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 270˚C during repairing. • Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). • Be careful not to apply force on the conductor when soldering or unsoldering. 1 Battery-check indicator 2 Power/nR (noise-reduction) switch 3 L-shaped mini plug 4 Microphone 5 Plug holder 6 SENS (microphone sensitivity) selector 7 Spiral groove (for storing the microphone cord) SECTION 1 GENERAL This section is extracted from instruction manual. — 2 — Ver 1.0 2000. 02 w w w . x i a o y u 1 6 3 . c o m Q Q 3 7 6 3 1 5 1 5 0 9 9 2 8 9 4 2 9 8 T E L 1 3 9 4 2 2 9 6 5 1 3 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 2007.04.30 QQ :376315150 手机:13942296513 Note on Schematic Diagram: • All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. • All resistors are in Ω and 1/4 W or less unless otherwise specified. • % : indicates tolerance. • C : panel designation. • Signal path.
