Wireless Speaker System Model NO: DS-955B, ISP822B Instruction Manual User Guide Congratulations on the purchase of your new wireless speaker system. To get the most from your speaker system, please take a few minutes to read the following instructions and familiarize yourself with the operation of the unit. Before setting up the unit, check that the following items are included with the box: 1. Wireless Speaker System 2. AC Power Adaptor 3. 3.5mm Audio Cable for Aux Input 4. Remote control Unpacking and Installation Unpack your unit carefully. We recommend that you save the box and packing materials, in case you wish to store the unit, or if you ever need to return it for service. To avoid damage to the unit, never place it near heat sources such as radiators, in front of heating vents or in direct sunlight. Keep it away from water. For Your Safety When disconnecting the DC power cord from a socket, pull the plug out. Never try to remove the plug from the socket by pulling the cord. Never handle the DC power plug with wet hands-this can cause electric shock. Care and Maintenance for the Unit When cleaning the unit, you should first unplug it from the power supply. Use only a dry lint free cloth to wipe the unit. Never allow water or any other liquids to get inside the unit while cleaning. Unplug the unit if you are not using it for an extended period of time. Note: We suggest you wipe the Charging Base and speakers periodically to ensure good contact between the Charging Base and speaker contacts. WA R N I N G : Servicing should be carried out by qualified personnel only. To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. Dangerous high voltages are present inside the unit; do not try to open it. To prevent risk of fire or electric shock, do not leave any objects filled with liquids, near the product, such as vases. Never put lighted candles near the unit. The batteries are not user replaceable. If the batteries become weak , take the unit to a service center to have a qualified technician replace them. CAUTION: If the plug or the power supply cord needs to be replaced, ensure that the replacement complies with manufacturer’s recommendations and specifications. If the Unit Requires Servicing Do not attempt to repair the unit yourself. All repairs should be done by a qualified service technician. To avoid risk of electric shock, ensure that the plug is fully inserted into the wall socket. Power supply source: AC 100~240V/50Hz~60Hz. A. Speaker Base (Top view) A1. POWER A2. MODE A3. REV A4.

Standby button Ready for use: The sound comes from two speakers which have a rechargeable lithium battery built-in with an individual amplifier. The wireless function will automatically be activated as soon as the speakers are removed from the base station. You can then enjoy the music from every room in your home. TO PLAY IPOD/IPHONE 1. Plug the AC adaptor into the DC in port at the rear of the speaker base, then into a power supply. (100-240V/50Hz-60Hz AC electrical outlet). Note: The rechargeable lithium battery is built in. Before use we recommend charging the unit for 3 hours. Once the Speaker Base is plugged in, it will automatically charge the speakers when they are placed on the Base. While charging the LED indicator is red and will turn green when fully charged. Once the speakers are fully charged it is safe to remove them from the Speaker Base. TO PLAY IPOD/IPHONE Press the power button on the speaker base to turn the unit on. Switch on the speakers to play your iPod. Note: Speaker is paired well in factory, end user no need to pair by themselves, in case speaker lost the connection, please follow up below procedure: Press pair button on speaker unit and speaker base, the blue Led on speaker unit and red LED on Speaker base will be flashing, once paired, both Led will stop flashing and a paired pop sound come out showing speaker has been paired well. Note : Sometimes the speaker will give off noise after the power is turned on. This is normal as the unit is searching for the wireless connection . The noise should stop after the connection is paired. In order to avoid interference, do not turn on other wireless devices simultaneously. TO PLAY IPOD/IPHONE 3.Use “” or “” to adjust to a proper volume level. You should now be able to freely move the speakers from room to room.(Subject to surroundings this speaker covers an area up to 30m in an open area) To Play Auxiliary Audio Sources Press Mode button to switch to AUX mode, connect one end of the 3.5mm audio cable to the audio output port of an auxiliary audio device (MP3, MPEG4, PC, CD player, etc ) and connect the other end of cable to the Aux input port at rear of the base station . Product Specifications： Each speaker has its own separate amplifier and receiving system Compatible with iPod/iPhone AC adapter and 3.5mm audio cable included Charge Time: 3 hours for first use Power Supply Source: AC 100~240V/50Hz-60Hz 2pcs of Full Range Speaker: 2.75inch Wireless Working Distance: up to 30m in an open area without interference Output Power: 2.5W×2 Frequency Response: 200Hz-20KHz Mobile Phone: 3.5mm Aux input jack FCC NOTE: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Operational Description Host receive contains the following main components and functions: after U3 (AV-Link Rx-V0 2.4 G module) receive treatment of audio signal transmission lines through to R6 potentiometer for sound volume after U1 (JRC4558) to power amplifier amplification U2 (HT6871) power output to the speaker; IC2 (EUP8054) for lithium battery, IC1 (EUP2410) to boost circuit circuit to 5 V booster as power supply. RF Module Operational Principle 1. CPU,AWA8810 is a low power 2.4GHz wireless digital audio SOC embedded many valuable IP’s including 2.4GHz GFSK RF transceiver, LDO, MCU. It needs an external 24MHz crystal for reference frequency. 2. E2PROM, 24C128,131072 bits of serial electrically erasable and programmable read_only memory(EEPROM) organized as 16384 words of 8 bits each.The device is optimized for use in many industrial and commercial applications where low-power operation are essential. 3. Audio codec ES8331，It is a high performance,low power codec,it consists of 2-ch ADC,2-ch DAC,microphone amplifier,headphone amplifier,digital sound effects,and analog mixing and gain functions. 4. Power Management, It is a complete constant-current/constantvoltage linear charger for single cell lithium-ion batteries. 5. ANTENNA, The antenna is typically fed from the end of the monopole section by a plated through-hole via which is in turn connected to the RF output on the 2.4GHz band.
