LEDs flash slowly, system does not respond:
There is noise on the control (usually right) channel during command operations:
The recorded sounds are weak, or loud and distorted:
Some phrases are stuck together during playback:

From revision M, in any mode, should the red and green LEDs begin blinking slowly in any pattern
except green only (which signifies lockout mode), a transmission error has occurred. The control
level should be adjusted to improve the communications, but if this fails, call or email Quadravox
and report the pattern of the LEDs.
Go to the Program/Set up/ Parameters menu and decrease the control volume setting. If the
setting is reduced too much, the unit will stop responding to commands.
Check to see that your sound card mixer controls are set for maximum gain, and that the wave file
input is enabled. Individual wave file gain settings are made automatically by the QV400S
program. It is best to disable all other inputs to minimize potential noise in the control signal.
If this does not improve the problem, check the switch channels box

This may be due to the “epsilon” factors that try to compensate for the uncertainty on the
ChipCorders’ sampling frequency. See epsilon.
