rental fees) due to unsuccessful recordings caused by
the unit’s malfunction. Before you record important
data, make sure that the material will be recorded
correctly.
The integrated amplifier contains a microcomputer
for signal processing and control functions. In very
rare situations, severe interference, noise from an
external source, or static electricity may cause it to
lockup. In the unlikely event that this should happen,
unplug the power cord, wait at least 5 seconds, and
then plug it again.
Before disconnecting the power cord from the wall
outlet, set the main power switch to OFF.
If during idling the cover is too hot to touch, then
ventilation needs to be improved.
