Keep at least 9 inches/20cm between the device and the pacemaker. For more information consult your doctor. • Do not throw the device into an open fire. • Do not exceed the voltage specified on the power supply unit (5V). Exceeding the voltage may destroy the device. • If you use the BluNote + Chat™ for wireless mobile phone calls in your car, please obey all cell phone and driving laws in your area. • Do not open the unit. Doing so will invalidate the guarantee. • Permanent hearing loss may occur if you use the device at high volume. You can adapt over time to a higher volume, which may Precautions 4 • Do not use the BluNote + Chat™ near water, such as a sink or bath tub, or in a wet area. • Do not use the BluNote + Chat™ during an electrical storm or near a gas leak or vapors that could be ignited. Please Note: Improper use will invalidate the guarantee! In some countries there may be restrictions to the use of Bluetooth® devices. Please make enquiries with the authorities responsible. 1. Powering your BluNote + Chat™ Before you can pair your BluNote + Chat™ to a Bluetooth® device, you must power it either by plugging in the AC power adapter or by using Precautions 5 the rechargeable Li Ion Battery. In order to run on the battery, you must first charge it. This will take about 3 hours the first time; subsequent charging times will vary on the battery life left. • Use only original accessories. This will avoid potential damage to health or property and ensure compliance with all relevant regulations. sound normal but can be damaging to your hearing. Set your volume to a safe level. If you experience ringing in your ears, reduce the volume or discontinue use of your system. 2. Powering On/Off There is an main On/Off switch at the back of the unit. When you turn the switch to the On position The BluNote + Chat will automatically be in pairing mode. Pairing is the process of two Bluetooth® compatible devices linking or communicating with one another. A mobile phone identifies a Bluetooth® device and uses a password or PIN to establish pairing. This process allows only a verified device to connect to your mobile phone, ensuring security. The pairing process is described below. The is a Power Icon on the top of the unit. Touching this icon puts the unit in the equivalent of "sleep mode". The lights on the top will dim but there will be a red line that flashes every 5 seconds to remind you it's in Stand By mode. You'll be able to resume playing music just by touching any Icon on the top of the unit. Keep in mind that this mode will discharge your battery more rapidly, if you are running from battery and not plugged in. 3. Pairing the BluNote + Chat™ with a Bluetooth® enabled Mobile Phone or other device IMPORTANT: When pairing the BluNote + Chat™ to a Bluetooth® device, pair as "speaker" or "wireless speaker". Your device may list different pairing options: choose the one that most closely fits "speaker". If your Bluetooth® enabled device does not list a speaker option, please make sure your device is: 1) A2DP compatible, and, 2) has the latest Bluetooth® driver available for your device installed. You may need to check with your device's manufacturer for compatibility. The only exception is the MacBook Pro which only has the "Headset" option available. Check the Spracht website for more information. If you need assistance with pairing, please User Guide 6 call Spracht Customer Service at +1 650-215-7500, Monday to Friday 9AM-6PM Pacific time, or email [email protected]. • Turn the switch at the back of the BluNote + Chat™ to On. • Power on your Bluetooth® enabled mobile phone or other device. • Activate Bluetooth® on your Bluetooth® enabled device and search for Bluetooth® devices (if in doubt please refer to your device's user manual for details on activating Bluetooth). • Follow your device’s instruction guide to connect to a Bluetooth® device. Typically, you will click on a Bluetooth® icon and click “Discover device.” • Your A2DP Bluetooth® device should give you an option to choose to pair your BluNote + Chat™ as a "Headset" or a "Speaker". The preferred pairing option is "Speaker". NOTE: Choosing the "Headset" option will enable you to accept calls, however, it may make your music sound distorted. If you do not see a "Speaker" option, please check with your device's manufacturer for compatibility. • Your mobile phone should find the BluNote + Chat™ which is displayed as “BluNote + Chat”. • Click on “BluNote + Chat” and click “OK” if your phone prompts you to confirm. • If your device then prompts you to enter a PIN or password, enter: 0000 • If the pairing is successful, your device will indicate a successful pair and "Pair On" will scroll through the LED display for 5 seconds. • Depending on the software concerned, your device may then CONNECT automatically to the BluNote + Chat™. You will then see the message CONNECTED on your device's display. In…

YG-209M module consist of Bluetooth chip BC57E687,8MB Flash and 16MHz crystal, after external power working, IO controlling drive Bluetooth chip. The software stored in flash control the bluetooth chip transmitting or receiving data. When the device paired with other wireless devices,they could communicate with each other following the Bluetooth protocol. The working frequency range of RF module YG-209M is setted from 2402MHz to 2480MHz, the sepeartion is 1MHz and there are 79 channels in total. The working procedures are: a. When power on, the Bluetooth speaker will loop scan the whole frenquency until a connection command from the transmitter is received. b. The Bluetooth speaker transmit a response signal. c. The transmitter receive the response signal and recognize it, then send a connection command to establish the connection. d. After the connection establish successfully, the data transmission is beginning. At the same time, the transmitter and Bluetooth speaker will shift frequencies in synchronization per a same pseudo randomly ordered list of hopping frequencies, the hopping rate is 1600 times per second. The Bluetooth speaker conform to the criteria in FCC Public Notice DA 00-705. e. The bandwidth of the Bluetooth speaker, which is set to a fixed width by the software, match the hopping channel bandwidth of their corresponding transmitter.
