WARNING
Batteries shall not be exposed to excessive heat such
as sunshine, fire or the like.
If the transmitter develops an abnormally high
temperature, a burning odor or smoke during
use, remove the battery holder and stop using the
transmitter immediately.
Take care not to burn your fingers when removing
the battery holder as the batteries may be very hot
at this time.
For the customers in the U.S.A.
Use of Sony wireless devices is regulated by the
Federal Communications Commission as described
in Part 74 subpart H of the FCC regulations and
users authorized thereby are required to obtain an
appropriate license.
You are cautioned that any changes or modifications
not expressly approved in this manual could void
your authority to operate this equipment.
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 the 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 ratio
(SAR).
For the 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, no-protection basis with respect to
broadcast signals.
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.

The unit is designed for use in ambient temperature
ˎ
range of 0 °C to 50 °C (32 °F to 122 °F).
Do not place the unit on or near heat sources, such
ˎ
as lighting equipment, power amplifiers, or in a place
subject to direct sunlight or excessive moisture. In
such places, the external finish or internal parts of
the unit may be damaged.
If the unit is used in a very humid or dusty place or
ˎ
in a place subject to expose to an active or corrosive
gas, clean its surface as well as the connectors with a
dry, soft cloth soon after use.
Precautions
Lengthy use of the unit in such places or not cleaning
it after its use in such places may shorten its life.
When cleaning the unit, never use organic solvents
ˎ
such as thinners or benzine, which will damage the
finish of the unit.
The unit has been factory adjusted precisely. Do not
ˎ
tamper with its internal parts or attempt to repair it.
When defective conditions are encountered, batteries
ˎ
inside the unit may produce heat. If this happens, do
not touch the batteries directly with your hands.
Overview
The WRT-822B is a transmitter for a UHF synthesized
wireless microphone system to be used for broadcast
or movie production purpose. This transmitter is
suitable for Electronic News gathering (ENG) and
Electronic Field Production (EFP).
The microphone/transmitter and tuner of the wireless
microphone system are classified by frequency band.
A 24-MHz frequency band is assigned to each
microphone/transmitter and tuner model. In building
a UHF wireless microphone system, be sure to
combine a microphone/transmitter and a tuner having
the same wireless channel (frequency).
Features
The features of the WRT-822B are:
Phase Locked Loop (PLL) synthesized system
Compact and lightweight
Remote battery alarm on tuner
Operation powered by easily available batteries
LCD for coordinated operation control
Saved channel and input attenuation settings
Highly reliable electronic attenuator
Compatibility with Sony lavalier microphone
RF carrier with tone signal
Wide dynamic range and low noise
Notes on Microphone System Operation
To operate with two or more channels, maintain a
ˎ
distance of at least 30 cm (one ft.) between each pair
of transmitters.
For details of operation with two or more channels,
refer to the Operating Instructions for the WRR-855S/
862, etc.
Ensure that the tuners set to channels not being used
ˎ
are either turned off or set to the minimum output
level.
When powering the transmitter on or off, to keep
ˎ
the noise to a minimum, set the audio output level
from the tuner or mixer to a minimum.
Powering the transmitter on without checking
ˎ
the channel selection first may interfere with the
operation of other microphones/transmitters, if the
current setting is already being used.
To prevent noise generation, keep the microphones
ˎ
and transmitters at least 3 m (10 feet) away from the
antennas when the system is operated using a group
which allows selection of up to 11 channels, and at
least 6 m (20 feet) away when using a group which
allows selection of 12 channels.
When there is a strong interference signal around
ˎ
the microphone system, such as an interference
caused by an active handyphone, noise may occur on
the microphone system.
