of the flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily. 2.The “” mark on the flat pack-IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark matches the 1 on the PCB when positioning for installation. Then presolder the four corne

13、rs of the flat pack-IC. (See Fig. S-1-8.) 3.Solder all pins of the flat pack-IC. Be sure that none of the pins have solder bridges. Instructions for Handling Semi- conductors Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electrostatic charge during

14、unpacking or repair work. 1. Ground for Human Body Be sure to wear a grounding band (1 M) that is properly grounded to remove any static electricity that may be charged on the body. 2. Ground for Workbench Be sure to place a conductive sheet or copper plate with proper grounding (1 M) on the workben

15、ch or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing. Example : Pin 1 of the Flat Pack-IC is indicated by a mark. Fig. S-1-

35、FOR SERVICING How to Enter the Service Mode About Optical Sensors Caution: An optical sensor system is used for the Tape Start and End Sensors on this equipment. Carefully read and follow the instructions below. Otherwise the unit may operate erratically. What to do for preparation Insert a tape int

36、o the Deck Mechanism Assembly and press the PLAY button. The tape will be loaded into the Deck Mechanism Assembly. Make sure the power is on, connect TP502 (S-INH) to GND. This will stop the function of Tape Start Sensor, Tape End Sensor and Reel Sensors. (If these TPs are connected before plugging

37、in the unit, the function of the sensors will stay valid.) See Fig. 1. Note: Because the Tape End Sensors are inactive, do not run a tape all the way to the start or the end of the tape to avoid tape damage.
