Warning: Do no try to recharge the non-rechargeable batteries, or the batteries would explode! The speakers’ DC 12V jack is for charging rechargeable batteries and powering the speaker. 1. Turn off the speaker. 2. Remove the battery cover. 3. Slide ON/OFF inside the battery compartment to ON. 4. Insert eight C rechargeable batteries in the battery compartment, matching the polarity symbols (+ and -) marked inside. 5. Connect one end of the 12V DC adaptor to the DC 12V jack and plug the other end to a standard AC outlet. 6. When charging is completed, unplug the DC adaptor from the power source, and disconnect it form the speaker’s DC jack. recharging Ni-Cd or Ni-MH batteries transmitterspeaker You can connect your audio source (such as MP3, CD and DVD) to the transmitter with the supplied RCA cable. 1. Connect the RCA cable’s color jacks to your transmitter by matching the color. 2. Plug the other ends into your audio source’s output jacks. If the output jack of your audio source is 3.5mm or 6.3mm, connect the RCA cable to the 3.5mm plug adaptor or/and 6.3mm plug adapter for the connection. connecting to y0ur audio source You can power the speaker with the 12V DC adaptor. To power the speaker with AC power, connect one end of the 12V DC adapter to the receiver, then plug the other end into a standard AC outlet. The green led on the transmitter turns on when its built- in Automatic Level Detection circuit detects the music or signal from the audio source. When the audio source stops for more than 30 seconds, the transmitter will automatically shut down and enter the standby mode. powering the speaker with AC power 1. Lift up the battery cover on the bottom of the speaker. 2. If the batteries are non-recharg…

Circuit Description of 40-1475 900MHz Wireless Indoor/Outdoor Mono Speaker Issued by: Addy 09/26/05Revision APage 2 of 10 TRANSMIT SECTION Compressor The audio signal from RCA jack (JK1 & JK2) feeds to the compressor U1. After the audio signal has been compressed, it delivers to the buffer amplifier (Q6) and pre-emphasis by a RC network (C2, R24 and R25). Then, the signal is routed to the voltage control oscillator (VCO) section. Auto Level Control (ALC) To prevent the transmitter from over-modulation, U1 provided a built-in ALC circuitry. The ALC attack time and recovery time is control by C6. The ALC starting point is controlled by the potential divider R1 and R2. VOX detection To detect if there is any signal presenting at the input terminal for the transmitting purpose, a VOX detection circuitry is built with Q5 and Q7. It amplifies the signal from the compressor output (pin 12) and direct feeds to the pin 11 of the MCU. When there is signal presenting at pin 11 of the MCU, it’s output pin 20 goes high. It turns on the power supply of the RF transmitter section. After that it polls the data to the phase lock loop (PLL) IC U401 and starts the transmission. Oscillator and Modulator The oscillation frequency is derived from a single 16MHz crystal by means of a phase locked loop (PLL). The voltage control oscillator (VCO) is formed by Q404; L404 and D401.Frequency modulation is provided by a varactor diode VD401 when the audio signal is applied through the resistor R460. RF Power Amplifier and switching circuitry Q405 and Q406 are adopted as the power amplifier to drive the antenna through the low pass filter (L401, L402, C402, C403 and C450).
