Condensation can cause the unit to malfunction.

normal playback is possible (about 1 hour). Wipe off any condensation on the
transmitter with a soft cloth before operating the unit.

If trouble occurs
When this product is subjected to strong external interference (mechanical shock, ex-
cessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is oper-
ated incorrectly, it may malfunction.
If such a problem occurs, do the following:
1
. Set the unit to the stand-by mode and turn the power on again.
2
. If the unit is not restored in the previous operation, unplug and plug in the
unit, and then turn the power on.
Note:
If neither operation above restores the unit, clear all the memory by resetting it.
