Remove six white screws (M3 x 12). Amp Unit Heat Sink Heat Sink Amp Unit RCA Holder Stud Move the Amp Unit Fig. 3 Stud 2 3 1 A Removing the Amp Unit (Fig. 3) Screw holes in the PCB are printed with numbers 1 to 12. Remove screws in numerical order. Re-assembly takes the reverse order of disassembly. Remove all of the twelve screws. Then, remove the two black screws (M3 x 5). Tighten screws whose length is M3 x 8 or more into the two screw holes so as to raise the Amp Unit above the Heat Sink. Then, remove the Amp Unit. Caution) The Amp Unit is adhered on the Heat Sink with silicon grease. This means forcibly removing the Amp Unit from the Heat Sink may break the PCB. Be aware that the RCA Terminal may break unless the Amp Unit and the Heat Sink are assem-bled following the correct procedures given below. 1) Secure the RCA-side Panel on the Heat Sink with screws. (Fig. 2) 2) Place the Amp Unit on the Heat Sink aligning with two studs. (Fig. 4) 3) Move the Amp Unit until the RCA Holder on the Amp Unit comes in contact with the inside of the Panel. (Fig. 4) Caution in steps 2) and 3) When you place the Amp Unit on the Heat Sink, you will find no positioning marks to determine the direction of two panels. To position them correctly, the Amp Unit needs to be moved to the place where it comes in contact with the RCA-side panel. If you do not position them, an excessive force can be applied to the RCA Terminal. This may result in breakage. 4) Secure the RCA-side Panel and the RCA Holder with screws. (Fig. 2) 5) Secure the Amp Unit on the Heat Sink with screws. (Fig. 3) 6) Secure the Panel for the Power Terminal side in place with screws. (Fig. 2) Fig. 4 RCA Terminal (CN111) Panel for the RCA side (Since screw threads differ, and screws cannot be used.) 1 2 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 28 1 2 3 4 1 2 3 4 F E D C B A GM-5100T/XU/EW 7.1.2 CONNECTOR FUNCTION DESCRIPTION (GM-5100T/XU/EW) 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 29 5 6 7 8 F E D C B A 5 6 7 8 GM-5100T/XU/EW 8.

OFF (left) Full range Full range BFC (Beat Frequency Control) Switch If you hear a beat while listening to an MW/LW broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver. Power Indicator The power indicator lights when the power is switched on. Gain Control If the sound level is too low, even when the volume of the car stereo used along with this power amplifier is turned up, turn gain control on the front of the power amplifier clockwise. If the sound distorts when the volume is turned up, turn the gain control counter-clockwise. • When using with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. When using with an RCA equipped Pioneer car stereo with max. output of 4 V or more, adjust level to match the car stereo output level. • If you hear too much noise when using the speaker input terminals, turn the gain control counter-clockwise. Bass Boost Level Control Switch Bass boost level control can boost the level around the frequency selected by the bass boost frequency control switch from 0, 6, and 12 dB. 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
