CONNECTING THE VGP30 TO A PBX
The VGP30 has one 3.5mm jack output for connexion to the MOH input of the PBX. An audio cable, terminated with a
3.5mm jack on one end and with an RCA/phono plug on the other end is supplied with the unit for this purpose.
See connection diagram below.
First make sure that the SD memory card is inserted and locked into the slot on the right side of the front panel. Now
connect the power supply adapter supplied with the unit into the power input on the VGP30 and into the mains socket
on the other end. The VGP30 has been designed to work with a power adapter providing between 7 to 12VDC (9VDC).
Now switch the power on by turning up the volume knob in the centre of the front panel, to the left. (To switch the power
Off it should be turned to the right until it clicks) As soon as the power is switched on the LED window located in the top
panel of the player will light up and will display red strips rotating in the LED window for a second and then display a
track number e.g.,
“001”
or any other track number.
If no number appears on the LED screen it could mean either of the following :
a) The audio file names are not preceeded with a three-digit number (e.g.
“001”
...or
” AL”
)
b) There are no audio files on the SD card or files which can be recognised by the player.
c) The SD card has not been inserted deep enough to lock itself in the card slot. (Please do not use excessive force)
When the VGP30 has started reading the SD card, switch on the built-in loudspeaker, using the on/off switch located to
the left of the front panel and adjust the volume output located in the middle of the front panel. The audio level going
towards the MOH input of a PBX is adjusted with the same volume control. To adjust the audio level output which will be
heard by correspondents when being put on-hold, there is a simple method: The person whom ajusts the audio level of
the VGP30 should be called on a cell phone and then be put on-hold. Switch the Monitor switch on the VGP30 to OFF
so that the MOH will only be heard through the speaker of the cell phone. The person using the cell phone will then be
able to optimise the audio level output.

SELECTING YOUR APPLICATION
There are two different kinds of audio ouputs on the front of the VGP30: The first is labelled “To PBX audio” with a 3.5mm
jack input and its volume control knob, in the middle of the front panel. The other is located on the left hand side of the
front panel, and has two RJ-9 sockets which will allow a desktop phone to be connected to the VGP30. The volume output
control knob is located next to the RJ-9 sockets.
The VGP30 will not be able to work in both ways simultaneously, and you should therefore choose between connecting
directly to a desktop phone or to the audio port of a PBX.
