(Supported audio format: MP3 files) 3 SD Card Slot - When a TF (MicroSD) card is inserted in place, music or other audio sources on the card will be automatically played. (Supported audio format: MP3 files) 4 AUX Input - When you connect an audio cable (not supplied) via the AUX input, the speaker plays the audio signal from the connected device. In this case, the control operation is carried out exclusively through the connected device and not via the speaker. -VOL/OFF - Decrease the volume level (Control Range: 30 ~ 10). Press to pause/OFF the play when the volume is at level 10. [Short Press]: Reduce the volume level one by one. 5 Display Screen - Indicate the working status in different modes. Notes: The volume meter bars at the both sides of display screen will be flashing along with the play under different modes and will go out when the speaker is in standby mode or pausing. 23 1 When the speaker is powered ON, the default mode is FM Radio. It will automatically boardcast the first station starting from 87.5 MHz or the radio station that previously stayed on. Control Specification ON/VOL+ - Increase the volume level (Control Range: 10 ~ 30). Press to resume/ON the play if the speaker is pausing. [Short Press]: Increase the volume level one by one. [Long Press]: The volume will be up until releasing the button or to the highest level. 6 [Long Press]: The volume will be down until releasing the button or to the lowest level. MODE SELECTION : FM Radio and Bluetooth Connection. [Step 1]: Press button & together and hold them for 2 seconds to switch to Bluetooth mode and it will come out a sound signal as well as blinking characters “ ” display on the screen for notification. [Step 2]: On your smart phone or other Bluetooth devices, enable Bluetooth function and search for nearby Bluetooth device to pair with. Select “JQ-BT ” from the list of available devices on the screen of your Bluetooth device. It may take a moment before your device detects the speaker and is available in the list. When successfully paired, a short prompt will be heard and the characters “ ” on the screen will change from blinking to always on. [Step 3]: Music or audio streams from the connected device will now be played through the speaker. ATTN: • Make sure the devices are within Bluetooth range (within 10 Meters). • The speaker can remember multiple Bluetooth devices and will always try to reconnect to the last device it was paired with. • To reconnect to a different device, turn off Bluetooth on unwanted devices, then access the Bluetooth Settings on the device you wish to use and select “JQ-BT ” to reconnect to the speaker. • Multiple Bluetooth devices cannot be played back at the same time. 6 5 23 1 7 - Decrease the FM frequency or Skip to previous track/song.

Limit and Guidelines on Exposure to Electromagnetic Fields According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D01 General RF Exposure Guidance v06, Mobile Portable RF Exposure, no SAR required if power is lower than the flowing threshold: 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 calculation25 • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below 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 according to 5) in section 4.1 is applied to determine SAR test exclusion. 3.
