Media player
The H25B has an internal USB mp3 player, FM tuner and Bluetooth receiver, which are selected by pressing the MODE button (2)
Insert a USB drive with mp3 files stored on it to the USB A socket (5) to start playback. If playback does not start, press the MODE
button repeatedly until it is in USB mode. Track navigation is controlled via buttons for Next Track, Play/Pause, Previous Track (1, 3, 4)
The FM tuner function is another option accessible by pressing the MODE button until a radio station can be heard. If no stations are
tuned, there may be just white noise and the auto-tuning process will need to be completed first. To do this, press and hold the
Play/Pause button (3) for 3 seconds and the auto-tuning process will start (the LED inside the USB port will flash more rapidly).
The auto-tuning process may be stopped on a particular station by briefly pressing the Play/Pause button again.
Once tuned in, stepping through the radio stations is possible using the Next Track and Previous Track buttons (1, 4).
The H25B also has an inbuilt Bluetooth receiver which can be activated by pressing the MODE button (2) to switch from USB mode to
Bluetooth mode. Search for “LS101”device ID in your smart phone Bluetooth menu and select to pair to play tracks wirelessly from the
smart phone to the H25B. An audible notification is played when a smart phone or other sending device is connected. Once paired, the
device can be automatically re-connected when the H25B is in Bluetooth mode and the device is within reception range.
Track navigation is controlled via buttons for Next Track, Play/Pause, Previous Track (1, 3, 4)
In any of the Bluetooth, USB or FM modes pressing and holding the Next Track and Previous Track buttons (1, 4) will increase or
decrease the output level of the media player.
