Precautions

•Do not place a container with liquid or small metal

objects on top of this unit. Liquid or metal objects inside

this unit are a ﬁre and electrical shock hazard.

•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.

•Be sure to connect to an appropriate outlet with a protec-

tive grounding connection. Improper grounding can

result in electrical shock.

•Do not scratch, bend, twist, pull, or heat the power cord.

A damaged power cord is a ﬁre and electrical shock haz-

ard.

•Do not place heavy objects, including this unit, on top of

the power cord. A damaged power cord is a ﬁre and elec-

trical shock hazard. In particular, be careful not to place

heavy objects on a power cord covered by a carpet.

•Be sure to ground the unit to avoid the risk of electrical

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 heed-

ing 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, mainte-

nance, or repair is necessary, contact your dealer.

•Do not modify the unit. Doing so is a ﬁre and electrical

shock hazard.

•When setting up the product, make sure that the AC out-

let you are using is easily accessible. If some trouble or

malfunction occurs, immediately turn off the power

switch and disconnect the plug from the outlet. Even

when the power switch is turned off, electricity is still

ﬂowing to the product at the minimum level. When you

are not using the product for a long time, make sure to

unplug the power cord from the wall AC outlet.

•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 bat-

tery. 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” connector

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 connec-

tor on the AC outlet is grounded, the unit will be

grounded effectively.

Operating Notes

•The power must be turned on/off using the POWER

switch of this unit. Do not turn the power on/off by

plugging in the power cable, or by using a power strip or

circuit breaker. Doing so may cause malfunctions.

•Do not rapidly turn on and off the POWER switch of this

unit. Doing so may cause excessive current to damage the

system. You must allow at least ﬁve seconds to elapse

between power-on and power-off.

•For this unit, be sure to use a power voltage of the value

speciﬁed in the Speciﬁcations section of this Owner’s

Manual. If you apply a higher or lower voltage, a mal-

function may result.

Rack Mounting Caution

If the unit is rack mounted and transported regularly,

for example, when on a tour, we recommend that the

rear of the unit be supported by ﬁtting a pair metal

brackets, one each side. The following drawing pro-

vides the information necessary to make such brackets.

Note that only one bracket is shown here and the

bracket for the other side must be bent in the opposite

direction.
