If problems are experienced, please read through the symptom topics below in order
to resolve the problem. After doing so, if you still need to, contact Technical Support
at
http://www.tvone.com/support
. Please have the following details of the problem
handy:
Whether the problem happens only at specific times or has only just started
occurring (and what other things have changed at the same time).
If the problem relates to a specific source.
11.1 Your unit does not power up
When powered, you should see power indicator LED illuminated on the front panel
(for A2-7322 and A2-7342 only). If this is not the case, check that the power supply
is plugged in and is the correct voltage and polarity.
11.2 No Audio Output
For the A2-7342 and A2-7322, an incorrect setting of the DIP switches on the rear
panel will blank all audio. Please check that the DIP switches are in the correct
position for the required sampling rate (see section 9).
