Increasing Internal Loudspeaker Volume
The internal loudspeaker is a low power speaker. Volume controls have to be
set to maximum values to hear sound correctly.
If a customer requires more power, the headset should be used (using the
headset automatically disables the internal speaker) or an external speaker
should be connected to the rear connectors.
To set the volume control to maximum:
1 Double-click on the Sound icon.
2 Set Master volume, Wave Out balance, and Internal FM volume to maximum.
Check that all balances are set at the medium positions.
