3) To play music* from a TF or microSD card, simply insert a card containing MP3 music into the slot
labeled "TF." You will hear a voice announce "Play by SD card." (See Controlling Music Playback
below for more details.)
4) To play music from a wired connection, connect the 3.5mm plug from the proprietary (included)
USB/3.5mm/micro-USB connector to your music device line-out or headphone recepticle and the
micro-USB end into the back of the AS313BT portable speaker system. Then select "Line-in Mode"
by cycleing the mode ❶button.
*Music played via microSD or USB must be in .MP3 format.
Controlling Music Playback
For the line-in mode, you must control the music playback from your device. You can hold down
buttons ❷or ❸to adjust the volume.
For all other modes, you can also control the song selection and volume from the buttons on top of the
unit. Use buttons ❷and ❸to jump to previous and next songs, respectively. Hold down buttons ❷or
❸to adjust the volume. Use the Pause button (❹) to temporarily pause the song being played. Note:
The volume control on your device will also impact the volume coming out of the speaker. For the
highest quality sound, set the volume on your source device to a moderate level (not as loud as it gets).
Note: If you have both a USB flash drive and a microSD/TF card inserted, you can jump from one to the
other via mode. As well, when finished playing songs from one of the media, the AS313BT will switch to
the other media type for the next song and continue automatically from there.
Phone calls
This speaker system contains a built-in microphone and also operates as a speakerphone for your
smartphone when in Bluetooth mode. If a call comes in while listening to music, you will hear a caller ID
announcement (if available) followed by a ring sound. Press the Pause/Phone (❹) button to pick up
the call. Speak normally. To end the call, press the Pause/Phone (❹) button again. For best results,
speak at a close distance from the AS313BT speaker system.
