When the blue and red lights flash, the SleepBuddy is powered on. Search for the Bluetooth device named XSLEE-3, connect to it and play music. The device will automatically shut down30 minutes after the Bluetooth connection is disconnected, or you canpress and hold the power button for 2 seconds to turn it off manually. The indicator light will turn off accordingly SleepBuddy Operation Instructions 2.A short press of "4" increases the volume; a long press skips to the previous track; a double press enables a 60-minute timer with the blue indicator light on, and another double press disables the timer with the blue indicator light off 3.A short press of "6" decreases the volume; a long press skips to the next track; a double press enables a 30-minute timer with the blue indicator light on, and another double press disables the timer with the blue indicator light off. 4.TF卡按真确的方向插入TF卡槽，即可实现自 动切入TF卡播放模式。也可双击“5"键切入。 4.Insert the TF card into the TF card slot in the correct direction to automatically switch to TF card playback mode. You can also double press the "5" button to switch to this mode. Compatible with any pillow, the SleepBuddy transmits vibrations to the pillow based on the bone conduction principle. The pillow then acts as a sound-emitting medium, enabling the music playback function. Usage Scenario Troubleshooting Failure to power on Check if the SleepBuddy is fully charged and whether the power button has been pressed and held for more than 3 seconds Check if the SleepBuddy’s red and blue indicator lights are flashing alternately. If the lights are off, verify whether it is connected to another device or powered on. To connect it to your target device, simply disconnect it from any other paired devices. Bluetooth connection failure Set your phone volume to around 30% for sleep mode , ensuring no sound is heard by others nearby for a safe and private experience. Volumes above 30% activate entertainment mode Excessive sound leakage Check if your source device (e.g., mobile phone) has a Bluetooth version of 4.0 or above, as older versions may result in a shorter Bluetooth reception range. Short Bluetooth reception range Operating Instructions Position the SleepBuddy at the bottom of the pillow with the silicone side facing down. Power on the device and connect via Bluetooth for normal use, with the best experience when sleeping on your side. Correct Placement Sleep Mode with private audio and no sound leakage at volume below 30%; Hi-Fi Mode with powerful immersive audio at volume from 30% to 100%. Usage Modes For the best experience, place the SleepBuddy near the center of the pillow; the optimal effect is achieved when sleeping on your side with your ear aligned with the center of the device. Optimal Performance Thank you for your purchase and kind support.
