Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with a dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. 8. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. 9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 10. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles and the point where they exit from the apparatus. 11. Only use attachments/accessories specified by the manufacturer. 12. Use only with the cart, stand, tripod, bracket or table specified by the manufacturer or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. 13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. 15. Do not expose this apparatus to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the apparatus. 16. To completely disconnect this apparatus from the AC Mains, disconnect the power supply cord plug from the AC receptacle. 17. The mains plug of the power supply cord shall remain readily operable. 18. Do not expose batteries to excessive heat such as sunshine, fire or the like. Warnings and Precautions • WARNING: To prevent fire or shock hazards, do not expose this unit to rain or moisture. • WARNING: Do not place the unit on top of any soft, porous, or sensitive surfaces to avoid damaging the surface. Use a protective barrier between the unit and surface to protect the surface. • WARNING : Where the mains plug or appliance coupler is used as the disconnect device, such disconnect device shall remain readily operable. • Note : This device uses an internal rechargeable lithium-ion battery that should last the lifetime of the device. If you suspect your battery may be dead after several attempts to charge, please contact COBY for support. • Never disassemble the unit or attempt to remove the battery as that could cause leakage of an electrolytic substance.  FCC Warnings WARNING: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and recei…

Main parameters: Power adaptor: 3.7V 900mAh built-in lithium battery Charching voltage: DC 5V Speaker resistor: 4Ohm Power consumption output: 1.5W*2 Circuit Description 1.DS-1073 is a 2.0(stereo) portable Bluetooth speaker 2. DS-1073 can support AUX and Bluetooth speaker. 2.1 When play AUX music, sound frequency L&R signal enter into 3(R IN)&18(L IN) of IC HT6808(U2) through JK1(earphone dock), after amplifying, transferring into L&R speaker from amplifier IC 5(RP+), 8(RO-) and 13(L-) 16(L+). 2.2 The shift between AUX and Bluetooth can be controlled by JK1(earphone dock). When AUX signal is input, JK1(earphone dock) switch outputs L electrical level, counter wisely, JK1(earphone dock) switch outputs H level. 2.3 While playing AUX music, the Bluetooth module power will be cut off to stop working through JK1(earphone dock) switch to control triode Q1(3904) and Q2(3906). 2.4 Under Bluetooth working status, due to no AUX signal input, it can use JK1(earphone dock) switch to control triode Q1(3904) and Q2(3906) to make it pass, then the Bluetooth can be charged by power adaptor which will help Bluetooth work.. Bluetooth signal L&R inputs into bi-mold noisse interruption circuit U3 (LM358) , the new signal will be output from 1&7 of U3.Sound frequency L&R signal enter into 3(R IN)&18(L IN) of IC HT6808(U2) through JK1(earphone dock), after amplifying, transferring into L&R speaker from amplifier IC 5(RP+), 8(RO-) and 13(L-) 16(L+). 2.5 The Bluetooth Module F-3089 utlizes 12MHz OSC. Power charging: Electricity of DS-1073 is supplied by 3.7V 900mAh built-in lithium battery. When the power is limited, it can be charged by outer DC 5V adaptor, which connected with mini USB cable, using charging management IC EUP8054(U3) to transfer the power to device.
