* Do not touch the cooling vents on the sides of the DB-900; they
can become very hot during operation.
* This unit is equipped with a protection circuit. A brief interval
(a few seconds) after power up is required before the unit will
operate normally.
* Always make sure to have the volume level turned down before
switching on/off power. Even with the volume all the way down,
you may still hear some sound when the power is switched on/
off, but this is normal, and does not indicate a malfunction.
