During charging, the indicating LED lights up red in color and all earphone function will be turned off automatically. When the charging is completed, the earphone indicator (Red LED) turns off and the adapter can be removed from the earphone and AC socket. Low voltage indication During normal power consumption, the voltage may gradually drop to 3.3 V, the indicating light (Red LED) flashes once every 4 seconds. When the voltage drops to 3.0V, the indicating light (Red LED) flashes once every 4 seconds, and the earphone will power down automatically after 30 seconds. When the earphone detects a low voltage, please re-charging device immediately in order to maintain the proper battery quality. Turn on and Turn off Tu r n o n Press MFB button for 3 seconds, you will hear tone from the speaker and the LED light for 3 seconds. Earphone will go into stand-by mode. Turn off Press MFB button for 3 seconds you will hear tone from the speaker and the Led light for 6 Seconds. Earphone will be turned the power off. It also disconnect with paired device. Toggle the buzzer (at waiting mode) Turn off Press V+ or V- for 3 seconds, you will hear a “beeping” sound twice. Then, incoming call signaled by a buzzer sound is deactivated. Tu r n o n Press V+ or V- for 3 seconds, you will hear a “beeping” sound once. Then, incoming call signaled by a buzzer sound is activated . Pairing the Bluetooth earphone with Mobile Phone Pairing with the mobile phone Only connect the Mobile Phone supported with Bluetooth function. Put the Mobile Phone and the Bluetooth stereo earphone in an observable distance within 1 meter between them. Make sure the Bluetooth earphone is in “off” status. Press and hold the MFB for 6 seconds until the earphone LED flashes red and blue alternately. It’s now ready for paring. Activate the Bluetooth function built-in with your mobile phone (referring to your mobile phone user manual). The mobile phone will search for all accessible Bluetooth devices. Then select “Joybee ET50” from the Bluetooth device’s name list shown on mobile phone display, and confirm your selection accordingly. Enter the password “0000”to confirm it. Your Bluetooth earphone is now paired with your mobile phone. Zhuhai Sunda Technologhy Co.,Ltd Page 3 of 6 Joybee ET50 Product Specification and User Guide After pairing, you will hear a long tone from the earphone speaker, meanwhile, the indicator light of the phone (Blue LED) will flash thrice slowly and continue to flash once every 4 seconds. If pairing uncompleted after 2 minutes, the earphone will power off automatically. So you have to repeat the mentioned steps for pairing your earphone again. Return to the main menu or “home” of your mobile phone; make sure there is no obstacle between your earphone and mobile phone in an effective distance of 10 meters, now the earphone is paired successfully and ready for answering call or listening to playback music. Answering a call To answer a call, wait for the Bluetooth stereo earphone to ring, then short press the MFB. Ending a call During conversation, short press the MFB to end a call. Reject a call When you hear the beep from the speaker or the “beep” from the buzzer, press and hold either V+ or V- button for 3 seconds until a short beeping sound is heard from the earphone. Voice dialing If you mobile phone is voice dialing enabled, under the stand-by mode, press the MFB and when you hear a beeping sound, say your required name to response the voice tag. IMPORTANT: Please make sure to record voice tag into the mobile phone before you using the voice dialing function. This function is only applicable to mobile phone with Bluetooth hands-free profile. Please refer to your mobile phone user guide for detailed voice dialing operation. Last number Re-dialing Under stand-by mode, short press the MFB on your stereo earphone twice. Your mobile phone will redial the last number automatically. Interchanging You may toggle your conversation between your stereo earphone and your mobile phone very conveniently. During talk time, press and hold the V+ or V- button for 3 seconds, your conversation will be directed to mobile phone. By short pressing the MFB, your conversation will be taken place with stereo earphone again. Listening to music While enjoying the music, short press the MFB to pause the music and short press the MFB again to play the music again. (This function is only applicable to Bluetooth stereo mobile phone with the A/V profile. Please refer to your mobile phone user guide for detailed…

The input signal maybe from either a microphone or line. The amplified signal is then digitized by a ADC . This device transmits and receives signal with A2DP. Firstly the microphone sampling voice and transform thin electrical signal and coupling it to Bluetooth module amplifier circuit. C9C10C11 and C12 should be 0.1Uf. R17 sets the microphone load impedance is normally 2.2k.Vbias should be chosen to suit the microphone and have sufficient low noise. It may be filtering the output of a PIO line. The microphone should be biased as shown in figure1.1. Figure 1.1 Speak Output Stage The digital data is converted to an analogue value by a DAC, then it is filtered prior to amplification by the output amplifier and it is available as a differential signal between SPK_R and SPK_L. The out amplifier is capable of driving a speaker directly if its impedance is greater than or equal to 8w. Figure 1.2 Joybee ET50 Specification Charging Stage Figure 1.3
