been damaged in any way, such as power-supply
cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture,
does not operate normally, or has been dropped.
0The mains plug is used as the disconnect device,
the disconnect device shall remain readily opera-
ble.
0Caution should be taken when using earphones or
headphones with the product because excessive
sound pressure (volume) from earphones or head-
phones can cause hearing loss.
0If you are experiencing problems with this prod-
uct, contact TEAC for a service referral. Do not use
the product until it has been repaired.
0Do not remove the external cases or cabinets to

es.
0Do not place any objects filled with liquids, such
as vases, on the apparatus.
0Do not install this apparatus in a confined space
such as a book case or similar unit.
0The apparatus should be located close enough
to the AC outlet so that you can easily grasp the
power cord plug at any time.
0If the product uses batteries (including a battery
pack or installed batteries), they should not be
exposed to sunshine, fire or excessive heat.
0CAUTION for products that use replaceable lith-
ium batteries: there is danger of explosion if a
battery is replaced with an incorrect type of bat-
tery. Replace only with the same or equivalent
type.

Conventions used in this manual
In this manual, we use the following conventions:
0The names of switches, connectors and other
physical parts of this unit are written using a bold
font like this: POWER switch.
0Additional information is provided as necessary as
tips, notes and cautions.
TIP
These are tips about how to use the unit.
NOTE
These provide additional explanations and de-
scribe special cases.
CAUTION
Failure to follow these instructions could result
in injury, damage to equipment or lost recording
data, for example.
Precautions for placement and use
0The operating temperature range of this unit is
5–35 °C.
0Do not install this unit in the following types of
locations. Doing so could cause malfunction.
Places with significant vibrations
Near windows or other places exposed to di-
rect sunlight
Near heaters or other extremely hot places
Extremely cold places
Places with bad ventilation or high humidity
Very dusty locations
0To enable good heat dissipation, do not place any-
thing on top of the unit.
0Do not place the unit on top of a power amplifier
or other device that generates heat.
Beware of condensation
If the unit is moved from a cold to a warm place, or
used after a sudden temperature change, there is a
danger of condensation; vapor in the air could con-
dense on the internal mechanism, making correct
operation impossible.
To prevent this, or if this occurs, let the unit sit for one
or two hours at the new room temperature before
using it.
Cleaning the unit
To clean the unit, wipe it gently with a soft dry cloth.
Do not wipe with chemical cleaning cloths, benzene,
thinner, alcohol or other chemical agents. Doing so
could damage the surface or cause discoloration.

Preparation
Connecting the power
Use the included AC adapter (PS-M1524) to connect a
power supply to the unit as shown below.
Power outlet
DC plug
TASCAM
PS-M1524 (included)
CAUTION
Always use the AC adapter (PS-M1524) that was
shipped with the unit. Using a different AC adapt-
er could cause malfunction, overheating, fire or
other problems.
NOTE
The AC adapter for the unit includes two types of
adapter cords. Attach the type of AC adapter cord
that matches the power outlet that you are using.
Attaching the cord
In order to prevent the cord from becoming discon-
nected during use, attach it to the cord holder (;)
when connecting it to the unit.
1. Remove the cord holder (;) screw.
2. Place the cord in the cord holder (;).
3. Tighten the cord holder (;) screw.
Connecting other equipment
This is an example of MZ-223 connections.
Precautions before making connections
0Carefully read the operation manuals of the de-
vices to be connected and then connect them
correctly.
0Before making connections, turn this unit and all
equipment to be connected off (standby).
0Install all connected devices, including this unit, so
that they are powered from the same line. When
using a power strip or similar device, be sure to
use one that has high current capacity (thick ca-
ble) in order to minimize fluctuations in power
voltage.
0When connecting audio devices, minimize the
channel 1-5 GAIN knobs (j) and faders (8), and
the OUTPUT VOL (q) and PHONES VOLUME (a)
knobs. Failure to do so could cause sudden loud
noises from monitoring equipment, and this could
damage the equipment or harm hearing.
