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, 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.
Avis pour les clients au Canada:
L'usage des appareils sans-fil Sony est réglé par l'Industrie
Canada comme décrit dans leur Cahier des Normes
Radioélectriques CNR-123.
Une licence est normalement requise. Le bureau de
l'Industrie Canada doit être contacté. Lorsque l'opération de
l'appareil est dans les limites de la bande de radiodiffusion,
la licence est émanée sur la base de non-interférence, non-
protection avec les signaux de radiodiffusion.
L'utilisation de cet appareil est soumise aux deux conditions
suivantes : (1) cet appareil ne peut causer d'interférences, et
(2) cet appareil doit accepter toutes les interférences, y
compris les interférences capables de provoquer un
fonctionnement indésirable de l'appareil.

Precautions
· 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 an active 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.
· 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.
· Do not attempt to recharge an alkaline battery.
· Do not dispose of a battery in fire. Do not disassemble or
short-cirtuit a battery.
· Make sure to use an LR6 (size-AA) alkaline battery.
· Make sure the poles of the battery match the + and
markings in the battery holder.
· Remove the battery when the unit will not be used for a
long period of time.

Introduction
The WRT-807A is a UHF-synthesized wireless microphone
for use in a 800-MHz band UHF-synthesized wireless
microphone system.
The WRT-807A operates in conjunction with the WRR-
800A/801A/802A/805A, MB-806A UHF Synthesized Tuner
for vocal concentration.
The WRT-807A can be also used with existing Sony
wireless microphone systems consisting of the WRT-810A/
820A/822A/830A UHF Synthesized Transmitter and WRR-
810A/820A/840A/850A UHF Synthesized Tuner.
The microphone/transmitter and tuners of the wireless
microphone system are classified by frequency band.
A 12 MHz frequency band (or two consecutive-numbered
TV channels, such as 68 and 69 of the U68 model) is
assigned to each microphone/transmitter and tuner model.
In building up a UHF wireless microphone system, be sure
to combine a microphone/transmitter and a tuner having the
same TV channel number.
For the selectable wireless channels and frequencies, see
"Wireless Channel Lists" on page L-1.
Features
Phase Locked Loop (PLL) synthesized system
The WRT-807A features a refined phase locked loop (PLL)
synthesizer circuit.
POWER switch with holding function
The POWER switch can be locked in the ON position to
protect against accidental power cut-offs.
Low-battery notification on tuner
When the microphone battery is low, the microphone sends
a warning to the WRR-800A/801A/802A/805A/850A, MB-
806A in the form of "Battery status information."
This information is sent to the WRR-800A/801A/802A/
805A/850A, MB-806A about one hour before the battery
goes dead to allow the battery to be safely replaced.
When the WRR-800A/801A/802A/805A/850A, MB-806A
receives this information, the LED and the LCD on tuner
panel start to flash.
Powered by readily available battery type
The built-in, high-efficiency DC-DC converter provides
about five hours of continuous and stable operation with just
a single LR6 (size-AA) alkaline battery.

LCD readout of various information
The microphones LCD shows the current channel number,
frequency, input attenuation setting, and residual battery
power.
The accumulated battery use time is also indicated (in one-
minute increments) to allow precise monitoring of battery
use.
Automatic saving of channel and input attenuation
settings
All channel and input attenuation settings are automatically
saved when the microphone is turned off (and are
maintained even when the battery is removed), thus
eliminating the need to make the same settings again the
next time you use the microphone.
Highly reliable electronic attenuator
Adjustable in a range of 0 dB to 21 dB in 3-dB steps, the
built-in input level attenuator reduces signal distortion
during the input of excessively strong audio signals.
Tone signal-incorporated RF carrier signal
The microphone transmits an RF carrier signal that
incorporates a tone signal to enable any tuner with a tone
squelch circuit to pick out only the target audio signal.
Wide dynamic range and low noise
The microphones compander (compressor/expander) system
enables transmission over a wide dynamic range with
minimum noise.
Notes on operation
· When operating two or more microphones, keep the
microphones separated from each other by a distance of at
least 30 cm (1 foot).
· Keep microphones at least 3 meters (10 feet) away from
the receiving antenna.
