Notice for 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 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).

FCC Radiation Exposure Statement:

The available scientific evidence does not show that any health problems are
associated with using low power wireless devices. There is no proof, however, that
these low power wireless devices are absolutely safe. Low power Wireless devices
emit low levels of radio frequency energy (RF) in the microwave range while being
used. Whereas high levels of RF can produce health effects (by heating tissue),
exposure to low level RF that does not produce heating effects causes no known
adverse health effects. Many studies of low level RF exposures have not found any
biological effects. Some studies have suggested that some biological effects might
occur, but such findings have not been confirmed by additional research. The WRT­8P has been tested and found to comply with the Federal Communications
Commission (FCC) guidelines on radio frequency energy (RF) exposures.

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 license 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 license is issued on no­interference, no-protection basis with respect to broadcast signals.

Operation of this device 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.

IC Exposure of Humans to RF Fields

The installer of this radio equipment must ensure that the antenna is located or
pointed such that it does not emit RF field in excess of Health Canada limits for the
general population; consult Safety Code 6, obtainable from Health Canada’s website
www.hc-sc.gc.ca/rpb”

Overview

Precautions

The WRT-8P is a plug-on 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 unit is designed for use in
ambient temperature range of
0°C to 50°C (32°F to
122°F).

• Do not place the unit on or near
heat sources, such 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 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.

• Lengthy use of the unit in such
places or not cleaning it after its
use in such places may shorten
its life.

The features of the WRT-8P are:

•Converts a wired microphone to a
wireless microphone via an XLR-type
connector.

•Compact and lightweight metal body
provides high durability and good
balanced handling.

•250 mW high RF output power for
stable long-distance transmission.

•Selectable RF output power: 250
mW/50 mW.

•+48 V power supply capability.

•Switchable input level: MIC/LINE

•Attenuator function allows adjustment
of the audio-input level.

•A backlit LCD provides extensive
information.

•Optimized balance when combined
with the F-112 dynamic microphone.

• When cleaning the unit, never
use organic solvents such as
thinners or benzine, which will
damage the finish of the unit.

• The unit has been factory
adjusted precisely. Do not tamper
with its internal parts or attempt
to repair it.
