(Less than 0.3W at the normal temperature). If an abnormal current flows to P.SW due to an excessive input or unusual signal, P.SW heats up and the resistance rapidly increases. With this function, the speakers are protected from excessive input or unusual signal. The resistance value increases even when using a soldering iron for repairing, so allow it to cool before using. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 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 3 1 2 3 4 1 2 3 4 C D F A B E S-HF31-LR 1 1 1 Input Terminal 1 1 1 12 13 1 Screw 11 3 4 1 10 1 1 4 Part Name No. Num. 9 8 7 6 5 4 3 2 1 Catch Screw Grille Cabinet Model Label Duct Network Assy Acoustic Absorbent Tweeter Woofer Gasket 13 PRODUCT APPEARANCE www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 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
