Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. Cleaning When the apparatus needs a cleaning, you can blow off dust from the apparatus with a blower or clean with rag etc. Don't use solvents such as benzol, alcohol, or other fluids with very strong volatility and flammability for cleaning the apparatus body. Clean only with dry cloth. Servicing Refer all servicing to qualified personnel. To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. 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. CSB-20BT/40BT (MASTER) TO SET-UP 2 LOUDSPEAKERS (STEREO) RIGHT AUDIO SIGNAL STEREO AUDIO SIGNAL Bluetooth audio device CSB-20BT/40BT (SLAVE) Note: The loudspeaker that is connected to your source device is the "master"; the linked loudspeaker is the "slave". The source device sends its signal to the master, and the master relays the signal to the slave. 1.Press and hold the PAIR BUTTOM for 3 seconds on both loudspeakers first. BT RED LEDs will flash and you will hear a tone (beep). wait 10 seconds. 2.Wait for MASTER and SLAVE to link. When successfully linked, the tones will stop and BT RED LEDs will light solid on both speakers. 3.Choose a MASTER loudspeaker. MASTER can be either loudspeaker. Be sure to choose only one. The remaining speaker will be the SLAVE. 4.Press and release PAIR BUTTON on the MASTER loudspeaker only. You should hear a tone (beep) ; the PAIR BLUE LED will flash. 5.Select SEIKAKU BT2.1ONS on your Bluetooth audio device. (iphone, ipad,bluetooth adapter etc.) You should enter the password"2013", When your device's Bluetooth will pair. 2 7

11 INDOORS MINI SPEAKER BLOCK DIAGRAM INTRODUCTION CSB-20BT/40BT series is designed for indoor installation and most public address system. It provides quality performance,furthermore, we offer optional metal rotatable mounting bracket, thus you can install CSB speaker on wall easily. This new compact speaker series meet every demands for restaurants, supermarket, shopping mall, pubs, and so on. The wireless loudspeakers will remember their pairing and linking settings even after they are powered off. When you turn the loudspeakers back on, they will automatically reconnect to each other. When the connections are re-established between the loudspeakers, the LINK LEDs will light continuously. Enjoy your CSB series speaker cabinet and make sure that read this manual carefully before operation.

12 INDOORS MINI SPEAKER Note: Commercial audio installation system must conform to local building laws. When install speaker on wall or ceiling, please consult a building constructer with a license or a professional engineer. The corporation won't be responsible for the improper installation or damage because of not conforming to installation description. Installation procedure of CS-2 bracket is very simple and convenient, the appearance is pleasing to the eye. INSTALLATION DESCRIPTION (3) Step 1: Fasten the CS-2 bracket(1) on the wall with screws. The wall material must support the weight of the cabinet. Step 2: Place the body of cabinet in CS-2 bracket(2) and lock the screws tightly Step 3: Use screw (3) lock CS-2 bracket(1) and CS-2 bracket(2) and use steel rope (4) to connect two brackets. INDOOR INSTALLATION DESCRIPTION: CSB series speakers are designed specially for fixing and using in different circumstances. The property of speakers may be different due to different circumstances. There is an acoustic surface (wall, floor and ceiling) in a closed room, so the acoustic indoor will turn complex. When acoustic wave hits the surface, a part of acoustic energy is reflected, and others are absorbed. Reflection and absorption are depending on the frequencies of acoustic wave and angle of hitting surface. When operate the cabinet, both man and furniture can absorb the acoustic energy. Please note the position of man and furniture when installing. Reverberation is the results of the reflected acoustic wave continue bouncing between the surfaces. Every reflection will loss the energy. When the acoustic hit the reflection surface, the room will be filled with random reflected acoustic wave. The music and address will be complex. It is recommended that install more speakers and make the volume of speakers lower to reduce the reverberation in high reverberating room. (Please see figure 5B) (1) (2) ONE LOUD SPEAKER (figure5a) MULTIPLE QUIET SPEAKERS (figure5b) Speaker coverage range Direct the center axile of the speaker to the flat surface of receiving area. The speakers of series can spread the speaker tone to all the directions at the axile of. If you use the speakers in large room, you can divide the room to some zones. Then decide the installing location of the speakers. (Please see figure 6) (4) (eg:csb-20bt) HORIZONTAL (figure6) VERTICAL 4 5
