WARNING
Batteries shall not be exposed to excessive
heat such as sunshine, fire or the like.
You are cautioned that any changes or
modifications not expressly approved in
this manual could void your authority to
operate this equipment.
For the customers in the U.S.A.
This device complies with part 15 of the
FCC Rules. Operation is subject to the
following two conditions: (1) this device
may not cause harmful interference, and (2)
this device must accept any interference
received, including interference that may
cause undesired operation.
Important Notice
This equipment complies with FCC
radiation exposure limits set forth for an
uncontrolled environment. This equipment
should be installed and operated with
minimum distance 20cm between the
radiator and body (excluding extremities:
hands, wrists and feet).
Notice for customers in the
U.S.A.
Use of Sony wireless devices is regulated
by the Federal Communications
Commision as described in Part 74 subpart
H of the FCC regulations and users
authorized thereby are required to obtain an
appropriate license.
IMPORTANT NOTE: To comply with the
FCC RF exposure compliance
requirements, no change to the antenna or
the device is permitted,
Any change to the antenna or the device
could result in the device exceeding the RF
exposure requirements and void user’s
authority to operate this device.
This device complies with FCC radiation
exposure limits set forth for uncontrolled
equipment and meets the FCC radio
frequency (RF) Exposure Guidelines in
Supplement C to OET65. This device has
very low levels of RF energy that it is
deemed to comply without testing of
specific absorption radio (SAR).
For the customers in Canada
Operation is subject to the following two
conditions: (1) this device may not cause
interference, and (2) this device must accept
any interference, including interference that
may cause undesired operation of the
device.
The term “IC” before the radio certification
number only signifies that Industry Canada
technical specifications were met.
To reduce potential radio interference to
other users, the antenna type and its gain
should be so chosen that the equivalent
isotropically radiated power (EIRP) is not
more than that required for successful
communication.
This device has been designed to operate
with an antenna having a maximum gain of
0 dB.
Antenna having a higher gain is strictly
prohibited per regulations of Industry
Canada.
The required antenna impedance is 50
ohms.
Notice for customers in Canada:
Use of Sony wireless devices is regulated
by the Industry Canada as described in their
Radio Standard Specification RSS-123.
A licence is normally required. The local
district office of Industry Canada should
therefore be contacted. When the operation
of the device is within the broadcast band,
the licence is issued on no-interference,
noprotection basis with respect to broadcast
signals.
AVERTISSEMENT
N’exposez pas les batteries à une chaleur
excessive, au soleil ou près d’un feu par
exemple.

Pour les utilisateurs au Canada
L’utilisation doit répondre aux deux
conditions suivantes : (1)ce matériel ne doit
pas provoquer de brouillage et (2) il doit
accepter tout brouillage, même celui qui est
susceptible d’affecter son fonctionnement.
La mention « IC: » devant le numéro de
certification/ homologation signifie
uniquement que les spécifications
techniques d’Industrie Canada sont
remplies.

Power supply
The transmitter can operate on two LR6
(size AA) alkaline batteries continuously
for about 3.5 hours at 25°C (77°F).
Installing the batteries
1Squeeze the battery-holder tabs inward
(in the direction of the arrows) and
slide out the battery holder.
2Insert new batteries, making sure the
polarities are correct, and then return
the battery holder to its original
position.
Battery indication
The power status is indicated by eight level
indications.
Replace both batteries when the battery
indication starts to flash.
Be sure to check the expiration date printed
date on the new batteries before using them.
The indication is based on the use of new
LR6 (size AA) Sony Alkaline batteries. An
incorrect indication may result when a
different kind of batteries, a different brand
of batteries or old batteries are used. If you
plan to use the transmitter for a long period
of time, it is recommended that you replace
the batteries with brand new ones.

30 Important notes on operation
Important notes
on operation
Notes on using the
transmitter
• The digital wireless microphone system
product must be used within a
temperature range of 0°C to 50°C (32°F
to 122°F).
• Operating the transmitter near electrical
equipment (motors, transformers, or
dimmers) may cause it to be affected by
electromagnetic induction. Keep the
transmitter as far from such equipment as
possible.
• The presence of the lighting equipment
may produce electrical interference over
the entire frequency range. Position the
transmitter so that interference is
minimized.
• To avoid degradation of the signal-to-
noise ratio, do not use the transmitter in
noisy places or in locations subject to
vibration, such as the following:
- near electrical equipment, such as
motors, transformers or dimmers
- near air conditioning equipment or
places subject to direct air flow from
an air conditioner
- near public address loudspeakers
- where adjacent equipment might
knock against the tuner
Keep the transmitter as far from such
equipment as possible or use buffering
material.
On cleaning
• If the transmitter is used in a very humid
or dusty place or in a place subject to an
active gas, clean its surface as well as the
connectors with a dry, soft cloth soon
after use. Lengthy use of the transmitter
in such places or not cleaning it after its
use in such places may shorten its life.
• Clean the surface and the connectors of
the transmitter with a dry, soft cloth.
Never use thinner, benzene, alcohol or
any other chemicals, since these may mar
the finish.
To prevent electromagnetic
interference from portable
communication devices
The use of portable telephones and
other communication devices near
the DWT-B01 may result in
malfunction and interference with
audio signals. It is recommended that
portable communication devices near
the DWT-B01 be turned off.
