We sincerely hope that you never have to read this page, but anyway, here goes:
If all else fails, you can always hit the RESET option in the main window Program... menu.
As a rule, you should first connect power to the board before you start theQV400S software, or at least
before you open a project in the main window.
The green LED on the QV400D is not on or not slowly blinking when the program starts:
Recording does not seem to work:
Playback does not seem to work:
Check that the power supply is connected to the QV400D.
Select the RESET option in the main window Program menu. The green LED should blink briefly,
then the green LED should come back on. From firmware revision M, the red and green LEDs
alternate rapidly. The green LED being on indicates an “idle” condition: it is safe to remove the
ISD chip from its socket. When you exit QV400S, the board is put into a sleeping state (indicated
by a slowly blinking green LED), to allow pass-through of both sound card channels.
Check that the audio cable from your PC sound card line output to the QV400D audio input is
connected.
Check that the red LED comes on when your are sending sound to the chip. (The green LED
should blink while commands are sent to the chip)
Go to the Program/Setup/Parameters Menu and set both volume values (Recording level and
control level) at the maximum (15). If the unit functions with the maximum levels, they can then be
adjusted back down for best quality. If the recording level is too high, the sound quality will be
distorted. If it is too low, the recordings will be “noisy”.
Check to see that the proper chip type is selected. If a wrong chip type has been selected, then
later corrected, it may be necessary to use the Program / RESET option in the main window
menu. The green LED should flash as commands are sent. If it does not, then Program / RESET
should restore proper operation.
Check that you have a speaker connected to the speaker output of your QV400D, or that your PC
sound card speakers are connected to the MM (MultiMedia) speaker output of your QV400D
Go to the Program / Set up / Parameters and set both volume values (Recording level and Control
level) at the maximum (15). If the unit functions with the maximum levels, they can then be
adjusted back down for best quality. .
Check to see that the proper chip type is selected. If a wrong chip type has been selected, then
later corrected, it may be necessary to use the Program / RESET option in the main window
menu. The green LED should flash as commands are sent. If it does not, then Program / RESET
should restore proper operation.
