5、ENTS Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing Keep the temperature of soldering iron around 270C during repairing. Do not touch the soldering iron on the

6、same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. 1. SERVICE NOTE3 2. GENERAL 4 3. DISASSEMBLY 3-1.

Because the PH701 is mounted on the Main board, auto stop is activated and reel rotation cannot be detected when the Main board is removed. To check the operation of mechanism deck and voltage without the Main board, follow the proced

10、ure as described below. How to remove the Main board (opening the Main board) 1) Refer to page 5 “3. Disassembly”. How to enter the fast forward/rewind modes 1) Input the square wave to the TP41. (Refer to the illustration below.) 2) Press the fast forward/rewind keys. 3) Turn on the S301. How to en
