Connecting to a Computer:

The player stays in the phone room, You may connect the USB adapter to a
PC and access / update SD card via the USB adapter. Connecting the player
itself to a PC USB port provides playback only, SD card can not be accessed
or updated this way.

When you connect the USB adapter to PC and insert the SD card into it, a
status LED turns ON and the USB adapter will be detected as “Removable
Disk” , when you open “My Computer” or “Windows Explorer”

Transferring files into SD card:

Select the file you want to transfer to the SD card in the USB adapter and
drag-and-drop it into the “Removable Disk” that represents this device (right
click on the file, copy, move the mouse to the “Removable Disk” , right click
there and paste)

The player will play all the .mp3 files one by one before it auto repeats from
the 1


file, so if you only need it to play one .mp3 file then just keep one .mp3

file in the SD card, i.e. move or delete the extra files you do not want to play
from the SD card.

When the file is being transferred to SD card allow several seconds for it to
finish transferring before removing the SD card from the USB adapter.

To test the audio:

the provided earphone can be used to hear the

audio playback any time, To do this connect it directly into Audio Out jack
on the player, if the player is off turn it ON, (blue LED blinking) If you
have not installed the player to your MOH jack and power adapter yet,
There is enough power in the player itself to let you play and test the
audio for a few minutes, connect the player to power and to the MOH port

it, simply “press in” the old SD card so it snaps
out, then insert the new SD card and make sure it
snaps in, the playback automatically starts.
