When you solder while repairing, please be sure that there are no cold solder and other debris. Soldering should be finished with the proper quantity. (Refer to the example) 4 Make sure the screws are tightly fastened. Please be sure that all screws are fastened, and that there are no loose screws. 5 Make sure each connectors are correctly inserted. Please be sure that all connectors are inserted, and that there are no imperfect insertion. 6 Make sure the wiring cables are set to their original state. Please replace the wiring and cables to the original state after repairs. In addition, be sure that there are no pinched wires, etc. 7 Make sure screws and soldering scraps do not remain inside the product. Please check that neither solder debris nor screws remain inside the product. 8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord. Damaged power cords may lead to fire accidents, so please be sure that there are no damages. If you find a damaged power cord, please exchange it with a suitable one. 9 There should be no spark traces or similar marks on the power plug. When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary. 0 Safe environment should be secured during servicing. When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely. 2. Adjustments To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification. Adjustments should be performed in accordance with the procedures/instructions described in this manual. 4. Cleaning For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances. 3. Lubricants, Glues, and Replacement parts Use grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied. 5. Shipping mode and Shipping screws To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment.

Amp Unit Heat Sink Heat Sink Amp Unit RCA Holder Move the Amp Unit Fig. 3 Stud Stud 2 2 2 3 3 1 1 1 1 1 2 3 1 A Removing the Amp Unit (Fig. 3) 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 (CN801) Panel for the RCA side A (Since screw threads differ, and screws cannot be used.) 1 2 Screw holes in the PCB are printed with numbers 1 to 8. Remove screws in numerical order. Re-assembly takes the reverse order of disassembly. Remove all of the eight 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. 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 21 5 6 7 8 F E D C B A 5 6 7 8 GM-3100T/XU/EW 7.1.2 CONNECTOR FUNCTION DESCRIPTION (GM-3100T/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 22 1 2 3 4 1 2 3 4 F E D C B A GM-3100T/XU/EW 8. OPERATIONS (GM-3100T/XU/EW) 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. LPF (Low-Pass Filter) Select Switch Set the LPF select switch as follows according to the type of speaker that is connected to the speaker output connector and the car stereo system: LPF Select Audio frequency range Speaker Remarks Switch to be output Type LPF (right) Very Low Frequency range Subwoofer Connect a subwoofer. 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 stan- dard tip screwdriver. 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
