How To Play 1.Install a 9V battery cell or plug the AC/DC adaptor which come with the package to the transmitter unit (if both 9V battery cell and AC/DC adaptor are installed, only the power of the AC/DC adaptor is used, the path of the battery cell will automatically cut off). 2.Install 4 pcs AA battery cells to the receiver unit. 3.Plug the ear phone jack to a “walkman” or “discman”. 4.Push the power button to power on the transmitter unit, the LED indicator will turn on. 5.Select a channel (CH-A or CH-B) on the transmitter unit for transmission. 6.Slide the channel switch on the receiver unit to select the channel which same as the transmitter unit. 7.Slide the “OFF LO HI” switch of the receiver unit to “LO” or “HI” position (“LO” is low volume, “HI” is high volume) to turn on the unit, the unit will automatically go to working mode, the LED indicator will turn on, the audio music will be hear from the speaker. 8.The receiver unit will continue to work for one hour with +/- 15 minutes tolerance, after that the unit will automatically shut down (go to sleep mode, the music will stop), the LED indicator will turn off. 9.Press the re-trigger button to trigger the receiver unit to working mode again, the unit will then work for one hour and automatically shut down (go to sleep mode). 10.Press the re-trigger button of the receiver unit when the unit is in working mode, the one hour timer will be reset, the one hour timer will be re-start to count again (for example the receiver unit start to work on 9:00, at 9:30 press the re-trigger button, the unit will be automatically go to sleep mode on 10:30). Caution 1.Do not mix old and new batteries. 2.Do not mix alkaline, standard (carbon-zinc), or rechargeable batteries. 3.Only batteries of same or equivalent type as recommend are to be used. 4.Batteries are to be installed with correct polarity. 5.Exhausted batteries are to be removed from the toy. 6.The power supply terminals are not to be short-circuited. 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 no 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 receiver. -Correct the equipment into an outlet on a circuit different from that to which the receiver is needed. -Consult the dealer or an experienced radio/TV technician for help.

Frequency Alignment Procedure of #630211 Lulla Bear 1. Transmitter a) Connect the transmitter unit to the DC power supply (+9VDC); b) Use the Spectrum Analyzer to monitor the frequency; c) Slide the channel selector to CH-A position, adjust the coil T2 on the PCB until the frequency reading on the Spectrum Analyzer is 49.845MHz +/-0.005MHz; d) Slide the channel selector to CH-B position, adjust the coil T3 on the PCB until the frequency reading on the Spectrum Analyzer is 49.865MHz +/-0.005MHz; e) Use the wax to seal and fix the coil T2 & T3. 2. Receiver a) Connect the receiver unit to the DC power supply (+6.0VDC); b) Connect a frequency counter across R2 to monitor the frequency; c) Slide the channel selector to CH-B position, the frequency reading on the frequency counter will be 49.79MHz +/-0.005MHz [49.865MHz – 0.075MHz (local oscillator) = 49.79MHz]; d) Slide the channel selector to CH-A position, adjust the coil L9 on the PCB until the frequency reading on the frequency counter is 49.77MHz +/-0.005MHz [49.845MHz – 0.075MHz (local oscillator) = 49.77MHz]; e) Use the wax to seal and fix the coil L9.

#630211 Lulla Bear Technical Description The product consists of 2 parts, the transmitter unit and receiver unit. The transmitter unit is connected to the music player (“walkman” or “discman”) to accept audio music, and send the music to the receiver unit via the RF channel. The receiver unit demodulate the RF signal from the transmitter unit, and output to the speaker. The transmitter unit is either operated with 1 x 9V battery cells or AC/DC adaptor. When the transmitter unit is powered on and connected to the music player (“walkman” or “discman”), The transmitter unit will modulate the audio music with the carrier signal. The carrier signal is selected by the channel selector (CH-A is 49.845MHz, CH-B is 49.865MHz), the mixed signal (carrier signal and audio music) is sent out via the antenna. The signal is emitted continuously while the transmitter unit is powered on. The receiver unit is either operated with 4 x 1.5V AA battery cells. When the power switch is turned on, the unit is ready to receive the RF signal. If the transmitter unit is powered on and connected to the music player, there will be a RF signal output from the antenna of the transmitter unit. The receiver unit will receive the RF signal, and recover the original music by means of demodulation. At last the audio music is output to the speaker. There is a timer IC inside the receiver unit, which control the working period (one hour timer) of the receiver unit. The receiver unit will automatically go to working mode for 1 hour when the unit is powered on, after that, the unit will go to sleep mode. The receiver unit will resume to work when the re-trigger button is pressed.
