Precautions
• Do not allow water to enter this unit or allow the unit
to become wet. Fire or electrical shock may result.
• Connect this unit’s power cord only to an AC outlet of
the type stated in this Owner’s Manual or as marked
on the unit. Failure to do so is a fire and electrical
shock hazard.
• Do not scratch, bend, twist, pull, or heat the power
cord. A damaged power cord is a fire and electrical
shock hazard.
• Do not place heavy objects, including this unit, on top
of the power cord. A damaged power cord is a fire and
electrical shock hazard. In particular, be careful not to
place heavy objects on a power cord covered by a car-
pet.
• Be sure to ground the unit to avoid the risk of electri-
cal shock
• If you notice any abnormality, such as smoke, odor, or
noise, or if a foreign object or liquid gets inside the
unit, turn it off immediately. Remove the power cord
from the AC outlet. Consult your dealer for repair.
Using the unit in this condition is a fire and electrical
shock hazard.
• Should this unit/AC adapter/power supply be
dropped or the cabinet be damaged, turn the power
switch off, remove the power plug from the AC outlet,
and contact your dealer. If you continue using the unit
without heeding this instruction, fire or electrical
shock may result.
• If the power cord is damaged (i.e., cut or a bare wire is
exposed), ask your dealer for a replacement. Using the
unit with a damaged power cord is a fire and electrical
shock hazard.
• Do not remove the unit’s cover. You could receive an
electrical shock. If you think internal inspection,
maintenance, or repair is necessary, contact your
dealer.
• Do not modify the unit. Doing so is a fire and electri-
cal shock hazard.
• When rack-mounting the unit, allow enough free
space around the unit for normal ventilation. This
should be: 10 cm behind, and 20 cm above.
• For normal ventilation during use, remove the rear of
the rack or open a ventilation hole.
• If the airflow is not adequate, the unit will heat up
inside and may cause a fire.
• This unit has ventilation holes at the rear and bottom
to prevent the internal temperature rising too high.
Do not block them. Blocked ventilation holes are a fire
hazard.
• Hold the power cord plug when disconnecting it from
an AC outlet. Never pull the cord. A damaged power
cord is a potential fire and electrical shock hazard.
• Do not touch the power plug with wet hands. Doing
so is a potential electrical shock hazard.
• The digital circuits of this unit may induce a slight
noise into nearby radios and TVs. If noise occurs,
relocate the affected equipment.
• If the message “WARNING LOW BATTERY!” appears
when you turn on this unit, contact your dealer as
soon as possible about replacing the internal data
backup battery. The unit will still operate correctly,
but data other than the presets will be lost.
Before you replace the battery, store your data to an
ATA-compliant PC flash storage card via the CS1D, or
store the data to the personal computer by connecting
the computer to the PC CONTROL “RS-232-C” con-
nector on the DSP1D/DSP1D-EX.
• The unit is equipped with the ground connector to
avoid the risk of electrical shock.
Be sure to ground the unit before you insert the power
plug into an AC outlet.
If the power cord has three pins and the ground con-
nector on the AC outlet is grounded, the unit will be
grounded effectively.
