Installing APP 4. Connecting speaker under WiFi mode -5- A, Network Connection Enter WLAN setting of your device, and connect your network Turn on the speaker, you will see blue light (please kindly wait, it takes around 8s to turn on WiFi function) Enter our APP; click “Add Device” to connect speakers with your network: Press WPS on the speaker, you will hear “WiFi Searching”, then click “next” on APP Click or slide right to play online music or downloaded music as you want Add more speakers: press “+”(on right top of APP), then follow the APP advise. Do this again to add the third or more speakers. Click the setting key" " in APP to rename the speaker or other setting Play allPlay allPlay all change channel same music Speakers play different music add device -6- B. Direct Connection (This is used when there is no network, such as outdoor activity Remarks: The first speaker you connected just like the router, if you turn off the speaker, other speakers will be disconnected. If you turn off other speakers, the rest ones remain work. The possible reasons of failure of adding devices: 1. The most possible reason is that your smartphone connect with the WiFi router which is 2.4G, then device can't receive the request of connection sent from smartphone. 2. If you have a band router (2.4Gplease set the 2.4G password , then maybe connectable, maybe not, depends on the routers. 3. If the router set Enterprise WPA will fail to connect, as we don’t support Enterprise WPA. 4. Belows setting on router will also result in failing to add device: a) If the IP address is assigned statically b) If there is MAC address limitation, only specific MAC address could connect c) The router is hide 5. Some routers has maximum connection, when exceed the maximum, will fail to add device. 6. Network is too bad, may be successful after trying many times. Turn on the speaker, you will see blue light Enter WLAN setting of your device and turn on WLAN Search the WiFi name of speaker “WiFi Speaker”, connect. Enter APP, play music or add more speakers -7- 6. Bluetooth Connection Press mode switch key“ ”to change the mode from WiFi to Bluetooth . Then will see blue light“ ” flash . The speaker is in Bluetooth mode and waiting for connection. Navigate the Bluetooth function of your device (Select “Set Up” Bluetooth or turn “ON” Bluetooth) Select “Search” or “Discover” devices Select Bluetooth “iChocolate” If required, type the password or PIN 0000 After completing the steps above, a message on your device will appear confirming that your device is now paired/connected. In case of unsuccessful pairing, turn off the speaker and restart it. 5. Mode Switch When turn on speaker, it will be WiFi Mode automatically 1. The first time press “ ”, it will turn to Bluetooth mode 2. The second time press it, will turn to Line-in mode 3. The third time press it, will turn to WiFi mode Each time press the switch key “ ”, mode will change as aboved steps. 1. 2. 3. 4. -8- 6. 1 NFC Connection NFC: Near Field Communication, is a set of standard for smartphone and this speaker to establish Bluetooth radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. Please activate the NFC function (subjects to device own setting) function of your Bluetooth device. Bring your Bluetooth device close to speaker, as above picture. Bluetooth device will ask you whether you want to pair the speaker, confirm by “Yes” or “OK”, then the pairing process is completed. 6.2 Microphone Usage When a phone call comes in, you could talk through the microphone on speaker. Tips: When you make a call from your mobile phone the call will (subject to phone settings) automatically transfer to the speaker. -9- 7. Cable connection (Line-in) 3.5mm stereo jack 8.

FCC ID : 2AFSS-WIFISPK RF EXPOSURE EVALUATION METHOD FCC ID:2AFSS-WIFISPK SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR,where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Maximum measured transmitter power.
