There is radio interference

The DSP420 is a digital audio and computing device which has

been designed to very high standards of electromagnetic

compatibility.

If this equipment does cause or suffer from interference to/from

radio or television reception then the following measures should

be tried:

❍

Reorient the receiving aerial (or antenna) or route the antenna

cable of the receiver as far as possible from the DSP420 and

its cabling.

❍

Ensure that the receiver uses well-screened antenna cable.

❍

Relocate the receiver with respect to the DSP420.

❍

Connect the receiver and this product to different AC outlets.

❍

If the problem persists contact your dealer.

Configuring the DSP420 does not
have any effect

Make sure that you are configuring the DSP420 used as the

master digital loudspeaker in the system. This determines the

configuration of all digital loudspeakers in the system.

Meridian Configuration program
repeatedly fails to talk to the
loudspeaker

❍

Check that you have selected a COMMS port.

❍

Check that no other program currently running is using the

COMMS port.

❍

Check that it is connected correctly.

❍

Turn off the DSP420 for a few seconds and turn back on, then

retry.

❍

Quit from all other programs and retry.

❍

Reboot the computer and retry.

❍

Ensure you are using the serial lead supplied with the product,

or a null modem cable.

❍

If you are using a notebook computer try turning off the

screensaver or power management software.
